diffs probably dead. you can get a nice 600grit sand paper and sand the large diff plates smooth again. i replaced the trust bearing parts with a set of yokomo parts and they fit and work perfectly. remember to lube all that stuff. all the balls are suppose to be smooth. i use and hear alot of people like to use Team Associated diff lube. the black kind for the trust bearings and the slealth lube for the rest. i just use steath (the clear stuff) all over and it works fine.

hope that helps
