I need some help to know what's wrong with my 1997zj rear differential parts
I would appreciate some help to understand whats wrong with my rear differential, it have a little noise and the mechanic said that I should change the fluid, so I have done a fluid change but the noise is still there, less noise but still there, while I was changing the fluid I have made some pictures and Im guessing but must be something wrong because I think the noise comes from the wear part as you can see on the picture bellow, please can someone give some advise about that and how bad is it? what is the problem or what I should replace?
thank you very much !!
