Little update,
I took the Jeep down to the garage where we then put it up on the ramp to see if we could find out if the box was faulty, when on full lock right the was still a lot of movement in the box and could make it turn more to the right as it was hitting the stops.
So we undone the ball joint that goes on the pit man arm and moved it so it was fully over to the right, we then move the rod arm so it would fit back in the pitman arm and then tried it at full lock left and low and behold it went on full lock left.
We also noticed that all the front track arms/ball joints where new and still had the mopar stickers on so it must have been replaced at some time and not set up right. So now I have full lock from left to right, but now I have an out of line steering wheel. Can the wheel just be removed and lined back up or is it on key way or just a spline?
Cheers
Lee
