Hey all,

Whilst removing the rear hubs to fit some longer wheel studs I found play in the o/s one, there is about a 1/2" movement forwards and backwards (non side to side) and you can see the driveshaft moving too. I have tried tightening the slack up on the hub nut buts its fully tight and doesnt affect it.

Is this just worn bearings? or something more severe, I would of thought you should be able to lock the hub up tight using the hub/castle nut but it doesnt. Can/do they need shimming?

Also looking on the exploded diagrams, theres a spacer in the middle of the bearings which looks like what the outer hub tightens too, are these standard sizes etc?

Still a newbie noob with the aircooled variety so appologies for all the questions.

All of the axial (in/out) motion is controlled by the inner (ball)
bearing. That bearing is locked in place by the Circlip.
When you tighten the castle nut, the hub is drawn against the
spacer and the ball bearing inner race. The ball bearing and the
stub axle and hub now act as a solid lump together.

Radial motion (fore/aft) is controlled mainly by the outer (roller)
bearing. This bearing normally has a little play in it, but 1/2"
is excessive. Tightening the nut has no effect on this.
Hopefully it is only the bearing which has worn to produce this play
and not the housing or the stub axle...
