Hi all,

I've been stripping down my rear subframe for overhaul and knew my Radius arms needed a refurb.
On inspection one is very bad, with the bush being worn away significantly on one side.

My question is whether this is salvageable for a refurb (there are several places online who offer exchange refurbed ones for old), or if Im better off not bothering to post it to those, and just buying a fully built new arm outright.

Pics attached. So far as I can tell, the wear hasn't begun to encroach on the arm itself.

Cheers, Peter

If they've worn through into the arm then generally that means they're too far gone to rebush with a normal kit. I'm sure if it was worthwhile you could have a machinist rebore and rebush the arm but it's likely more cost effective to just find rebuildable replacements.

Send them off exchange. They can change the bush to a bearing.

Are they bushes or are they massively damaged needle roller bearings.  They look like needle rollers to me.  If the outer casing of the needle roller bearing is still in place it should be possible to simply replace the bearing.

Thanks all. On closer inspection, yes its a horrendously worn needle bearing not a bush!
Hopefully it can be refurbed, no harm in sending it off to try

If you can borrow a long 13/16" reamer you can do it yourself for the price of a repair kit.

If you ream it don't you need an oversized version of whatever the bit that goes through the middle is called though?

No, the new bush is undersize when pushed in and the 13/16 reamer opens it out to the correct size for the standard spindle.
