Ok this is gonna sound stupid. Say there’s a fella, and said fella does a reverse burnout in 4.0 liter 2002 TJ. Hears a loud snapping/pop sound Said burnout ruins front diff and car has a rattling sound when reving in 1st, 2nd and reverse. Said fella fixes diff but jeep still has rattling sound. Any of y’all know what it is? For a friend of course. Cause what kind of idiot does a reverse burnout.
