Is this rearend compatible with mine?

    I have a 1/2 ton 1997 suburban 4x4 with a bad rearend(3.73). I have found a 1/2 ton 1998 Chevy pickup 4x4 with 4.3 V6 manual transmission. The owner says that the code in the glove box is a GT4, which means it is a 3.73. Will this work in my suburban? Is there any more info I need before I go this route?

    There is no reason it shouldn't work!!! They're the same platform, one just has a roof all the way!! Just to make sure, check the numbers on the housings!!

    I did see something that is a little different between the 2 rearends. The suburban has a sway bar and the pickup doesn't. I'm wondering if I can torch off the sway bar brackets off of my suburban rearend and weld them on the pickup rearend? Or completly take the sway bar out frum under the suburban?

    I would think welding your sway bars would be good, I dont think it would be a good idea to take off the sway bars, could get a little squirly!:lol:
