I will have a hunt on this forum for the dimensions as I dont have a Haynes manual. If you could list them however, that would be handy. Thanks

These bearings look as though they have the 'spacer' built in - so you should just be able to assemble them (lots of Moly grease) and then tighten up the nut - with the thick washer under the nut of course. The inner races should butt together - and that should pre-set the running clearance - so the nut should not be setting the running clearance - merely clamping the inner races in place. Is that not what's happening ?

in theory yes should work fine!,i put hub on stub axel on radius arm making sure it's on properly,then the thrust washer and castle nut but even hand tight the split pin hole is already outbound the nut hence the split pin would do nothing?!?.my dads coming over tomorrow hopefully we'll get it sorted

I actually found that on mine also (rear wheels).
I wasnt sure if there was a washer under the castle nut, so I just put one in under the nut - and the castle nut is now functional in terms of locking on the pin.
All the internals seem fine... Wheel doesnt move around side to side, and spins nicely.
Was just an assumption I made... Am I wrong?

your right there should be a "thrust washer" under the castle nut,mine even with the correct washer and im still having problems.by what you just wrote wanago if i was you i'd obtain the correct washer for your hub as it is a specific size and thickness,also chamfered to the bearing face

completly contradicting my above post,looks like my only option is to add a second washer ontop of the thrust washer :lol: ,going to take my radius arms to andy at ml motorsport i think and get a 5th opinion.
