The sound coming from under the middle to rear of the car when the wheel is all the way to the left or right and rolling. The faster I go when the wheel is cranked the faster the clunks. Any one know why this is? I also might be a little behind on changing out my diff fluid. Could this be it? Thanks so much guys/gals.

And it only happens when your wheel is turned all the way? What about when the wheel is turned 180 at higher speeds?

Also try jacking the car up in the back and spinning one of the back wheels, any abnormal happen then?

While it's up there check your axles and cv joints (i think).

I don't know a whole lot, but in my limited experience I havn't head a diff "clunk" when the wheel is turned all the way, but then again my previous exp with diff's (I have only owned the S for a couple months) was with the viscous coupling type.

During full lock steering situations your diff has to work very hard.
The difference in rotational speed of the wheels is "telling" the diff one wheel is slipping and it should "move" to torque to the wheel that doesn't slip by "pressing" the 2 axles together, making them 1.
(remember that a single axle (no diff) is hard to make turns with)
The LSD, or limited slip part (between the axles) makes it possible to go around turns.
But none of the wheels acutally slip and that is "telling" the diff it should "relax".


It is normal for a Torsen LSD to make some noise during those situations.

I'm not sure they are supposed to be cluncks.
It could be - IMO! - that the pressure is "releaved" in steps (or cluncks).

Change the diff fluid, look how many and how big the shaving on the magnetic drain plug are and see what it does.

You could do the diff test :
- jack up rear on jack stands - both wheels of the ground, make sure its safe.
- put car in first gear
- turn one wheel clockwise => the other wheel should turn the other way
- perform on both wheels.
- listen for noises, etc.

Let us know what you find.

I wish I could do that right now and give you back the results but I am currently deployed. When I get back I will do all this. What should I be looking for in the axles and cv joints? I know this is a noob question but I learn quickly so I will only have to ask once I hope....

Play, torn-up rubber boots, noise while turning.
Are you lowered?

Nope stock height. I will look for that, thx!!!
