alright so ive been doing a few burnouts (stock) last night i started off on the brakes got up to 3rd let the brake started turning it dropped out to one wheel an speedo went over 200kmh and sounded terrible so i stopped now i get clunking from right rear and the wheel even jerks like its catching on something, at speed its fine only have the issue while turning at low speed, cant hear humming while cruising along or anything.
was quite nasty staright afterwards and parking it but when i got in to drive home just one clunk in reverse drove 30km home no issues reversed in at home no issues,
any ideas where i should start? no holes in diff housing no oil leaking nothing looks out of place under there

One wheel spinning, you probably grenaded your spider gears. Drain the differential oil and look for chunks. Pro-tip: remove the fill plug first to be sure you can before dropping the oil. Pro-tip 2: don't do burnouts.

thanks ill do that tip #2 i cant abide by sorry 😁

Hard play - cost is broken parts. Next time make a vid.

But do take a picture of the lube, and once you've popped the diffy cover to look at the chunks.

boostjunkie

will do and yes i do realize things will break if i be an idiot, i do drag racing and some fun track time and since i run xhp skids are alot more fun the tranny is soo much better than stock

Maybe you got lucky and spared the diff, but if you're getting the kind of noises you describe, something is wrong. Fluid looks like a change was in order, so not a waste of money.

Do the CV axles look OK? Popping and such could be a damaged CV too.

visualy and i tried rotating them for any play they seem tight no slack or clunking i jacked up one side pit it in neutral and let the e brake off and i can rotate thdrivers side rear but not easily and it seems to jam and require alot if force to unjam the rotates a bit almost freely then jams again fluid was done at 120,000ks at 150,000ks now

My main question here is how do you burn out? I’ve been trying to do it on my 08 550i but whenever I try, the car cuts the gas and it does nothing. Like legit, it revs up and the wheel spins for a quick second and then it’s as if I let off the gas but i haven’t taken my foot off the pedal. This is with all traction control off.
