diff temps when driving (1 Viewer)

anyone ever measure diff temps after driving hwy speeds? I had the rear diff rebuilt with electric locker and today was the first time to drive it at hwy speeds, for about 3mi. after getting back I felt, then measured the rear diff temps and they were around 115F. also seem to have a growl from somewhere in the drive train. thanks.

When you say rebuild did you get new gears or just new carrier and bearings? When I use to rebuild diffs. I would take it up a grade under load and return to the shop and it will be in the 250* range, if you got new gears you should do a proper break in and no towing for a while.

Ring and pinion is original, that is they weren’t replaced. Bearings were replaced and a solid spacer was used. What parts exactly need breaking in? The bearings and/or ring and pinion? Thanks

ring and pinion if their replaced but since you reused the original theres no break in period
