Don't worry very simple and straightforward job!

All you need is the car jack and a splitter. no need to raise the car at all, you can do the whole job with it standing on level ground.

1) remove wheel and lower again onto block support under lower control arm (NB! car must be level so that roll bar is not loaded)

2) Loosen ball joint nut until FINGER tight and then split. If nut is tight after splitting jack the opposite side of car up a little and remove nut.(this will unload rollbar)

3)Remove rollbar nut washers and rubber. You may have to pry out the rubber carefully as they often stick to the arm.

3)Jack up the side you are working on untill taper is JUST clear.( I have never found it necessary to disconnect shock)

4)Remove inner bolt and arm can be removed.

5)Clean the bushing bore and pollish a small radius both sides as this can cut the bushings as you press them in. You should be able to press them in by hand when soaped.

6) Reassemble. If taper does not enter fully when you lower the car jack up opposite side until pushed right home. this will hold the joint while you tighten the self-lock nut.
Important! Tighten the bolt only after the wheel has been replaced and lowered onte ground.

Sould take about 30 min/side.
