When was the last time you worked on your brakes? I had a loose caliper which caused my clunk.I get a clunk, but it sounds like my brakes and I'm pretty sure it is. I have AKG black diff mounts and an MFactory lsd. I have F30 brembo kit in back and its not 100% so I can't imagine it is anything else.
i got a performance shop to install the lid into the carrier and i installed the pumpkin into my car but i replaced all the bearings and provided all new shims, i was wondering if its the differential brace that is causing me to notice the clunk. Im going to remove it and see if i can still hear or feel the clunk. Also i don't hear or feel any whine or gear noise when accelerating or deceleratingDid you get a full pumpkin or install a new diff into your carrier? If the latter, did you have your shim/bearing done properly?
