Jeep Commander Quadra Drive II / The best stock automatic system

[hoagieman26]

At founas007 that commander doesn't have quadra-trac one at all. It has quadra-DRIVE two which has rear front and center locking diffs.

[deanbassist01]

What do you base your "best stock automatic system" on, having not tested any competitors. Jeep is far from the best at anything, except gathering the worlds stupidest car consumers.

[Ju7lenda]

surprised

Whts the song in the background?

[krawler00]

man, that needs a solid axle in the front. It would be saweet!

[tanhelmet]

Thanxz buddie. I don't know what I have since I bought the jeep from the inlaws. It's a 2008 with the 3.7 . Unlike my wife's liberty there's no transfer case shift . Is it all wheel drive? Is that good ? All it has is the shifter with a plus or minus sign. It's got the badging and I can see a front differential . Help me out. Can I still go off road ? At what speeds. ? Is there something I have to do like shift to neutral ??

[Founas007]

@tanhelmet: if you can see a front differential, but you don't have a shifter, then you have all wheel drive with Quadra Trac I. It works pretty well, but nothing for serious offroading. there are no lockers, just traction control.

[tanhelmet]

Quadra drive 2 is that on 3.7, 4.7 or 5.7 ?

[Founas007]

@tanhelmet: 3.7 never had Quadra Drive

[ChiefSpooshme]

A stock 2001 Cherokee would WALK up this without any off camber issues!

[eminded]

this is waht i do everytime i pull into my driveway

[AC23Xx]

andddddddd.... PARK!

[Righty736]

There is a scary lack of flex there

[kingdomboost]

@Righty736 C'mon, it's not a rig. This is excellent for factory.

[SPCHILLIN718]

Ummm... that was awesome! Nothing's better than a Jeep!!!

[TruthNTuning]

@CoyoteStieTinkBig

Then shut your god damn mouth, anybody looks at any comment you make on any other car video and it's painfully obvious that you have no idea what you're talking about.

[millicentbistander]

That music is PIMP.

[kens97sto171]

@CoyoteStieTinkBig

New Toyota's are not durable for off road, Land Rover and reliable are not two words that go together, plus here in the states they are serious money to own. Now an old Toyota Land Cruiser, nice stuff, but again not many left around here.

If you want a comfortable vehicle that can do some serious offroad your only real choice is a Jeep. Rubicon trail is some serious stuff, your right about the driver being important, But the Rub trail u need a good machine too.

[kens97sto171]

@CoyoteStieTinkBig

Actually Jeep is one of the best selling brands Chrysler has. As to who uses Solid axles.. UMM Land Rover. and every heavy duty truck in the world. Solid axles are strong and simple that's why they use them. Also if you engineer it correctly they can ride pretty good too. Not sure who you are comparing too, But try and take that brand on the Rubicon Trail... see who breaks down first.

[duxante]

That's a good driver.

[Psi4tsi]

It doesn't take "time" to lock the diffs...it takes wheel speed/spin....

[ilus101]

i thought they still made these up until 2011??

[ilaydaksk]

@ilus101 You are right.

[sincityskywalker]

i have an 06 commander and its the biggest piece of shit

i've ever owned

[SNIPE1T]

@sincityskywalker

you are fucking stupid, i have owned over 30 car the last 15 years.

And the Commander is the best car of them all. I live in the mountains, and the commander is BEST

[MySamisbest]

do they still make the commander? and I think I will get a commander someday I know for sure I will

[Founas007]

@MySamisbest: Nope they don't

[GmTruckCarLove]

@MySamisbest Look at CarMax. That is were I got mine; they are great rigs! Feel just like a new Jeep and it has 87K on it!

[kaga1310]

just stupid

[Destroyeron]

I can't believe how little flex that has.

[ShottsUZJ100]

Hilarious! You guys need to drive a vehicle with real locking diffs. Until then go ahead and think what you wish. I'd a LOVED to see this guy shoot the same video on loose dit and gravel. That thing would be clawing and slipping a jerking like all hell becuase they're only LSD's. LOL!

