I have a 5x10' utility trailer which I overloaded foolishly the other day,
carrying fill dirt. We emptied it, and the next time I pulled the trailer,
empty, it didn't pull correctly. It hopped, chirped, and went 'tick tick tick'.

Home it came and today I pulled off the hubs, expecting to see a cracked inner
bearing race. I actually don't see any damage at all, but now that I've got them
off, I may as well replace the bearings and seals.

I'm having trouble pulling the inner bearing races. Is there a trick?

When I packed or replaced boat trailer bearings every spring, I turned
an aluminum mandrel to press or pound out the inner race from the
inboard side of the hub. Still have the mandrel in my toolbox. I
used aluminum because I didn't have any brass of large enough
diameter.

Pounding with a brass drift works too, moving the drift after each
hit. A full-circumference mandrel and press works best because it
eliminates any tilting of the race.
