Does anyone know what temperature range wheel bearings should be at during use after maybe 100 miles or so at 70 to 85 degree ambient temp? I will be measuring with an infrared heat detector at the exterior hub.

I'm looking for a range that is acceptable and temps that, above which, I should be concerned.

Temps can be all over the place depending on ambient conditions, axle model number and type, etc. so it's not possible to specify a precise number, best thing to do is compare all readings. For example if three are reasonably close together and one is significantly out of whack then you may have a problem.

X2 .... same with tire and brake temps

x3 and also in my opnion, if the inside of the hub is filled with grease, there is less room for an air pocket for cooling, that's why I always hand grease and not use the easy lube to grease wheel bearings, probably get alot of feed back on this one. Happy Campin...........Ron

I agree with you. To much grease will not let heat escape.

What I do when I check my temperatures is look for abnormality between front and rear wheels on the same side, such as tires, brakes, and bearings. I use an IF heat gun to measure the temps and look for temperatures that are abnormally high, 3 to 4 degrees of a delta T is ok in my opinion but 10 degrees would tell me something is wrong. I would than investigate to see what it is.
