Question about Ford F-350
Posted by Anonymous on
Hello, You could have loose tie-rod ends or too much play in the steering gearbox. Sometimes in the steering pump you have pressure relief valving which is basically a spring which allows pressure to bypass the main pump body.
For the tie-rod ends, your Mechanic should check them for the front-end Inspection. The steering box is another matter. The proper way to adjust the steering box is to adjust the thrust bolt on top of the gearbox to press down on the internal gears until there is less than 1/2 inch of free-play in the steering wheel. Some Manufacturers want the front wheels off the ground, others want the wheels on the Alignment plates that revolve with the weight of the vehicle on the plates. You loosen the retaining parts on the steering box thrust bolt and tighten it down until the slack is taken out of the steering wheel. Then re-tighten the retaining parts. Allow some slack so the gears are not smashed.
You also have a joint in the steering rod. It can have a fiber coupler or be similar to a U-joint. You would need to hold the steering box side of this joint stationary while turning the steering wheel off center to check for play in the steering column. This connection point could have slack in it.
Finally, front end alignment. Your RV needs alignment like a car. Sometimes you need to go to a Dealer to get equipment supersized for an RV. There are plenty of Box trucks and Tractor trailers that need the same service. You may have to go to a place that is not pretty, but made to keep big working trucks on the road. If Chinook is still in businees, call them for references in your area and ask them for the Specs for your Alighment.
I hope my solutions are very helpful in solving your problem.

You said that you had the front end inspected so I assume that all 4 tie rod ends are good and the front end was aligned. Changing parts without re-alignment can create a wandering condition.If that is the case then your problem could be play in the steering box, which should have some adjustment. You should also check the bushings in your control arms. They are rubber and will deteriorate over time, creating excessive play in the front end. Hope this helps.
