Not too bad. Done this job myself.
Firstly, Haynes states you have to release the hub nut so to remove the drive shaft. You don't need to do that.
Wheel off etc. Also remove the undertray. Use a ring spanner to get the ball joint nut moving then use an open ended spanner until the nyloc section has freed from the top of the thread. Then put a bit of gash timber across the wishbone and thump it down with a hammer to release the ball joint from the strut, however do not do this until that Nyloc is free. Remove the ball joint nut and allow the wish bone / strut to separate. The rear bush mount is then to be released from the subframe by removing the two bolts. There is a location pin which causes resistance when it separates. The front bush is simply a case of undoing the bolt passing through the bush. (Now you will see why the under tray has to come out first). With the old wish bone now removed you can swap the bushes over to the new one as necessary. Refit the bushes to the sub frame and torque up. Locate the ball joint flange in to the strut. Fit the new nut and do it up to the point the Nyloc starts to resist. Now use the hydralic jack, placed under the wish bone to gentle push the flange into the strut. This will stop the flange rotating so you can start doing up the nut. You obviously can't torque the nut so do it up as tight as you can with the spanner. Its a Nyloc, it an't coming undone. Put the other bits back and the jobs a good'un.
Hope this helps.
