A few years ago, I upgraded my '97 w/35s Dana 30/35 to 5.13. Heard some diff noise the last 1-2 months but hoping it would hold until spring as I just use this mainly for my rentals to plow snow in winter and trailer a zero-turn in the summer.
Didn't last.
Spider gears/axles were fine. Had to rebuild with new ring and pinion and conventional fluid. Here's the main question: How hot is the diff supposed to feel after each run during the breaking in period?
I understand the break in period's supposed to last about 500 miles, 15-20 minutes each run, let cool 30-60 minutes, no highway speeds for a while, etc, etc. Each time I do a run, I check for seepage and touch the diff. The diff is BARELY warm to the touch. Yes, we are in the single digits right now, but I try to touch immediately after stopping - barely feels warm. Nowhere near the temp of the heater inside the cab.
Other questions: Wondering if it's supposed to get hotter ... and if it is, what temp should I shoot for? Where I cannot hold a palm to it for a few seconds? Will not getting to a certain temp keep the teeth from bedding in?
TIA
