I was grading my driveway today and the steering stiffened up while turning around. As I turned the steering wheel, it was stiff at first, then loosened up and acted normal. That lasted maybe 30 seconds until I had to adjust steering again. Stiff, then with a heavy turning of steering wheel back to normal. If I constantly move steering wheel a harder left or right, it doesn't stiffen up. Any ideas. Also, just replaced steering cylinder, connecting hoses, 45 connectors, and O-rings a few weeks ago.
