Summer is approaching and its time to dust off the trailer and carry out some
basic maintenance, especially to wheel bearings.
Boat trailer wheels are often submersed and require particular attention.
Its better to check, repack and/or replace wheel bearings before you go on
holidays rather than losing a wheel on the highway.
To begin, jack up your trailer and check for any play in the bearing. Turn the
wheel and listen for any grumbling sounds. Remove hub and hubcap. Pull out the
split pin, take off the nut and pull the hub gently forward and back to expose
the washer and bearing separate for cleaning.
Take off hub. If re-using oil seal, remove it gently. Remove grease and
de-grease. Replace bearings and racers. Cover bearing rollers and hubs with
grease. Reassemble, pack bearing with grease and replace tyre.