[casperman32]

what were the noises it was making from 2:29 to 2:40??.....great vid, set of 33" on that would work real nice

[Founas007]

@casperman32 This sound normally comes from the differential when your turning and differential is trying to stay locked.

[partymaster5boy]

@casperman32 lol bro that was the back tire being forced into the fender, and possible this guy tapping the camera

[cdawg4391]

@casperman32 It's my experience that the sounds come from a weak/worn front drive shaft joint coming out of the t-case - at least thats the case with my 03 liberty.

[TJvigilante]

You know what I noticed when these "lockers" kicked in? YOU STEPPED ON THE BRAKES. You know what that does? That provides resistance to the wheels in the air which in turn divides power to the wheels on the ground. It's not a locker, it's a poor man's traction aid. You can do it in anything with any kind of limited slip system, even with a solid-drive transfer case (command-trac).

Damn, you commander drivers are some stupid mofos.

[Founas007]

@TJvigilante: nope, as you can see the engine is in idle. Brake lights on doesn't mean "braking"

[TJvigilante]

@Founas007 If you knew much about how a vehicle worked, then you'd know that yes, when the third brake light is lit, you are indeed braking. I can clearly see the third brake light illuminated. Now, whether it was from you having your foot on the brake, or from the traction control system applying the brakes for you, who knows? But I know from the video that it's not diff locks that are giving you traction, it's active braking. Notice how the wheel in the air doesn't turn while you move.

[Founas007]

@TJvigilante: No, when the brake light is lit, the brake switch is engaged. In my video my left foot was on the brake pedal. Because of this the light came on but the brakes were not engaged. If I was braking I would have needed higher rpm to keep the vehicle moving. But as you can see, the engine is still at idle. So there was no braking at all. The main thing is: Quadra Drive II = Eaton EGerodiscs differentials = lockers, this is a fact.

[TJvigilante]

@Founas007 That only happens when you have brakes applied to that wheel. If you had a differential locker, it would turn at the same speed as the other wheel on that axle. If it were open without brakes applied, it would be spinning. If it were on a limited slip differential, it would be turning at the same speed as the other wheel until the clutches broke loose, then it would act like an open diff, spinning the free wheel.

[Founas007]

@TJvigilante: As I mentioned before, the 2005-2010 Grand Cherokees / Commanders (with Quadra Drive) have front and rear "lockers" from Eaton (EGerodiscs). So no open diffs, no traction control. You are posting incorrect information which will confuse others.

[tak2w]

@TJvigilante This system is definitely NOT actuated by the brakes like you can do in an open dif vehicle. I own a Commander with QDII and I have owned several open dif Jeeps in the past. Huge difference!

[xXSniperzzXxGA]

i think my 2001 volvo s40 has more travel than that thing

[Luisgtm95]

My life from now on will be just terrible because I can´t do that in my 4-Cil VolksWagen

[greenjeens]

We have an 06 jeep commander 4 wheel drive. I didn't know it could do this. I thought they were open diffs.

[Founas007]

@greenjeens: It depence on the system, this is Quadra Drive II. Other systems use traction control.

[ShottsUZJ100]

You guys call it what you like. Eaton NEVER uses the work lock or locker for the Jeep's diffs. If you're a Jeep lover then learn from the Wrangler Rubicon. Those are locking diffs that send 100% torque equally to both wheels on the given axle. The diffs in the Commander/GC are limited slips and nothing more. You "talk" as though you wish you had the Rubi's diffs....but you do not. Sorry.

[tyek025]

@ShottsUZJ100 Posted from Eaton's website: EGerodisc Differentials

EGerodisc™ is a hydraulically-operated electronically controlled limited slip differential that provides variable torque up to full axle lock. It automatically identifies the optimal traction solution at any speed. The EGerodisc™ is a commercially proven technology in production on the Jeep Grand Cherokee. This proves they know what they're talking about. They said they're not 100% lockers and this even says up to full axle lock

[jcaled24]

The wheels lock and turn together..... call it whatever the fuck you want to.

[ShottsUZJ100]

Not trying to be mean...but why do you-all (including jdstephens) call these lockers when they are not? The non-2011 and in fact NO Grand Cherokees have EVER had front lockers. I know you wish they had them by the way you post and talk in that video. Sorry though...they do not have them and there's a huge difference between ELSD's in the GC and real lockers.

