MUD does the steering pump affect the braking? Honestly didn't know that.
How?

I bet you have a broken wheel sensor on one side of your rear axle... Those damn things are glued in there. They break real easy when you swap gears.

Yea...the H2s have hydroboost- that powers your steering and brakes. May god be with you if you ever blow your steering pump and have to make an emergency stop. I think a freight train could stop sooner.

I snapped the shaft on my pump clean in half raising hell in the snow one night. It is very easy to do...all it takes is full crank on the steering wheel and jabbing on the brakes hard at the same time...wasn't more than 1 or 2 seconds of high resistance against my wheels and applying the brakes.

My new AGR pump was built w/ chromemoly shaft, so i'll never snap that damn thing again.

Thanks thats good to know. This is the first truck i've ever owned and had never heard of hydro boost.

Do you know if there is an easy way to test the steering pump to see if it needs to be replaced? I've had a couple OH **** moments when i stabbed the brakes and didn't think i would stop. Wondering if that might be my problem.

Every H2 and GM truck brand new had/have **** powersteering pumps. If you have any steering wheel resistance in parking lot manuevers (no throttle, hard turns of the wheel to get in/out of parking spot/space) GM wont do **** about it. If you want to fit it yourself, call AGR and have them build you a pump. It makes driving so much more pleasant. I can throw my steering wheel and easily turn my 37" toyos on hot pavement. It gave my back, atleast feels like I got about 20% boost in braking power. My bad ass pump - chromoly shaft, needle bearings and every other upgrade there is ran under $400. I still say I wish that was the 1st mod I did on my truck.

you should try to find the paper work on the one you bought so we know what model to look for and extras.

AGR website is junk really. i have been to it many times, and it doesnt really make it easy to build a pump with the options you want.

Its the same pump that comes in their rock ram kit...I think its sold individually as their "super pump". But I dont believe the options I got are on any websites...just their base kits. They can do anything you want to it. Chromoly shaft, upgraded needle bearings, swear there was one other thing they upgraded. I'd get the pump w/ the tank already on it. I swapped mine out, little bit of a pain. Just call them up, good guys to talk to.

My shop talked to AGR about all this stuff today. I'm going with the Rock-Ram kit, which includes the other upgrades. I'll post here what we end up getting with the kit.
