Dave, thanks for responding to my question. I have since changed all the bearings and races ( to timkin) from the oem equipment which was hyatt ( chinese made) . The bearings in the other three hubs looked ok. When michelin was pushing the change to singles no mention was made of increased bearing load because of offset. I am concerned this could happen again but don't know what to do as far as preventative maintenance.I will check with the axle reps. thanks again for the response, fuzz

2007 Mack Vision. Outer wheel bearing on left front drive axel came apart causing wheel,hub, and axel assembly to almost come off of truck. Bearing cage was destroyed and only the inner race was still on the spindle. We are running michelin super singles. Anyone else experienced this problem ?

2007 Mack vision came from the factory with duals but changed to super singles right away. at just shy of 400,000 mile had a left front drive axle outer bearing failure. bearing cage disintegrated causing tire, hub and axle to part way with the rest of the truck. axle had the required amount of oil. only the hub nuts kept the assembly on the truck until the driver got stopped. has anyone running singles had this problem ?
