How do everyone! Now, I have a knackered stub / pin on a rear radius arm, when trying to remove the stud nut, it all went a bit wrong, so now having to replace the stub. So, how do I get the stub out of the radius arm? I have been told by Mini Sport and I quote "The Stub shafts are pressed in from the back but there is a circlip holding the shaft in and will need to be removed before knocking the old one out" which is fair enough, but can they be knocked out, or do they as I have also been told, will need to be pressed out by a, well a press!!! Any assistance or advice from someone who has had this issue would be greatly appreciated, many thanks in advance

they could be drifted out, but this would reqire either top bodging or a propper tool, if it were to be drifting them out i wouldnt do it unless i had a correctly sized tool (teehee)
best way would be to press them out, but with something with the correct outer diameter to the shaft
your local garage should have a press and should be able to do this sort of thing:)

The circlip stops the shaft from pulling right through. You can probably press it out backwards, the reverse to the way it went in, if you can support the back surface or the arm around the pin properly, but you may have to remove the circlip, only to get enough seating area to support it on the press.
You will need a lot of pressure, 5 to 10 tons probably, but almost every garage has a press that will do that.
They "may" shift with heavy hammer blows, but either way you need a drift just slightly thinner than the shaft, ideally hollow to locate over the threaded stub, so it can go into the end of the arm without jamming, to push it all the way out.
You could try removing the circlip, and pulling it out from the front with a well-oiled hub nut and spacers, but I would not be very optimistic about the chance of success. If you do that, get a new hub nut for reassembly!

sounds like someone was turning a nut the wrong way, a press is the best was as you are not impacting it back onto place.

Yes Mini daves I probably was!! I only found that out afterwards when someone told me that they go in different directions depending on which side you are working on, a hard lesson learnt!!
