My car is on the raps right now and they have called me to say the rose jointed bearings I bought from Autosport bearings place don't fit.Any special technique to getting them in?They say won't go through the hub.

The bearings don't go through the hub mate. The tapered spindle from the bumpsteer kit (if that's what's being fitted) go into the hub.

Unless I've got my wires mixed with what your on about?

The bearings fit into a separate spindle as Ollie. the bearings on their own won't do anything.

I've been to the garage to check and the new bearings are too big for the powerstation sleeves.The powerstation bumpsteer kit look s like it uses m12 whereas the new bearings are m14 for GL on the diagram below.Also where the stud on the hub goes through the eye of the rosejoint D on the diagram, that is also too small so there is play against the bearing so would be undriveable.
Its not the fault of autosport, they sent me exactly what I ordered its just they don't match up to the powerstation sleeves.

Was the stud coming off the hub into the hole D above also 14mm on your kit, did you use a shim to space out the m12(I think) stud on the hub to 14mm into the rosejoint hole?Do you have any of the sleeves left over at all?
Ideally I would buy new sleeves with an m14 thread, some shims for the hub stud and it would all work fine.I'd prefer to keep the bearings I have than swap to smaller ones.

Fastguy, is that a new stud on the hub too?Mine doesn't look quite like that.I guess that the height the stud puts the rosejoint at is going to affect the bumpsteer.

I've also considered retapping the sleeves I have.How tricky is it to tap out a new thread from m12 to m14?

i had this exact problem. Had to get them machined out to fit the new bearing. The difference in the quality of the new bearings to the old kit is like night and day. No wonder the origional kit wore out so quickly when you look at them side by side

That's Kirkos' kit. So it probably is abit different to the others.

As for tapping I guess it depends how hard the metal is. I suppose you'd need to drill the hole out then retap it. Kirko may be able to advise. He did have some bits left, but I don't know if he sold them off.

Yeah come on Kirko, log on! :p I have told the garage to take the sleeves off and take them to an engineers to have them retapped tomorrow but if I can get some new sleeves I'd rather do that.
