It's a bit of a pain, but doable with simple tools.
Loosen the front lug nuts. Jack up the van and support it on the rails just behind the front tires (not the sub frame as you need to lower that a few inches). Remove the front tires. Disconnect the sway bar link pins, and the sway bar mounting bolts. Disconnect the tie rod ends from the knuckles. Support the rear ends of the sub frame, and remove the bolts mounting it to the van. Once the sub frame bolts are out, lower the rear end of the frame. I did this by using a jack, and placing the jack stands a couple of inches below the frame. Remove the sway bar from the van. You may need to drop the rack a bit more, but be careful as the steering shaft is still connected. You should be able to get at the bolt that attaches the rack stub to the steering rod by pushing up on the boot. Remove the sub shaft bolt. Disconnect the power steering lines from the rack (at the rack). Un-bolt the rack from the sub frame, there are two bolts. The rack should be able to be removed from the drivers side of the van. I replaced the tie rod ends and the sway bar bushings when I replaced mine (new link pins are easy at this time too). The installation is reverse of removal. I measured the tie rod distances when I put the new ends on. The only change I made was that I tied the steering shaft boot down onto the rack so I could install the bolt. I couldn't push the boot up high enough to get the bolt back in. Be sure to install the new power steering line seals that should come with the rack (buy new ones if it doesn't) - the lines are different sizes so you can't mix them up. Torque everything to spec when reinstalling (the cheap Hanes manuals have what you need along with these directions!). It's easiest to install the sway bar brackets when the sub frame is hanging down. Once it's together and running, check the power steering fluid. Get an alignment immediately (I set mine up before I changed the rack).
One last bit of advice, buy the rack with the longer warranty, you don't want to do this twice.

SOURCE: How tough is it to replace the rack & pinion
jack it up put it on jack stands / shake it make sure it's safe . remove tie rod end nuts and split them apart by using a splitter , do both sides .helps if the tires are removed, then unbolt the hoses from either the pump or rack then there's only a couple of bolts and it's out /ready to reverse and put in a new 1. then you may need to bleed the steering system again by turning wheel back and forth to work out air . good luck.

Removing the rack and pinion assembly from a 2002 Pontiac Grand Am Se
To get the old rack and pinion off of the car for replacement involves lowering the sub-frame, removing the stabilizer bar, and pulling the rack out from the driver side of the vehicle.
Important: Get an alignment! Not only is it dangerous to drive with your steering out of align but it will also grate the tread off your tires in a matter of weeks or even days.
