okay i opened up the cover today and i found a piece laying in the bottom its almost half moon shape i checked my manual at the break down and it looks like its the thrust washer is is that hard to replace i have the trac lok diff. im pretty sure that is prob what the problem has been that washer was getting weak and finally just broke.

 

It's not the c-clip?

 

no this is wide and flat those are a full C shape and thick. this is like 1/4 of full circle shape. and only about 1/8" thick im pretty sure its the thrust washer i havent tore apart the trac lok yet to see i gotta wait cause no one has one in stock

 

I have the same problem. Did you have any problems with your repair? I've got mine taken apart, but I was wondering if It would behoove me to change the bearings now too?
