its not the worst job to do. i wont lie, it kinda sucks if its your first time. theres a few good how tos out there. the only part i skipped in most of the how to's was not to remove the master cylinder to get to the power steering pump lines, they can be reached just fine from underneath the car.
all the write ups say its a 2 man job, i did mine solo, the only help i had was a friend to wiggle the steering wheel to get the steering shaft back on the new rack.
took 4 hours, from start to finish, like tools cleaned and put away done. so maybe 3 hrs of real work, a few breaks and such.
i also backed my car up on ramps, then jacked the front up and used jack stands under the front, this adds a bunch of room under the car.
