Ok guys, I need your expertise: Because of a bad VC unit, I'm going to bite the bullet and have my transfer case replaced (after much thought and deliberation -- going to put money into my 80 instead of purchasing a used 100). Figuring it's going to cost me an arm and a leg (planning to do work through dealer), I want to get everything else up to spec too. Several minor rear differential-related clunks also exist so I am going to try to have everything clunk-free when all is said and done. Can you give me some suggestions about what I should have serviced in order provide clunk-free driving? (aside from the standard transmission backlash of course) Is there such a thing as a rear diff overhaul? How bout axle service? Or bearing replacement if needed? I'm somewhat mechanically-challenged, so I don't know what I don't know and if I'm going to spend some money to give my LC a few more years, I'd like to do it right. Thanks for the help! kent allen 1994 80 101k mi.
