Backing up binding noise
just got an 87 IROC. Rear disc, told it was posi (haven't had the chance to check on that).
When backing up there seems to be a noise that sounds like something is binding then releasing. Almost like a clunk noise upon rotation of the rear tires. Seems to mainly do it when turning the wheel (even slightly) and appears to go away if backing up straight.
is this normal (if it is a posi) or any idea what could be wrong
thanks

Re: Backing up binding noise
probably a good idea to pop off the diff cover and see what laying in it. sounds like something is broken in there.
or it could be brake related

thanks, planning on changing the rear fluid when it's not 110* out, this weather is brutal for car repair
