When under light or hard acceleration, my rear end vibrates. My steering wheel doesnt shake or anything. Ive replaced my U-Joints in hopes of fixing the problem but no cigar.

I can tell its from the rear end, I just dont know what it is. Once I get up to speed it stops. It only happens when I accelerate from a stop light or sign. If Im already moving it doesnt have a problem unless Im doing around 5MPH.

I have taken it off road and done races and burnouts. Its all stock except a cold air intake.

I’d have the rear differential looked at.

I’m trying to do most of it myself. Its my first car and I won’t learn anything unless I do it myself. What would I be looking for? I know where the differential is, but do I drain it and check for metal shavings from the gears or what?
