Seen several posts in the past about correct way to adjust bearings.

My usual way is to tighten up until no play, but wheel spins freely.

I found the 'official' way today ... while buying some new hubs.

Remove cap
Remove split pin
remove castellated nut & thrust washer
remove stub axle & bearing assembly as complete unit
(Rear bearing will usually stay on stub axle)
-change or clean up parts
coat all with new grease ... waterproof if for boats.
push bearing cones into the cups until fully seated
(cones always point into centre of hub)
push new grease seals into it's bore where required
Slide hub onto stub axle
Fit thrust washer and tighten castellated nut to 20Lbft
Slacken off 1/4 turn
*** this now provides 1mm correct end float
Insert new split pin & splay
pack with grease, replace plastic cup

Taper roller bearings - Hi there, I bought a 14 foot boat with trailer. The problem I have is that the hubs had about 2-3mm 'float' when the hub nut was tightened up fully. I felt that this was too much. I have now fitted new bearings and I need to know how much play to..
