Most garages will have a press. My difficult one cost a tenner.
So as a scenario: If I get 2 wishbones of an OOF scraper or fleabay, buy the new bushes and take it all to local garage they'll re-bush the wishbones for a small fee, is that correct?
Well, in theory yes. Trouble is you need drifts that fit the bushes. I had imagined using a larger socket or some similar item. But when the bushes arrived it was clear that would not work for 2 reasons.
1. the outside edge of the bush is 1mill or so wide iirc so the drift has to be a fraction smaller than than the hole in the wishbone but big enough to not slip into the centre of the bush and rip the rubber.
2 the centre "spacer"set into the rubber sits proud of the outside edge obviously so the drift needs needs to have a suitable hole to allow for this or you risk forceing the centre spacer out of the rubber and again, ripping the rubber.
Or something like that, ive not used correct drifts so cant tell you how they fit. But i imagine something could be turned on a lathe to give the right fit. Hth.
For what it's worth, you mite just as well buy some new, ready assembly wishbones and fit them.
It's a lot of extra hastle to remove the old items, sort out getting the new bushes fitted, before taking them back and fitting to the car.
I fitted some pattern parts about a year ago, and they work perfectly fine. Just be carefull with the linkage for the HID light sensor thingy, as the ball joint can be dry and rusty.
You will have to get the steering geometry checked and adjusted afterwards though, if you are to avoid some interesting handling characteristics.
