AMC 20 Fix

I know basically nothing about rebuilding a rear end, so here's my question:

I mangled the carrier in my AMC 20 so I found a used one and bought it. It's all intact with the spider gears and ring gear still in it. How difficult is it just to put the whole thing in? Will there still be shimming and stuff that needs to be done? I checked a couple of shops and one gave me a price and suggested that it would have to be "set-up" and another pretty much just said it would be labor for sticking the thing in as it is. Which is right?

It's a crap shoot. The guy who set up my diffs does it for a living and said that most of the time they don't need any adjustments. He still uses this stuff that you put on the gears to "check the pattern". This tells him if the gears are meshing with the proper preload. I'd just try throwing it in and drive it to see if it howls. It won't hurt it to test drive it for a short period. I'd only do this if I didn't have much money wrapped up in it and I wasn't putting all new "expensive" parts in it. If I were putting a new R&P set with a master install kit, I'd have an expert do it.

You say your carrier is mangled. Assuming the pinion bearings and gear are ok, I would check agains the back of the ring gear with a dial indicator for run out. If its less than .003 or so, I would assume that the carrier is not warped and that it would be ok to take a ring and pinion backlash reading. Make a note of the reading. When you install the new carrier set the ring gear back to this same reading. I would install new bearings on the new carrier and preload them +.008" .
