Hi,
I am currently replacing the swivel bearings on the front hub of my Rocky
how can i adjust the shims on the swivel bearings to get the axel in the right position for the inner seal?
I tried downloading the aussie rocky service manual but the link is dead.
any help appreciated

Phil, I've got the manual on Cd and can probably Email or else upload the relevant section onto the Internet and you can download it?

I thought the shims only set the pre-load on the swivel bearings?
I would have thought there would be enough slop in the cv's to negate any possitioning effect on the axle?
If i'm wrong please correct me. My passenger side seal has been leaking for ages despite replacing it. I just thought the cv was worn.
Cheers.

shims are for the preload on the bearings
Pedders sell offset bearings too for camber ajustment

Thanks guys for your help. The manual was good except my Rocky is an F85 model and has no needle bearing on the hub. It has a brass bush instead which is now a rather loose fit on the axle. (pictured)

Re the shims they do adjust the swivel bearing preload but my suspicion is that they also control the height of the axle (shims can be put in top or bottom) and therefore the centralising of it on the axle tube seal. If the axle is too high the seal will be distorted and leak diff oil into the hub. This may be your problem Tabrocky

Yeah, I see your point Phil, but I'm still not convinced thats your problem.
The brass bush is the same on the F75. Im pretty sure landcruisers even use the same type of bush. I wouldn't be to worried about the slop in it unless it's significant. I don't think they were ever very tight to begin with.
Mine still leaks a little but not enough to worry about it. I've seen so many other vehicles do it and it always seems to happen on the longside axle.
My guess is because of it's length and lack of support near the hub.
I always put it down to a worn CV. It doesnt matter how well you support the outer end after the CV. If the CV's worn the axel will flop around hence causing the oil leak.
I'll be intrested to hear if the shims do sort your problem tho'.
Cheers.
