I changed my fluid this past weekend, and got a nice temp drop. That got me to thinking - what are typical rear diff temps? I know it's not the most accurate for actual fluid temp, but I used an IR temp gun to measure the temp of the rear cover to give me an approximation. It was in the 140-145 range after a 2 hour, 75 MPH highway cruise.
So, what are you all seeing for your rear diff temps?
