Hi there. I am new to boating, having just bought a 14 foot day boat
and trailer last weekend. I have been checking over the trailer and I
dismantled the wheel bearings to check them. They are a pair of tapered
roller bearings, fitted to a hub with 'HG 505' marked on it. The thing
is, the hub has about 2mm slack when I tighten the hub nut fully. I
would have thought that there would be less play. Is the hub assembly
worn?
Any ideas on this would be much appreciated.

Thanks Davy M.