[Founas007]

@ShottsUZJ100: As I already replied earlier, I know they are not 100% lockers, but they act similar as they are able to transfer almost 100% of torque on both wheels. The 2005-2010 Grand Cherokee /Commander have front and rear "lockers" from Eaton (EGerodiscs). The 2011 are only equipped with a rear Eaton locker.

[Founas007]

@Jdstephens007: Jap, I'm planing to test the 2011 GC. The only problem is, I don't want to buy it, because I don't like the car. I hope, I will be able to borrow it soon.

[95chevyboy]

to answer ur question, the jeep knows when to "unlock" when it sees all the wheels turning at the same speed

[ShottsUZJ100]

Why do you keep calling them "lockers"! The only locking diff is the center. The front and rear diffs are Limited Slips. They are NOT lockers. I like your ramp video though the data/information is flawed. Quadra Drive II is a traction controlled systeem using ELCD diffs. Nothing else and not close to being a triple locked system.

[ShottsUZJ100]

@ShottsUZJ100 Sorry...."ELSD" not ELCD.

[Founas007]

@ShottsUZJ100: Well they are not 100% lockers, but acts similar. I didn't find a point when they are start slipping, so from my point of view they acts as lockers.

[offfiman]

@ShottsUZJ100 They are electronically controlled differentials that use a clutch pack, It can up to "lock" 100% automatically. Only the name is ELSD but it doesn't mean anything, no ELCD, LCD is a screen type, lol. It first senses the slip by the sensors in the vehicle, after that it operates the clutch pack, and it can move momentum where it's needed. It's just almost as efficient as 100% manually operated locker like ARB, it does 98% of what the ARB does. So in a very few places you need more.

[TJvigilante]

@offfiman Wrongo chief. The only sensors are wheel speed sensors which apply brakes to the wheels in the air. This transfers the torque to the other wheel. No special magical differential needed...you can do it with open differentials and cutting brakes. Try it sometime...get an old open-diff cherokee, put line locks on the two front brake lines. When you get one tire in the air, hit the brakes, hit the line lock for the one in the air, then let off the brakes. It'll do the same thing.

[Founas007]

@TJvigilante Traction control (you are talking about) and ELCD diffs are completely different systems. Check it before you post..

[offfiman]

@TJvigilante You are talking about traction control. And yes traction control can do quite much too, but it's called Quarda Trac 2. Quarda Drive 2 is totally different, it is based on these, special type of differentials and is capable for 100% locking. It is a better system than traction control, although, traction control is very good too. And real manual lockers are the best. ;)

[justinsparc]

@offfiman Agreed this isnt a demonstration of lockers or QDII, his commander might have QDII but the diffs arent locked. It has to be in 4lo for the diffs to lock. This is traction control.

[jumpr31122]

@justinsparc

Was he not in 4lo ? I'm 100% certain his lockers are engaging. That clicking sound isn't a u-joint someone mentioned earlier. It IS the lockers. It's not made to lock up 100% solid. The clicks are the diffs slipping to prevent binding and breaking shit. An auto-locking Detroit will do the same thing on the highway although there are different components inside that are causing the sounds.

[ianmma]

Founas... Do you have any experience with the LR4? Curious how the 2010 Commander and LR4 fair against each other in a shootout. Kind of surprised there isn't any comparisons out.

[Founas007]

@ianmma: I have no personal experience with the LR4, but as far as I know, it has no front locking differential and I have no idea how locking central and rear (option) differential works on the LR4. My guess is that the WK with Quadra Drive (manual central locker and automatic rear and front lockers) would perform better offroad then LR4.

