I was wondering how many of you check your hubs for overheating when you stop and get gas or pit stops. While driving home from Branson (232 miles total one way) I stopped for gas and two hubs were kind of hot (different axles) but touchable and two were cold. I took the camper yesterday to get the bearings checked. I just had them packed last year and I told the service writer that the technician may have tightened two of them down to tight.Since repacking last year I have only driven 1200 miles and I don't consider that excessive miles.I would assume while driving they should all be close to same temperature.

Warm (you can keep your hand on it) is acceptable.

Yes, they should be close although the side receiving the sun will be elevated. I use an infrared temp gun from Harbor Freight and it makes checking temps very easy. They are very reasonable there.

Another thing that can affect the temperature is brake adjustment. You have just made a stop and if some brakes are tighter than others they will generate more heat.

X2 on brake adjustment. I once adjusted my brakes after a break in period, and 200 miles down the road one hub was 50 degrees hotter than the other 3. Had the tool with me so laid under the trailer at the rest stop and loosened it slightly. Problem solved. ALKO axle support (back before being bought by Dexter) told me that hubs could run as high as 300 degrees without a problem, although that seems high to me.

I touch each hub on every stop’s walk around. Quick, easy.

Yes I think excessive heat (300) would affect bearing failure.

I usually check bearings during stops cause my bladder is 2 hours or less range and typically they stay cool.

please show picture of temp gun you use and is it accurate.
