Here is a link to FTE Partsguy he is a sponsor. As for the install I can't help you there. Pricey little bugger but nice discount on it.

baker ur truck got a noisy/humming sound? or ur brakes/steering fail completly?
My pump whines like a baby and im slowly narrowing it down to either the gear bo
highly dougt it) and the hydro boost(will replace next weekend)
Ur gonna get a reman unless u buy a new one for like $500....im not trying to take away from FTE partsguy but the best deal i found is at orileys. $150+$50 core...cuz they got 5 stores within 50miles of FT HOOD.
All you gota do to replace is take the two nuts off the master cylinder let it fall forward, take off the 3 rubber lines, two will be fittings. Go inside and unclip the brake pedal from the rod and then the 4 nuts on the firewall then reverse for install.
Since u got the system open...ide go ahead and do a full flush with Mobil 1 SYN...it helped quiet mine down but she still cries.

ill let ya know..ill also do a write up on it...it might be the cure to all these noisey ps pump's some ppl have! 3 days left till the weekend
i got the same problem except when i first start the truck cold(sat overnight) i cant hear it, but as soon as i turn the wheel alittle or touch the brakes it whines. Im just hoping that it hasnt damaged my pump...wouldnt wanna have to replace that again!

well heres the deal i found a thread which someone describes exactly what mine dose and never posted if the brake booster is the fix but here are my symptoms " At idle I can feel and here a grinding/vibration in what appears to be the power steering pump. Turning the steering wheel will make it change tones or go away, and increasing engine RPM's will make it go away as far as I can tell. The PS fluid level is good and I have no leaks. Further, the steering and brakes work fine, but his grinding is very bad" Its not a whinne from the pump its a grinding vibration."
