NEW GEARS...Front diff temperature vs rear????? (1 Viewer)

[Chained Rock]

Just re geared the 80 to 4.88's and installed front and rear arbs.... I'm in the break-in phase and the front diff seams to be running noticeably warmer than the rear... to the touch it is much cooler than the t-case after 15 ro 20 minute drives... my question is does anyone have a temperature that is "normal" for diffs and t-case to run?

I don't have any numbers, but remember the front diff is sitting right under a big hot motor. Radiant heat is almost always going to keep it warmer than the rear. A 10 to 15 degree difference seems like it could be pretty normal.

160-180F isn't abnormal
