Well: Dave HM, I just took my 2 giant steps forward.....
Vulcaneer: I do check the hubs at every stop. I even have a 25 dollar Harbor Freight non-contact infrared thermometer that I up graded too in lou of my hand. Although I still do the "touch it" just to make sure.
MTPockets1: The sunny side on the wheels on my rig also increases the tire temp & pressure according to my TST system. Also if you brake hard entering a rest area or any pull off, the hubs do heat up also.
Michelle.S: Ahhhh - "the way back machine", back to the "Piston Head" days of the 60's. Remember now those muscle cars had the front wheel hub assembly as you say, and had front drum brakes as well unless you could afford a corvette. The brakes didn't last long & didn't stop all that well either. I remember changing a lot of brake shoes but not a lot of re-packing or changing bearings.
