I’ve read them all. Repack bearings every year and “I haven’t looked at them in 10 years.”

I have repacked every year for the last 7 years and found water on a couple.

Last week 30 miles from Rhinelander the whole shooting match goes off into the forest.

There was no visible grease on the spindle and a bearing was welded to it. Any ideas how this could have happened.

Has anyone experienced the same with about 3000 miles max on the trailer and meticulous repacking and inspection?

Axle is toast, hub and tire still rolling in the forest.

God blessed me that it didn’t happen in a crowd.

Location: Mt. Zion, IL		Grease compatibility, bearing preload, seal failure, water emulsification could all cause high heat that would do that.

If that meticulous, I would suspect different grease from one year to the rest. Grease is not grease and should be kept the same anytime possible. A good lithium complex grease with a 220 wt oil is what I would use. Mobil SHC 220 would be a great choice IMO. Most marine greases are lithium base. Lucas Red ‘N Tacky would be my 2nd choice if you’re buying at a mark or automotive store.

Location: Elk River, Minnesota		Was the castle nut still on the spindle? Which bearing seized...inner or outer?
