Good to know. I like taking measurements of stuff when everything is running fine and then logging it so if it changes in the future I at least have a little advance notice that something is either behaving differently or, more likely, is about to go south on me. It didn't occur to me to stick a Thermax strip on the diff until this thread came out.
