'99 1500 4x4 front diff hatched ?
Front diff on my '99 1500 4x4 hatched. Cracked the case open. GM doesn't offer parts according to my GM dealer. I got the impression, because this is a 1500 and not a 2500 or 3500, the front diff case and axel tube size is unique to this vehicle series. Anyway, I found a shop that can reman one, but is looking for a case. No used ones around my area. Is there a difference in case's between the 1500's and the 2500's ? 3.42 gears, 8 bolt hubs - not going to be cheap either : (
8.50" & 9.25" GM IFS diff
There are three different GM ifs diff and I'm thinking the 8.50" (for 1500) and 9.25" (for 2500/3500)have the same mounting locations.
Suggest you check you RPO codes to determine exactly which IFS you have, doubtful a 1500 would come w/8600 lb 9.25" frt/ifs even in the diesel. An 8600 lb ifs diff has 14 bolts clamping the case halves together.
I've seen GM IFS diffs on pirate 4x4, and various search engines, and most bone yards what makes it tough is the gear selection 1999 8600 lb IFS diff came in only 4.10 or 3.73 period.
