first off ou did not mention if they are 12bolts, im sure they did
not put a 10bolt in a suburban or a 4x4, 12 bolts are interchangable,
but you will need only gaskets if your bearings are good, your
yokes should match up and should not have a problem, but, i would
search on internet on both vehicles and get all the info on the
rears and drive shaft length and your splines match, your gear
ratios might be different as well, do the research
