A year ago I lost two bearings (nearly at the same time) after extended travel (about 6 hours straight) in hot weather. Both axles were replaced with 6,000 lb. axles (upgraded from 4,000 #).
Last week, while traveling in extended hot weather, I lost another bearing. Each time I stop, I always feel the hubs for any heat build up. Nothing, until now. I pulled in to fuel up and checked my bearings. Found one smoking. Pulled away from the fuel line and the hub immediately broke and the wheel nearly fell off. What am I doing wrong? I do tend to drive a little fast (around 65-67 MPH), but not excessive.
I KNOW the axles were properly lubricated on both occasions (prior to failure). This recent bearing/axle has less than 3,000 miles on it, and is less than 1 year old.
What causes this?
