  • The left side gear planetary has a 2 pieces lobe wheel wich is moved when the barrel counter weights locks .Then press the friction clutches .That is ok.

    What i don understand is how are pressed or released the clutches wich are behind the right planetary gear,cause this does not have a lobe wheel...

  • Y do u need this stupid ball of plastic and metal...just recycle it...it does nothing to me cuz i dont get it...i lost u at the first word u said...boring video

  • @brandon54321att It is true that this video is not as exciting as your xbox, but I can't take credit for making it, just posting it. And don't worry about not being able to understand it now, maybe when you get a little older you'll be able to figure it out....?

  • So in theory, if I put a heavier spring, OR turn added some turns onto the existing spring on the counter weight you could have you the differential remain locked longer?

  • @Metallica1071991 I think if you made the counter spring stronger it would probably raise the speed at which the locking feature becomes disabled...? So I think this wouldn't necessarily make it stay "locked" longer, just have the ability to "lock" at higher vehicle speeds...?

  • @tubeoverton Bingo. But I'm not about to try it on my truck.

  • At what speed/rpm does it engage/disengage?

  • @CowboyPenner The locking action of the differential doesn't kick in at an exact speed. It begins to lock whenever there is a difference in speed between the left and right axles of about 150 rpms. However, the locking feature is mechanically disabled at speeds above 25 mph for safety purposes. (cornering at speeds above 25 mph with locked rear end could cause severe "fish tailing" and loss of vehicle control).

  • @tubeoverton Thanks for the info. Here's another question that I've been tryin' to figure out. How do I engage the differential so that it has a chance to work properly? Do I need to roll on the throttle slowly and keep the engine rpm's at a certain level or the back wheels spinning at a certain speed?

  • no problems with mine 190K miles with original transmission and motor and no problems!!

  • Thanks for the feedback! I also have one in my 04' Trailblazer. It's the best vehicle I've ever owned, got 125,000 on it and have used the lock up feature many times and like you, I haven't had any trouble. I serviced the fluid in it @ 75,000 and probably will again @ 150,000. I plan on doing a video of that service when I do it and will share with you guys. Granted, I don't do the "off-road, try to tear something up stuff ", but it worked really well in the 6" of snow we had recently.

  • @tubeoverton My truck see's its fair share of mud and slick stuff, so i know eaton did something right. The locker is best used for me when crossing a ditch, because it throws one wheel up in the air and tucks the other one in the fender well, but with the g80 it keeps on going. My dad has a 2000 2wd silverado 1500 with 165K miles on it and im pretty sure it has a g80 and it has absolutely no problems once so ever.

  • youll love what i got to show you, busted case, shatterd really, maximum carnage. wiped out everything. 

  • Sounds like, to me, that the G80 works just like the Eaton No-Spin diff / Detroit Locker...However, the G80 is a lot more complex in design / function. Because of the more complex design / function, i'm not too sure that I like it! Think i'll stick to a Eaton No Spin / Detroit Locker!

  • I know it's more complex that a conventional limited slip differential for sure. Surprisingly enough though, we haven't seen much trouble out of these units. I believe that in all the years of it's inception that I have only seen 2 come into our shop with an issue. I agree that simplicity is golden and that if you have had good luck with something, stay with it.

    Thanks for the feedback.

  • if you locked this hunk of crap up at those speed i gaurrentee that it would blow right the fucck up. these things are only precceded in thier shityness by the modern chevy tcases, 246,261,and 263.

    the sad thing is that i am a devout chevy man and you couldnt give me a modern chevy.

  • @tubeoverton you must work at a slow ass shop or a shop more based around overall mech. work. i work at a diff/4x4 shop. we are slow as hell and still have to replace these thing at least once a month.

  • Chevy dealer

  • @tubeoverton well no wonder you dont see to many, the cust. already got fucked in the ass when he bought the truck he sure as shit isnt going to take it back to gm for round 2 of the ass pounding.

    call any axle shop anywhere in the country and tell them that you WANT to install a g80 or ask them what they think of them.

  • It's probably due more to the higher labor rates that we charge, that's true. I think it's round $90 and hour. Anyway, you have raised my curiosity about em. We have a 4x4 shop on the other side of town that we have a purdy good relationship with. I'll drop in on those guys sometime and see what they know bout em. I thought about you when I went to sleep last night for some reason when I said my prayers. I wasn't sure why, don't know what you got going on in your life, but I prayed for you.

  • @tubeoverton

    i got twins coming so ill take every bit of help i can get.

  • So at high speeds the locking mechanism does not engage because the centrifugal force pulls the pawl away from the fly weights, did I understand that correctly? So say you're going 40mph and on an icy upgrade then the differential would act as an open differential, correct?

  • I don't think that if you were going up an icy upgrade @ 40 mph that you would have to worry bout slipping. However, if you did begin to slip your upward speed would theoretically decrease until the speed at which the locking feature was re-enabled. At that point, you would have normal locking capability.

  • @tubeoverton In northern minnesota (Duluth) where we experience a lot of hills, I do often find myself in situations where I could be going 50+mph and hit an incline where I need to maintain my momentum, but since it is ice the traction is near nil so even at those speeds you tend to spin your tires a good amount. In theses cases it would be ideal for the driver to have maximum traction in order to maintain the current momentum. I don't see it as ideal that I need to reduce my momentum.

  • i think i perfer the clutch type diff dont kno why but yeah

  • You'll have to admit that a child could choke on the small parts.

    An adult would choke on the larger parts.

  • Comment removed

  • unsafe to hard work

    jeep QuadraDrive go better

  • i'm guessing thats wat in my 2009 gmc serria z71

  • if it has a g80 code in the glove box yes

  • yes it is.

  • @meandatoilet  Yes.

  • @meandatoilet its in all the gm trucks and suvs
