Any mechanical types around who can offer some insight? I've got an 84 GMC S-15. I'm told the rear end has gone kaput, and I'm trying to figure out what it will cost me. I'm not terribly mechanical, but if the job is not to difficult, and the savings are signifigant, I would consider giving it a go myself. So can anyone give me a ballpark what it might cost new to have the job done vs. buying one from a wrecking yard and doing it myself? Thanks.
