Axle ?\'s on a 90 K5 My 10 bolt rear end has been giving me some pinion bearing whine here lately so I have been looking out for a heavier duty replacement. Came across a whole truck that doesn't run, motors shot. It's a 82 GMC crew-cab 3/4 ton 2wd with single rear wheels. It has a 14bff rear end. Wants $400 for the whole truck. Would that 14 work and is that a decent price? Mine has all that abs crap on it. I would have to retain my front 10 bolt for awhile.
