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.
