Hi all i have a 04 sti type uk and recently as im reversing off the drive im getting a strange crunching/grinding noise from the rear and then when i pull away forwards there is sometimes a little pop at the rear.
Ive been told that it could just be pick up in the diff but im not to sure, could anyone give me any advice cheers.

i occasionally get a pop type noise when pulling away, almost as if it has been standing for too long and has seized. although i know this is not the case. advice then is just to keep an eye on it, obviously if it was to get any worse get it in to get sorted. if under warranty, get it in asap.
