actually for the rack you have to
1. support front of car on jackstands and remove wheels, make sure steering wheel is at 12:00
2. disconnect the rack arms from the wheel hubs
3. disconnect the front sway bar from the hub, and un bolt the rear (front sway bar) mount bolts (to access the rack bolts)
4. disconnect the rack's fluid lines...this may be a bit messy, get a catch pan, also disconnect the rack from the steering column.
5. un bolt the rack from the chassis, and work it out through the passanger side.
6. check the O-rings on the fluid lines, if they look ok then leave, but if theyre scuffied up, or broken- replace. also check your ball joints( cant remember if that is the correct name...its what connects the rack arms to the hub, correct me if im wrong please)
this is a job that could easily take 2 people to do (one under car, other above)
good luck!
