So I blew the spiders and axle gears in my suburban while a few hundred miles from home. It's a 1/2 ton with a 10 bolt and 3.73s. Limped it to a buddy's house in 4x4 and have a place to work on it. Got new gears and a pin for it, was about to throw them in and call it a day when I noticed the carrier was smashed up where the spiders go. I've got a carrier from another car laying around that I should be able to bolt my ring gear to and toss right in. Only problem is that I don't know the first thing about shimming a rear and from what I read it looks like I don't have a lot of the tools required to do so anyway. I'm in a real bind right now, I've been living out of my truck and everything I own is in the back. I need to get back up from CT to NH for a job interview soon and I have less than $100 to my name so buying a whole new rear or paying a shop to fix it is out of the question . I'm seriously considering just throwing it together using the same shims that are in there now and hoping for the best. What are the odds that it won't blow up on me if I do that? Has anyone here ever successfully changed a carrier without shimming it? Is it common to be able to do that? I understand that it is not the right way to do it but I'm kind of out of options and running out of time. Am I just screwed or could it work?
