1 1/2 hours! No chance - even with a ramp. Take you time and reckon on best part of 10 hours if you use a jack and do all 4. Bet your bottom dollar you come against a stiff nut etc. Spring compressors cost me a tenner from motor factors. Replace all top mounts and bottom bushes. The bottom bushes usually come with the strut. Personally I just cleaned up the springs and replaced the struts with Bose gas shocks - £27 each.
Flats on the strut thread at the top end meant I did not require a special tool for the rear, but the front is a different matter. Again motor factor should supply. Hayes manual shows how to make one yourself - not difficult.
Agreed that camber and tracking to be checked afterwards, but drive it a while first to let it bed in.
