Problem:
Bearing failures on tag axle.
1st failure occurred at approximately 10,500 miles. Left tag axle wheel bearing failed while driving down interstate 10 at approximately 72 mph.
After installing new bearings, had the right side tag axle wheel removed and repacked.
2nd failure occurred at approximately 19,000 miles. Right tag axle wheel bearing failed.
Exact cause was not determined, however, after weighing just the tag axle it was found to be approximately 1 ton over design weight.
After removing as much "stuff" as possible, the tag axle was still over weight by almost the same amount.
