Attention: TDR Forum Junkies 
For years I've carried a infrared temperature gun... . On a cool day the tires are always under 95*, and the wheel hubs are always under 90* with the tires on the truck under 90*... . on a hot day the tires might go to as high as 115* and the wheel bearings maybe 110*, all checked when I've just pulled into a rest stop. . I've just started to test the ujoints on the rear drive line but don't have a standard for that...
I'd expect to see a sharp rise in temperature when there is a low tire, or tire with a separation... . hot wheel bearing... etc...
I now pull a 06 trailer that weighs about 15K loaded and have to date pulled the bearings down for inspection and packing once, about 2 years ago... as long as the temperature remains down I'm not going to do much... remember that front wheel bearings on cars used to go 50K miles between brake changes when they were rear wheel drive...
A quick check 2-3 times a day when on the road sure tells a lot... Just my thoughts on this... . Hope it helps...
