    I recently put in the AGR steering box for crossover steering. As I had other stuff going on also, I just took the truck out for a test drive this morning. It makes a really strange whiny/grindy noise and it is very stiff, almost like it does not have enough fluid pumping through it. Anyone else have this problem with a steering box swap?

    How do I get all the air out? I thought I was just supposed to cycle the steering several times and add fluid as needed. Is that right? Do I just need to keep driving and adding fluid until it feels right? Is there anything I can adjust?

    Besides being stiff and noisy it works great. No bump steer, no slop and very responsive (to a strong input), meaning the tires turn further with less steering wheel turn. I don't even mind the slightly stiff steering, although it should be easier, I just want to get rid of the noise.

    Jack the front wheels off the ground to bleed it. Add fluid, turn back and forth, add more, and keep doing that until its full.

    I bought an AGR box last year and unlike many others thank GOD, i've had no problems. Except when pulling away from a stop while making a tight turn , there's a slight whine from what i think is the new AGR pump but could be the box. doesn't seem like its hurting anything, is this the problem sound your having?

    Thanks. That fixed it. I cycled the steering many many times. Turned it off and filled the pump and let it sit while the bubbles disappeared and repeated several times.
