Howdy y'all,

I'm new to the forum, so forgive me if this is in the wrong place.

I recently started hearing a squeak from my rear end only when in reverse, and it's only when I first start moving.

My baby (Annabelle) is a V6, but I recently swapped out my rear end with a GT Posi-track and replaced one of the drive shaft u-joints (it was insanely stiff when I pulled the drive shaft). I also just rebuilt my motor through Super Six Racing (.30 bore and a stroker kit). She is now a 4.3 liter V6 I'm also running a Monster tranny (auto).

Any ideas as to what this squeak could be? I'm thinking a bearing in the rear end. I was foolish enough to not completely rebuild it while I had it out...

 

Check your bushings in the upper and lower control arms as wel as the upper mounts on the rear axle

 

I guess I should have included that I have replaced every bushing on the car in the last year. I sounds like it is rotational, happening only when the car moves and directly related to how fast it moves in reverse. But it also disappears after I switch to drive.