[ajparshall]

@ianmma i have been out wheeling with some lr4's and i was ina comander overland qd2.. btw the commander does not have lockers like this guy says... there is no locking mechanism in rear or front axle it is all electronically controlled to each wheel the qd2 however is still the best system on the market hands down.. for stock

[offfiman]

@ianmma Jeeps Quadra drive 2 is excellent, one of the best 4x4 systems. But in the other hand, LR4 has far better suspension, being airsuspension. Offers more wheel travel, and more clearance. LR4 does not have a front locker, but it has a very good traction control, that does probably 90% of what the Jeep's Quadra Drive does, so it replaces the front locker at most cases. Only at most extreme stuff, the Jeeps 4wd is visibly better. Both are good at their own way.

[dkia09]

do u think some 1 can do this with the quadra trac system and another question doesent traction control act the same a lockers?

thanks



[Founas007]

@dkia09: no, quadra trac with traction control needs the wheels to be continously spining in order for it to act. when you stop the car with one wheel with poor traction the traction control doesn't know what to do for first few seconds before traction control begin to engage again. quadra trac with traction control is not a bad system, but you will reach the limit of this system quite fast and is hard on your brakes (as traction control uses the brakes to asist it).

[dkia09]

@Founas007 thanks for the reply so a quadra trac 1 cant do this because the wheels need to keep spinning until the traction control starts to use the brakes?

[Founas007]

@dkia09: What year and type is the vehicle you drive? QT 1 is the most simple version of 4x4 systems by Jeep. It doesn't have low-range. You can drive it on unpaved roads, on snow, etc without any problems, but serious offroading is not possible with this system.

[dkia09]

@Founas007 i have an 06 commander

[jojsurf]

Drive a stick shift its actually a challenge! HEY CHECK OUT THIS 88 XJ JEEP WITH NO LOCKERS 2 INCH LIFT AND 30 INCH TIRES ----CLEGHORN HD 2011---- ON YOU TUBE

[rayamanelly]

So that's what happen to our warehouse door.

[Greg9942]

I had a 2001 V8 with QuadraDrive. Its a great system. I thought the mileage was awful. I have heard that the newer ones get better mileage. My neighbor's son has one with the V6 that his wife drives. He has a Ram with the Hemi. He says the Hemi in the Jeep gets better mileage because it doesn't work as hard to move the vehicle..

[RaguelAngelofBalance]

@Greg9942 Exactly. A V6 has no business being in a 5700 lb vehicle.

[RoverT988]

I lol'd at 1:35

[JackKangaroo1]

Is this a demonstration on what happens when a drunk tries to drive up a ramp?

[smellytoilet1996]

It hearts my ear whenever the asphalt scratches the chassis of that beautiful Jeep.

[funkeyman606]

this is legit, crazy

[EmoKevin93]

Heartache when i was watching this video . My family have this car and we try our best to maintain the car thats why ...

[Kingrichard345]

@ Faunos007

Not positive about my last statement.

I know it works with quadradrive 1 because of the gerotor pump and clutches (vari-loc) to transfer torque in the transfer case and front and rear (in hi). Low locks front and rear together so, vari-loc side to side.

My question is, does quadradrive 11 transfer torque in high and where and how.

I really really love quadradrive 1 in my 04 overland.

[fitbmxseries1]

hopfully picking one up this weekend for my fiancee, should i go with the 4.7 or the 3.7? whats more dependable?

[Founas007]

@fitbmxseries1: you must ask yourself, if you want more power or not. The 4.7 has much better torque then the V6 3.7. for 2008 and up the V8 4.7 was modified so the HP and torque was increased. I would prefer 2008 V8 and newer, or the HEMI 5.7L from 2009.

[2000ViperGTS]

@Founas007 Any HEMI is great for power and I had an 08 4.7 WK and currently have an 06 HEMI WK. Check my 70+ videos if you want to wheel in a WK :-)

[1ownjoo2]

@fitbmxseries1

I would have to say get the V8, the commander weighs ALOT, and that tiny V6 engine is going to be using alot of gasoline to keep the pace up.. That extra power and torque on the V8 will help you keep the RPM's down and probably use less or the same gas.

[RaguelAngelofBalance]

@fitbmxseries1 If you get the 3.7 V6 I will laugh.

[fitbmxseries1]

@RaguelAngelofBalance be prepaired to laugh.... i got the grand cherokee with v6.... its slow and burns more gas then the v8 after i put the lift and new tires on it. i thought the awesome price was worth sacraficing the v8...it wasnt.

