Warm Differential??
I pulled a code this week, a 452/PSOM/VSS, no big deal, cause the truck is running good and I haven't had any OD lights, bouncing speedos, or harsh shifting.
I cleared the code and will check the codes in a few days.
I searched FTE and read a few topics about the rear-end speed sensor and speedo PSOM and afterwards decided to go outside and check out the wiring and have a look at the rear. While inspecting the rear I felt that the rear housing was very warm to the touch, I had driven the truck 15 miles and parked it one hour before the inspection. Strange thing is, the brake drums were cold, and the axle was cold.
How much heat is normally generated by the rear gears, should the rear be warm after a 15 mile (no load) drive, and parked for one hour????
BTW, it is a 92 Long bed XLT with 3.08's and stock wheels pushed by an E4OD/4.9L
