Pins are worn where the helper spring lives. Which way do the pins press in / out?

There's a circlip on the stub axle (helper spring end) so at a guess i would say it is press out from the bearing end and press in from the helper spring end.
I imagine the circlip acts as a stop.
Let me know how you get on because I need to do that same job on some wet arms and dry ones.

They are pushed out as InimiaD says from the wheel bearing end and can be
a pig to shift sometimes!

Can you get replacement middles?

they turn up on ebay often - there was a pair last week i think.
you can also either press them out and drill and thread them and make an insert to fix them (you can even do this without removing them but its harder to do obviously)
