I changed the oil last week, and when I was going to move it back into the shed, the steering wasn’t working. No issues prior. Power steering pump was replaced last summer. It has fluid in the pump. Seal in the steering cylinder was replaced 300ish hours ago, no current leaks. It will turn right, but not left. If I let go of the wheel, it turns full lock to the right, then I can’t correct it back to middle. My thought is the pump must be working if it’s turning right, and it is circulating when I look in the fill hole. Does this sound like an obstruction in the line supplying the left turn side of the steering cylinder? I was going to pull the line off the cylinder and have a helper turn the wheel to the left to see what happens. I haven’t tried raising the wheels off the ground to see if it can clear any air in the line without load. Any thoughts or suggestions?
