I put my new Auburn L/S in today. Everything went together pretty well. I set my backlash up at .005" and checked my ring and pinion tooth pattern. It was riding nearly dead center of the teeth on both the drive and coast side.I put everything back together and went and drove it. I only have a slight whineon decel at about 50m.p.h. I drove it about 10 miles between 60 and 70 mph. When I got home I checked the temp of the diff pan and it was at about 135 degrees F. I have never checked differential temp and I was wondering if this is about right. The temp outside is 85 F. Other than that everything seems ok. I would again like to thank everyone on here because y'all have been a wealth of infomation and help..

 

im no expert but that sounds about right

 

It's fine.Conventional dinooil won't break down until 200* or so. Syn can go a little higher.
