replace the power steering pump

Have a 2000 Express van. Steering is making a crazy racket. Sounds like it's coming from pump. Have been looking for an answer in here about how hard this is to replace. Also could use some tips on making it easier.
Thanks

i'm just trying to bump this thread. i want to know how hard is it to replace the steering pump. they must never go bad on these vans. except for mine and yours.

I've done them om M-vans- probably need the power steering pulley puller tool. To get the pulley out of the way.
