I have a 8.75 rear end with 430 gears, auburn carrier and Strange axles. It seems to be getting very hot Does anybody know the proper running temp of this set up. Thanks
I had a Dana 60 in an old Power Wagon I built. With 4.88's, Detroit Locker & 38" tall tires. On one trip down to Pismo Beach (about 4 hours at 70 mph) with less than a year old mineral gear oil; the rear end was so hot, I couldn't even get my hand to within a foot & a half of it because of the radiant heat coming off the rear cover.
A few weeks later, I swapped in some high quality synthetic before the (identical conditions) trip down, and I could put my hand right on the diff cover. It was amazing to me. I've run them ever since with the exception of the True Trac I got from Dr Diff. That traction device specifies non=synthetic gear oil.
