Hey guys, I noticed today that my right rear tire is worn down a lot more then the left rear tire. I have done some research and think it might be axel nut needs tighen to resolve this problem. Alignment was done 3 months ago.
Also if the axel nut does need tighened where is it at? I read it needs 220 ft tq?
Thanks

UPDATE: I tighened axle nuts some and problem is still here. I am now thinking CJ joint or wheel bearing. The car also shakes (NOT vibrates) at higher speeds on highway. The shaking will come and go within seconds of another. Is there anyway of knowing which it is or do I have to take a shot in the dark here?

search for 'axle nut TSB' to all the info on that. The axle nut issue manifests as a distinct POP when changing directions, I've never heard of tire wear issues from it.

What kind of disparity in wear are you seeing? It's not unusual for the torsen to allow more slip on one side - my right rear usually wears 1/32nd faster than the left. It could also come down to driving habits - do you do more left hand turns that would abuse the right rear more? Or, the toe could be off on that one tire, and burn it down a lot faster.

A lot can change with alignment 3 months after it has been done. sounds like your toe is out of whack

Either alignment is out or your wheel bearing is going out like mine did.

My right tire was wearing quick and alignment was in spec, turns out to be the wheel bearing which started making a noise at slow speeds and eventually horrible loud noise at slow speeds...it got worse and worse with time...but the sooner you catch it the sooner you can fix it.

Get alignment checked first, then jack up the right side and see if there is any play in the wheel itself.

Hope it helps.
Thanks.

If the wheel bearing was causing rapid tire wear you wouldn't be able to hear the engine over the bearing noise.

Tightening the axle nut isn't going to fix a tire wear problem.

im so happy i came across this thread. I just lowered my car a while ago and was wondering why only the right rear had about less than a 1/4 inch more gap than the opposing side. makes sense.

Did you have a big difference in tire pressure? If you were running low tire pressure in one of your rear tires, it could reduce the effective tire diameter causing one tire to wear faster over time. It would also cause your car to pull to one side when you accelerate.

If you drive solo on rough pavement a lot, like I do, the result will be slightly more net slippage on the right side(driver's weight slightly improves traction on left side). It does not take much to show up as increase wear. I improved but did not cure the problem by running 33 psi driver side and 30 psi pax side.

I've been tempted to swap/re-mount the tires at the 1/2 way point but never seem to get around to it.

Isn't it because the stock diff. is a "peg leg" and there is consistently more power going to that wheel than the other?
