Wheel bearings
What is so different with RV wheel bearings that they have to be packed at least every year or two. My truck and car does not require this yearly maintenance, why does the RV axles??

Heat is heat and the bearing temps will rise and fall from all of those reasons and unless you know the normal and acceptable temp range, and weather the measured temp is a fluctuation or constant temp, you just can’t make those claims…
Even the normal operating temp change with bearing size, load, speed, type of lubricants, and proper preload… I would think this is how they determine what bearing to use in mfg.…
I believe careful monitoring and observation of applications can sometimes reveal early warning signs of clearance and endplay-related problems, and is a good way to intervene before a permanent failure occurs… I don’t believe a temporary elevated temp is proof that a permanent or catastrophic failure has already occurred…
The big question remains what temp is too high and how accurate can we be at measuring it…
Even inaccurate but consistent measurements and help diagnose a problem…
A safe operating temp can be vastly different for the exact same bearing with different types of lubricants…
