First thing is to slacken the driver’s side wheel nuts before jacking the car and securing on axle stands.
After removing the wheel remove the brake calliper to create a bit more space to work in, and any plastic trim/splash guard that is in the way. Make sure the brake line isn’t stressed by fixing the calliper to the chassis (or wherever) with string.
On your back under the car, remove the bracket that bolts through the bush.
Remove a blade from a small hacksaw and thread it through the bush.
Replace the blade upside down in the saw and begin to cut through the bush outer metal case.
Once you have cut through, lightly tap a suitable screw driver under the metal case and fold the bush in on itself.
