Wheel Bearing Temps & Test Drive
I have a 2010 KZ RV CL164 and repacked the bearings this spring (single 3500# axle). I have done bearings before (on a small pop-up) but never took the temp with and IR temperature gun. Here is wha...

Depends on how fast you were going. If you were at 65 mph for a few hours on the road, they would be hotter.
On our trip last weekend, it was in the 90's outside, and the tire temps on my TPMS were 117-123 depending on wheel, so the bearing was probably hotter. I was running at 70 mph.
I don't think bearings get "up to temp" like an engine does, since there is nothing regulating temp except grease and airflow. Overall bearing temp is a function of speed, duration and ambient temps. Assuming all is working weel, the bearings shouldn't get hotter than 165 or so.
