I just got my rear diff put back together from re doing the pinion nut and after the first test ride of about 45 to 50 mph on pavement for about 10 min and another 5 min at 25 mph in about 75 degree outside temperature I tested my rear diff with a IR Gage and got Temps from 95 to 103. I have nothing to compare these numbers 2 and was wondering if anyone has taken any temp readings of their diffs. Thnx for any input on this subject.
