What are the symptoms of steering box going out
My wandering and intermittent power steering loss issue is back with a vengeance. I was getting on the highway yesterday, and felt as though I had no control of the front wheels. I pulled over and checked everything and all is still tight. The feel I'm getting in the steering wheel is like the wheels are being pushed back and forth left to right. I felt the PS problem first, and then the wandering started. I had PS'ing, but I had to use more effort to make it turn and then it was all over the place. I got back in and had no issues the rest of the day.
My question is, what am I going to feel if the PS box, (not the pump), is going bad? Is there a valve in the box that could be going bad, not opening or not closing that would move the wheels?
-I've done nothing to the front suspension or steering. Tie rods are probably original, but tight, and the wheel bearings are nice and tight with no play, and the steering box isn't loose.
