Notes of interest for wishbone replacement:
1) Get a ball joint splitter the right size. I borrowed one from a friend (a screw type, but not one of the scissor ones) and only found out it didn't fit half way through the job. Had to put everything back together and go to the shop for a different one. I ended up using a big 'hit it with a hammer' type which worked well, though it needs some hard hits to work
2) Remove the droplink from the anti roll bar before you undo the other bolt at the bottom. If you put a jack under the bottom wishbone and raise the suspension a bit you can release the tension on the roll bar link. You can't do this easily once you take out the big long bolt at the bottom as this disconnects the bottom wishbone from the shocker. I did it the other way round (as all the instructions tell you) and it made it a real pain getting the drop link off as it has a lot of tension in it then. Didn't make the mistake on the second side though. Let the suspension back down before you take out the cross bolt.
3) I was worried about taking the big cross bolt out at the bottom in case the spring and shocker were still compressed. Don't worry, they're not. Just take the bolt out.
4) The thing on top of the suspension turret inside the engine bay on the drivers side doesn't seem to be an engine mount. At least, if it is then my engine didn't fall out when I undid the bolts on it!
I think that's about it. Other than that you can just follow the instructions in the above post. Oh yeah, one last thing....
5) Make sure you slacken the nut on the long bolt that runs through the upper wishbone before you undo the nuts at the top of the suspension turret. I did this on the first side and it came apart fine. The second side however I followed the instructions more closely and left it until I'd taken it out to slacken. By this point you've got nothing holding the parts, and I ended up trying to stand on the thing while undoing a seized nut with a spanner on the bolt end too. Must have looked ridiculous to anyone else out in the street
