Checking bearings and brakes
Much discussion and varied opinions on how often to open up the drums and check the bearings. I am of the group that says to open and inspect. I do not use the Dexter EZLube system
I typically do an inspection every spring. Never found an issue on any inspection and ALMOST decided to wait until next year.
Today I started on the bearings and brakes.
First set in good shape, clean and not over greased.
Second wheel. Outer cone had spalling on the rollers. Prior to removing I heard a growl when spinning.
Third set. Both cones had spalling and a few chips. This wheel made NO noise when spinning.
Fourth wheel. When I removed the hub the brake magnet fell down. Upon inspection I found the bent section of the cam where the magnet and spring mounted to have broken off. No damage to the drum.
So. Two wheels with damaged cones and only one made noise. The wheel with the broken level made no noise when spinning. No grease leakage behind the seals.
New brake assembly ordered. For 10 years I have kept a 2 sets of bearings in my camper. Never needed them until today.
