The rear 2-wd rear end has been swapped out with a 4-wd rear end to get the wider track width. The rear end came out of a 2000 Oldsmobile Bravada with the production codes GT4 G80. It's a disk brake, 3:73 gear with limited slip. I went ahead and removed the cover and drained it, washed it out with brake clean, and installed new axle seals, and filled it with fresh gear oil. I installed new dust shields, rotors, and pads.
I’ve also learned that a Ford 8.8 in. rear end which is common in Explores has a track width very close to a 4-wd S10 rear end. They even have nearly the same spring saddle width and they are practically a drop in other than needing some conversion u-joints. I’ve seen this conversion discussed on several S10 forums. If my rear end doesn’t hold up in the long run, I’ll probably swap it out to a stronger Ford 8.8 in.
The rear end for now has 3 in. drop blocks. Beware, don’t mess with the Beltech drop block set or other manufactures drop block sets for the S10, they don’t come with the right u-bolts 1) they are too wide and 2) they are a smaller diameter rod than stock. I had u-bolts bent at a leaf spring shop of the correct diameter and dimensions. Jagsthatrun.com are the only one that I know of that include the correct size u-bolts, which I wish I knew beforehand.
