Ok so I have a TJ and was told I need new ujoints (already got last Saturday for my front axels) they also said I need to replace my dust covers and seals as well as axel fluid? while I'm at it but not sure what parts I need ! I was quoted $400 for a machanic to do it but that is absolutely out of my price range so I'm going to do it myself!! But I need help with the names of the exact parts I need !! And what fluid is good? Can someone help me suggestions and advice is greatly appreciated!!! Thank you!!
