Wheel bearing problem

[southwindsfarm99]

We have a 2012 38 BR. In the past 3 years we've had 3 wheel bearing failures which resulted in 3 new axles. They have been greased and maintained professionally and regularly. The axles loaded are 13000lb on 2×7000lbs axles. We do not overload and balance load as evenly as possible. Tires are Michelin 265/16 LT.

I have been hauling trailers for 15 years without any issues until this unit. Hauled a DRV roughly the same weight for 10 years with no problems. Any suggestions?

loose bearing last a long time ,if they are installed to tight they fail. If the grease they get a good hand full of high quality grease and repacked every year or so they don't need any other work . Don't give them any extra grease during the year , chances are its just going to get on your brakes.

"Professionally & regularly" doesn't necessarily mean correctly!
If they just squirted a couple squirts into the EZ lube system isn't the correct method if I were paying a "professional" to pack the bearings.
How did they say they packed them?
Did you witness how they may have done them?

They were removed and packed by hand. One bearing was already bad after one year from factory new axle. The bearings were tightened and backed off for the cutter pin. On the last new axle the factory didn't use the proper cotter pun on the newest axle.
