good idea hydra... ill have to do that this weekend... since it only makes the noise when accelerating and while in drive where all would you suggest checking...

 

I do not recommend doing this very fast because the wheels will spin in opposite directions not to mention how dangerous this is. But I would be checking the input and output bearings.

 

whine when accelerating could be pinion trust bearing in differential.

 

well im almost posative it was the fact that we didn't notice i had a limited slip when we redid the rear axle bearings. the diff was filled with just diff fluid, no friction modifier. added the modifier and i think the noise is gone.

 

Check out this thread on how I was properly informed on what to look for.
