I have an 88 Comanche, 2 wheel drive. When going down a straight road I have to continuously keep moving the steering wheel to keep going straight. All of the linkage, track bar, tie rod ends, steering damper seem to be tight. I checked the ball joints with a bar under the tires and there is no movement. The wheel bearings were loose and I replaced them. If I lift the front end of off the ground I can move the steering wheel about 1" before the wheels start to move. Is this ok? The tires are all worn evenly. The control arm bushings have been replaced. Does anyone have any suggestions of what else to check.