[RaguelAngelofBalance]

@fitbmxseries1 I believe it. The ONLY reason these V6s are offered is for a lower base price. I am always willing to sacrifice MPG for power, but with the 6 and the 8 it is no contest. ALWAYS go with the V8 in a mid size sport ute.

[jojsurf]

@fitbmxseries1 WHAT YEAR? THE OLD CHEROKEE LIKE 88- 95 NOT THE GRAND ARE VERY LIGHT AND GREAT FOR OFFROAD AND ROCK CRAWLING.

[Kingrichard345]

Yes- raise the front end (tires not touching ground) spin one wheel if the other wheel spins in opposite direction freely then u have open front diff and would not be quadradrive

[bomfunkportugues]

hi, how i can identify if a commander have quadra drive o quadra trac sistem?

[Founas007]

@bomfunkportugues: the easiest way is by the label near the gear shifter. the label will say Quadra Trac, or Quadra Drive. Vehicles equiped with Quadra Drive has also a label on the rear door

[jeep5253]

@Founas007 The Commander does not have a badge that says Quadra-Drive anywhere on the outside of the vehicle. Also, the Commander does not have a badge near the shifter that says Quadra-Trac if it has Quadra-Trac. It does have the Quadra-Drive badge near the shifter.

[Kingrichard345]

The creaking has to be all the wheels locked together and binding during the turn. Has to be the lockers however it locks.

[jeep5253]

@Kingrichard345 The creaking (racheting) sound is the Traction Control engaging. This can be turned off for off-roading.

[Kingrichard345]

You should have more than 3" of flex before you can call a vehicle "Trailrated".

[tripovermyego]

What is that popping noises while your in the sand?

[Founas007]

@tripovermyego: came from locking and opening the differential

[garp]

@tripovermyego

creaking suspension maybe?

[jeep5253]

@tripovermyego That is the Traction Control.

[benzguylv]

Great video that's what I call trail rated

[tcmlr]

what about quadra trac 2... doesnt the front and rear lock? or does it

[Founas007]

@tcmlr nope, it doesn't.

[proonehander]

almost crashed the building..

[jeep4jeep]

What tyre pressure are you running for the sand?

[Founas007]

@jeep4jeep: usually 7-10 psi

[mdrpdj6]

does my limited 5.9 lock like that???

[Founas007]

@mdrpdj6 It's 98 ZJ, right? Then no, QD II is in the Grand Cherokee and Commander from 2005.

[RuBerSideDwn]

@mdrpdj6 limited 5.9 what? jeep commander came with a 5.7 hemi a 4.7L flex and non flex fuel and a 3.7L V6 thats the engine options. comes with three 4wd systems featured here the QD2. also comes with the QT1 and QT2

[Dwealdric]

@RuBerSideDwn He's talking about the 98 GC. It had a 5.9L V8 option.

[xamicolo]

never!

[Founas007]

I don't remember, sorry :)

[braineyboy]

whats the name of you backround music

[rangerover06sc]

Looks like the traction control system works well in these conditions,theirs hardly even a hint off wheel spin,kudos to jeep,its a shame their discontining the commander

[AudiROCKS]

sick driving skills man!! I wonder if my moms commander v6 can take this

[Founas007]

:) thx

[mustannicolas]

@AudiROCKS lol

[xvrhernandez349]

thats so cool, but if i was a passenger or the driver i would be freaking out

[Theriomalstrom]

Remind me not to let you drive my car....

[tCson]

I really thought that thing was gonna flip.....

[MiStaVP05]

this is accidentally the funniest video I've ever seen. I love Commanders. and QDII!

[skaterboy52093c]

commanders are so top heavy and big. new jeeps have no ground clearance(excluding wrangler) even the new 2011 jeep with the stage2 lift, witch gives you 11 inches of clearance. WTF my 1996 zj stock suspension has 14 inches of clearance.

[skaterboy52093c]

new jeeps have no flex whats so ever

[SendersBarag]

Formidabile!!!

