Spider gear tilt causing "clunk"? (PLZ read desc.)

[grngs1]

Your slip clutch perload springs are worn

[DarkPrince013]

Also, u-joints good.

Did you ever figure it out? I have an 83 F150 and it "clunks" when I change gears. From first to second and to third. I have the 8.8 also with the SROD 4 speed o/d. Good syncros and berrings in trans

A clunk stopping, accelerating and going into reverse is often caused by the drive shaft slip joint.

If the slip joint is in the transmission or transfer case you need to replace it. If its built into the drive shaft you need to replace the drive shaft. What makes the clunk is the slip joint binding as the shaft lengthens and shortens with axle wrap. To test grease it up real good.

The clunk will lessen or go away for a while.

idk a whole lot about limited slip but i think that big toothed flywheel looking thing on the ring gear means its limited slip and my rangers 7.5 does the same thing, drove me crazy didnt have the time to open it so i drove it daily and narrowed it down to the spider gears it seems to be a common 4x4 issue across all brands i think the limited slip puts extra stress on the bearings or something like that

[CrikeyMang]

@reap62 actually the that big tooth thing next to the ring gear should be a reluctor wheel for somethin. Speedo, Traction Control, ABS, etc...something of that nature. Not too familiar with these but its usually the same for make-to-make. The S shaped spring between the planatery gears is actually what tells you if its an open diff or limited slip. Or you can check by spinning the wheels like he did. If they spin in the opposite direction front and back than its open

Hey Man my 2004 GMC Sierra is doing the same thing, clunks when you stop, accelerate and reverse. what did you end up replacing?

[leeanator]

@russellhomeboy Have you tried pulling the drive shaft out and lubricating the spline which goes into the transmission? I did mine earlier today and it took care of the problem.

[CrikeyMang]

@russellhomeboy sounds like you have excessive play in your drivetrain. It could be a numbers if things. Worn ring & pinion, trans, u-joints. Check the u-joints first since its the easiest. If the vehical did alot of towing in its life it would be good to take it to a mechanic and check the rest of the stuff. He can provide more insight than I can over Youtube. Cheers! :D

clamp up that exhaust at the muffler section. Great video Ricco Stang covered it..Mustang boys we know all haha

[stevensf1504x41]

you have a worn out limited slip, both tires are suppose to turn in the same direction. rebuild kits are about 80 bucks

[DarkPrince013]

I also didn't know the 8.8 had an lsd option. I learn something new every day about these trucks.

[DarkPrince013]

Looks like its just tired. Shouldnt be much to have it rebuilt.

It Clunks

[RiccoStang]

LOL, That's funny, trying to clarify and forgot to delte the old post. lol

[RiccoStang]

Good video, Your clutch packs are worn out causing your axle gears to separate which causes your spiders to loosen up like that. It's an easy fix and can be done with carrier in place. Once you replace the clutch packs, the axle gears will close up the gap a bit and push up the spiders against the thruster washer. Your ready to rock and roll again

[RedneckSophisticate]

@RiccoStang That makes perfect sense now that I am looking back on it. However, given the benefit of a TrueTrac and the condition of the existing gears (chipped and cracked edges), I went with a new differential. I reused the housing, tubes, and 31-spline axle shafts. I put all new seals and bearings in it. I had to have Ford setup the ring and pinion gears because I wanted the crush sleeve and pinion bearings replaced and didn't want to buy gear depth gauge to do it myself.

@RedneckSophisticate Good for you, Now you got a kick ass diff. Enjoy!!

My 98 Dodge Ram 4x4 does the exact same thing as what your talking about, when you shift through gears it clunks, slow down it clunks, accelerate it clunks, ughhh soo annoying! My truck has 191,000 miles on it and I'm probably going to end up replacing the whole differential, good luck and if you find out what was wrong let me know.
