I have a stock 85 CJ-7 that wanders at high speeds all over the road. In slow speeds the steering wheel wobbles back and forth. And at any speed, the steering wheel is not smooth, but stiff at certain points of rotation. I checked the tie rods, the u-joint, the ball-joints, tires, and even replaced my steering gear box, but no luck. To make it more perplexing, it doesn't happen all the time. Just sometimes. If anyone has any ideas, please help.
