Ok, 235 75's are totally fine. I was just curious if you were running wide/low profile tires on the front like I am. They actually make the problem worse as the wider tires track with the road more.
There is an adjustment procedure for the steering box, and it's very simple. I did it to mine originally, and it felt a little better, briefly, but then got loose again. I installed two new reman boxes before finally buying a RedHead box. I actually wanted the BlueTop box, but every time they had a sale on, they had no stock on the Ford boxes, and RedHead did, so that is all that drove my decision. I might try a BlueTop in the future.
They do make a noticeable difference.
The Ford trucks I’ve had have been long wheelbases. My 86 drives nice. But I may just be driving like 66gtk said, know your vehicle.
But my Bronco is a different story. If I haven’t driven it for awhile it gets my attention. I always considered it aptly named. Very short wheelbase.
I think Ella did a great job. On teaching my three kids to drive the youngest scared me! Until we bought her a smaller vehicle. She was getting the hang of the Bronco though.
