I am experiencing a bone jarring tooth rattling ride on a 1999 F53 Ford chassis motorhome. The shocks were replaced in '08 with a recognized manufacturers brand. The vehicle steering is not precise; it doesn't wander but requires constant attention.
Can anyone offer suggestions/recommendations on cause of hard ride and steering and a solution.

 

I fixed the wandering steering on my 1997 straight axle F53 Ford front end. Installed and additional 3 degrees of caster with shims. Now she steers perfectly. I can travel at any speed and thread a needle with that motorhome. The steering is now what you expect steering to be. I no longer have to "think" about driving. I don't have to "herd" it down the road through constant "adjustments" to the steering wheel. I hope this helps...
