During the recent flood in North Georgia / Metro Atlanta, My Dad's flatbed trailer was completely submerged under deep, muddy water for an extended time. The brakes, bearings, and electrical connections were damaged and / or corroded. This video shows how to clean and repack the wheel bearings. Hopefully, soon I'll upload the video of all I did to the front axle, trailer brakes, etc.
If you have disc brakes, repacking wheel bearings isn’t a difficult job. It’s just that you may not get the calipers back on right, which could cause your brakes to malfunction. If you have drum brakes, go right ahead and repack the bearings yourself. Follow these steps to repack the wheel bearings for drum brakes:
This is the set of steps I use to repack the wheel bearings with grease in our Dynatrac ProRock 60 front axle. The bearings, seals, and basic steps should be the same as a mid-90's Ford F350 front Dana 60 axle. Our axle has Warn Premium Locking Hubs, though other locking hubs should be similar in construction.
Clean up any other grease in the drum with solvent or brake cleaner. You should be able to clearly see the races in the hub. Like the bearings, if they show any sign of rust, discoloration, or pitting, they should be replaced. If you are replacing the wheel bearings, it’s simply a good idea to replace the races at the same time. To remove them, use a punch and hammer to tap them out of the drum.
