A well spent $35 for me was to go to Radio Shack and get a IR thermometer. I just walk around the truck and trailer and point it at tires and hubs. If I see one with a big reading difference from the others I check it out.

 

that's a good idea. i would have never thought an IR thermometer was that cheap. might have to get one now since i can't use the dealerships anymore. those work good for checking out misfires too by checking temp differences at the exhaust ports.

 

Damn that is cheap I figured they $200 I guess thats only is they have Snap On on them. I will get one soon even though the trailer is sold I always wanted one.
