after a few half *** 360's, burnouts and 8's my rear-end started to make a sound like a broken cv joint. It was doing some great drifting and donuts but last night it would only do big circle burnouts instead of the usual smoky small circles?? It still burnsout with both wheels and drives straight but every time I turn it sounds like something is clicking. I jacked the rear up and turn wheels by hand forward and backward and both wheels turn simultanously with no noises. If a buddy holds one and i turn the other I get a loud screeching sound from the ends of the diff, no noises out the 3rd member though. I suspect the wheel bearings, wont know till I tear it down.............any suggestions or opinions.



80 with 85 gsl-se rearend swap.

 

pull the pumpkin and look.



i broke a ring gear on mine, made loud knocking noises

 

you might have gotten the spiders too hot and they could've seized on the pinion shaft. Drain the diff and do a visual inspection
