Not sure about your VE (if that's the car you're referring to in your sig), but it was pretty easy on my VT/WH.
You need a pair of external spring compressors and the rest are basic tools.
Jack the car up and place stands under the front frame rails. Remove the wheel/s. Remove the brake caliper and tie it up (never let them hang on their flex-lines). Remove the brake rotor. Disconnect the brake line and ABS cable from the strut's retainer bracket. Undo the 2 bolts that secure the strut to the hub assy. Undo the top retainer plate nut, and allow the strut assy to lower out of the car.
The manual I have suggested to compress the spring/s before removal, but this is not only difficult with obsticals, banging your head and getting a sore back, it's simply not necessary. The spring is still retained by the top plate, so compress the spring/s easily with the strut/s out of the car.
With the spring compressed enough until all the load is off the top plate, undo the top spring retainer plate and swap your bushes.
Assembly is reading this in reverse.
You'll need a torque wrench too.
