Just to add a comment on lower arms. Having followed the popular link on here to the guide by the guy from Germany or Holland? I can definately recommend removing the driveshaft first as it's a right p.i.t.a. to do otherwise. Only six capheads holding the shaft with nuts held captive by the casting on the back so you only have to fiddle getting the thread to catch from behind before doing them up tight again.
Having removed the shaft and set it carefully to one side, you can then take off the suspension leg, making the job lining up the wishbone much easier with more room for manouver.
I saw another post that said someone couldn't line up the furthest away bolt at the rear (into the soft alloy cast threads) and this stumped me also. I admit that I'd opted for one of the cheaper fleabay sets and, after much headscratching, it appeared that the casting was slightly more square than the one I'd taken off. So a bit of filing to make the edge more rounded seemed to allow it to position better into the recess in the chassis and from there it was easier to align the bolts.
Another tip on removing the bottom ball joint - As there is the disk shield preventing you from hammering a ball-joint fork in far enough to split it, I used the scissor-type splitter as sold by Halfrauds. Not the cheapest but did the job with little drama.
You're still left with a bit of wrestling getting everything back together, but definately worth undoing the driveshaft, as others have commented on.
