Re: wishbone nighmare
Just to add my experiences - I've just done mine (156) - took a whole day to do both sides. Removing the wheel arch liner helped as it allowed more sideways movement to get the old arms out and the new ones in. I (eventually, after lots of trial and error and swearing) got the wishbone mountings roughly in place then gently lifted the hub with a scissors jack, which allowed the ball-end of the arm to be lifted higher, which then allowed me to finely adjust the position of the arm until all the bolts went in easily - if they are difficult to screw in then you are not lined up properly. I screwed them in so that the ends of the bolts just protruded from the blocks - that way all the thread was being used for strength, but there was still some leeway to move the arm about. On both sides of the car I found that I had to use a long welding clamp to clamp the in-board end of the front mounting block (the long screw one) to the sub frame otherwise the screw just would not reach it.
After getting the mounting screws in I then lowered the scissors jack and levered / forced /manhandled the hub carrier down and the wishbone up enough that the threaded end of the ball joint was resting on the hub carrier near to its hole - then !!gently!! persuaded it with a hammer and screwdriver to mate with the hole - in hindsight that was not clever as I nearly wrecked the thread; next time I would use a soft wood dowel or a rubber ended thing - but it worked.
I didn't remove the drop links, which may have made things more difficult for myself, but their nuts were seized solid and the allen sockets worn smooth and I didn't have any replacements, so grinding off wasn't an option.
On one side I did have to grind off the long bolt that goes through the ball-end bush 'cos it was seized solid - and I am still waiting for a replacement! - so I guess my main tip is, well in advance of actually doing the job, to liberally wd40 everything then one by one loosen off (and re-tighten!) everything that you are going to have to remove - then if something is seized at least you will have time to order replacements before it's too late!
