What is the "normal" movement of the steering wheel in a BJ8 before actualization occurs? In other words, how much "slop" in side to side movement is acceptable? I have owned my BJ8 since 1971 or so and over the years it appears to me that the steering has gotten less precise. I have recently replaced the ball joints, etc. All that is left is the steering gearbox. I suspect the steering gearbox is worn and should probably be rebuilt. But, I thought I would ask first as what I have may be perfectly fine.
