That depends if they want to play ball. Can take about an hour a side . Can take a day! My technique as follows:
1: Jack up on subframe.
2: axle stand on manufactures body mount ( the sticky out bit just back from the arch in from the sill)
3: Ball joint nut off. (22mm)
4: with a ball joint splitter (halfords for a fiver) insert and hit ( Hard
May take a while. Just keep hitting it.
5: I remove the droplinks (17mm and allen key)next to give room for the wishbone to slide out. It just makes life easier. If they get stuck angle grinder and order new ones ( this nearly always happens) best just to get some as your bound to need one on 1 side! They are cheap eeven for genuines.
6: undo 4 bolts holding wishbone to subframe (15mm)
7: Pull hub assembly towards you with one hand while pulling wisbone clear with the other. (best to leave keys in car so you can rotate the wheel while you are down there.)
8: push new wishbone into place. (copper hammer or hammer if you havent got one) to coaks it roughly in.
9: get front bush short bolt in first on the wishbone (easiest). Leave it loose
10: connect balljoint to hub and do nut up loosly too.
11: with jack, jack up the hub assembly (on the hub not disc) until the wishbone is horizontal. With a wiggle you should be able to get the short bolt on the back bush in.
12: Using a screwdriver you don't care about and the hammer allign the bushes up with the holes so you can get the 2 long bolts for the wishbone in. If you've not jacked the wishbone level they will never catch the thread and go in.
13: Do it all up.
14: replace droplink.
15 Repeat other side.
16 Go get it tracked. (About £30)
