Anyone DIYed teh Power Steering Pump?

[aTOMic]

*THE power steering pump, sorry.

Well I'm at 105k miles on my 2004's 4.2L BFM (petrol) engine and the PS pump has given up. The PSF is foamy, the pump sounds like an old mechanical siren, and the pulley has visible runout. I've found the service procedure and it says to put the bumper into service position, but I'd like to avoid that if possible. So:

1) Has anyone here done this job? And if so,

2) Is it doable with the car's face intact?

TIA for any input,
Tom
