Brake replacement, great results only to find out bearing is going out, yuk!

Had brake shoes and magnets with backing plate changed today, was cheaper to buy as a complete set up. They were replaced and still had minimal braking. Found some faulty wiring and repaired same. After drive home checked heat on bearings and found one neverlube bearing running 50% hotter than others. All bearings were checked visually but not measured for slack or wear. Oh well break out the pocket book! Very glad I found it now rather than later.

Firm believer in heat guns, $10-15 infered gun saved possible hundreds or more plus the danger of wheel falling off.

Seems like there have been a rash of bearing failures

Good catch. A friend's 5er lost a wheel because of a Lippert never lube failure. We spent weeks repairing the 5er doing sheetmetal replacement and fiberglass repair. The wheel nearly tore the rear cap off and put a hole in it. Some structural repair was also needed along with wiring.

We had 1 go bad in Texas. A quick Google search found a Dexter parts dealer that had the bearing in stock and a press capable of doing the swap. Bearing cartridge was in the $170 range. Pressing was free.

From what the guy told me is that there is "Play" already set in the bearing. But he never said how much was normal, or excessive. They did say that doing tight 90* turns where the wheels were dragging or not having the axles un-torqued when parked put stress on the bearing cartridges.

For instance, you back into a hard 90* site and don't have enough room or time straighten the rig out completely. There is still sidewall stress on the tires, rims, and bearings. As the tires and bearing cool they contract putting more force on the cartridge.

I also use a temperature gun and repack/inspect bearings every 10k miles. I can't remember ever having a trailer bearing fail and I have hauled a lot of trailers in the past. I have replaced many vehicle bearing hubs due to bearing failures. I prefer/insist on a grease type bearing over a hub assembly any day.

Had one never-lube failure. Found it by jacking up and checking play on each wheel. The bad one had a huge amount of play. The funny thing was that it wasn't the bearing that failed, but the hole in the hub that the bearing was pressed into had worn excessively. The bearing itself was still tight and smooth. We had Kodiak disc brakes installed by Mor-ryde with the integrated hub/disc. Don't know if it was a defective hub from the get go or what exactly happened. I now carry a spare hub/bearing/rotor assy. and check play a couple of times a year as well as temps while towing. Kodiak supplies the bearings and hub/rotor assys.