I love the jeep

[lolnumpty]

the problem is the car is so nice inside.... you dont want to do that with it xD i just bought the 3.0 of this today, not as slow as people are making out, but i think they forget what a big ass 4x4 is really used for -.-'

[luuvjeep]

Put a cold air intake in it gives you a little extra that is nice.

[lolnumpty]

@luuvjeep i got an engine remap, it really moves now, im happy, maybe i will look at an intake

[Amras0407]

Jeep needs to move back to solid axles...

[JeepMan19007]

@Amras0407 The wranglers have solid axles....

[Amras0407]

@JeepMan19007 I'm aware of this...but they're the only remaining Jeep model sold in America that has solid front and rear axles. The XJ and the WJ were the last non-wrangler with solid front axles.

[sampwell819]

this is the quadra drive II, with dana hydra-lok limited slip diff to full locker with the pressure of oil, fastest transfer, and can transfer with wheel in the air (some other cant transfer with 2 wheel in the air.

in 2006 jeep is equiped with traction control.

[WJguy420]

did you have it in 4LO?

[Founas007]

sure

[WJguy420]

i thought so, i dont think QDII could do that with the torque transfer system (except in 4LO)

[mvambrose]

sweet vid man! i aslo have a commander 07 rocky mountain edition love it! i belive its the quadra drive ll correct? it has no 4whl lo. just fulltime all wheel drive. please respond w/info on the system.

[Founas007]

Thanks. Your Commander doesn't have a QD II. It has TCS (traction control) which works pretty well, but way different then QD II.

[TOONCAS]

5-star rate from Toronto! Great vid!

[dforty40]

I'm happy to see you did the Quadradraive two test as promised

[mememojo]

Why was it making noises that sounded like gears crashing.

[Founas007]

Good question. I believe its the locker (another option is TCS, but its too loud and a„hard of a noise for brakes). In sharpe turns when the differential was locked before it always makes these kind of „clicking noises. When you watch the wheels on one axle, you can see the locker release a bit and lock again. How it works exactly I have no clue. If I have some free time, I will open the diff and check to see how it exactly works.

[wodanowitz]

Hello Founas007...... nice video and yes I agree that the QD2 is much better then the QD .... but.... I still think the gerotor pumps in the axles of the GC you had with QD in that other video, were not working as they should.

Five Stars for this video, thanks for posting.

[Founas007]

Thank you. I still believe the QDI was ok, but you may be right. I want to make it clear, so I will get a hold of a Jeep WJ, test it and post the results.

Check video named: 'Jeep Grand Cherokee climbing onto road' The QD I of this Jeep acts exactly the same way as mine did - slow, with higher rpm and without spinning the second wheel. But as I said I will test it again with different WJ and post a result here.

[geochafg]

AWESOME! I am almost sure that you also have 2 trac-lock diffs ;)

[bobodobo1]

Thanks, this and your other videos are very informative. It would be interesting to do side by side comparisons of the Jeep Quadra-drive system to vehicles built by other manufacturers.

[Founas007]

Thanks. I would like to do it, but majority of other vehicles have open diffs, limited slip differentials, or TCS (electronic traction control), but nothing similar to QD. Fortunately you can buy stock vehicles with locker that are manually engaged such as Wrangler Rubicon, RAM Power Wagon, Mercedes G, etc, but these cars are way different. This fact makes the Jeep Quadra Drive system the only and the best factory option on the market for offroad use you can buy in this class of cars.

[JEEPOFFROADV8]

i have a 04 0verland with quadradrive1. my question is is quadradrive2 that much better? i have been told by jeep engineers that the old system was better less to brake and just as good for traction. in the snow all 4 will spin. so what do you think??

[Founas007]

From what I have tested, the QD II acts more like lockers were the QD I acts as inteligent limited slip differentials. I dont want to say QD I is a bad system, it just depends on your expections from the system. When you drive your car as a daily driver most onroad and light offroad conditions such a snow, light mud and other light offroad slippery conditions then QD I will work perfect for you.

[luuvjeep]

I think the main difference is no 4low but how often do you use 4low? I had 2 jeeps before my commander and never needed to engage the 4low.

[benspilk900]

Wow that is impressive
