rearend whine?

[4.6boy]

i got a 02 gt with 373s a cobra tloc and moser axles. it was put to getter last yr and i never got any whine only a lil when going in revesr to fast. last week i replaces my shocks with blisteins and today i noticed a whine when doing sharp turns or figer 8s. what can this be? could the shocks have messed with the pinion angle?

It's not a pinion angle thing.

If the noise is definitely coming from the rear then you might want to suspect the limited slip differential itself. When you're turning is when the diff is slipping. THe noise may be coming from that although usually differentials chatter, not "whine." It may be as simple as replacing the oil and adding a bottle of friction modifier.

If the noise is only present on left or right turns (but not the other) you may have a bearing issue. If you're absolutely sure it's not a front wheel making the noise you may have a carrier bearing (which takes the side-loads from the rear axles) but this is pretty unlikely.

it does happen on both right and left turns. also if i put the car in n and roll down a hill it does not whine in a strat line. can a bad driveshaft ujoint whine like this? i changed the oil with 75w140 moblie rear diff oil and i bottle of motorcraft fm not even 2000 miles ago

If your car really is making noise only when cornering then I'll say it's not the driveshaft.

Are you hearing anything in a straight line when on the gas or off the gas?

i only hear a little whine( which i think comes from the trans} but it goes away after it shifts to 2nd gear also i got a squeaking noise coming form the rear supesion but everything else is fine
