I have never done one on my own before today, but all it took me was 1.5 hours to do 1 side from start to finish (outside in the rain).
Im no whizkid mechanic but in all honesty with a bit of common knowledge found it quite easy.
Using a 16mm socket remove bottom bolt and stabiliser bar
Using same socket remove the 3 bolts holding on the plate around the bush
Unclip the handbrake cable and ABS sensor wires form their holders
Pull the beam away from the chassis and insert tool over bush
Using a 24mm spanner and a 24mm socket wind out the old bush
Keep going until it is fully out
Ensure new bush is correct by comparing to old one
Reverse the tool to re fit the new bush in place
Keep going until all the way home
Slide the beam back under - re fit bracket with 16mm socket
Re fit long bolt through centre of bush and stabilising bar
Clip up the handbrake cable and ABS sensor wire.
Stand back and take pictures for the forum lol.
