Hello everyone...it's time I got more active on here. I have been a bit of a troll I guess but I have learned so much from this site! Thank you all for your knowledge! I have had a sort of grinding/howling sound coming from the rear end of my Stang for a while now and it bothers me. The sound is present regardless of the gear I am in and seems to increase with RPM's. A buddy of mine said it might be the carrier bearings? I have done plenty of other mods but maybe it is time to get those 4.10's or 3.73's! Any suggestions? Thanks!
