Hi all, I hope I can get a bit of insight from you folks.
I was having a problem with stiff steering on my Newmar Mountainair on a Ford gas chassis. My dealer removed the steering damper and say it seems a little better. I have not driven it yet.
What is the function of the steering damper and if this is not the cure what else do you think it could be? Steering box?
The steering was not uniformally stiff either, while you would turn the wheel it would have stiff spots.
Anyone? Regards.

I think they are stiff by nature judging by my previous Newmar on a Ford.
But if your experiencing "stiff spots" it can be everything from a slipping belt to a bad pump or box...

If I am not mistaken, the steering damper is to keep the stearing wheel from being yanked from one side or the other when you hit bumps, pot holes, or such when moving. Hit a big enough hole and the steering wheel will come out of your hand and swerve hard to one side and might cause a roll-over if it turns hard enough. I would put it back on. I bet the stiffness is more likely coming from a steering knuckle that has refused to take grease for some time and is now frozen with rust inside. If that all checks out, then the power steering pump could be getting ready to fail or is not supplying the right amount of pressure/flow needed to assist.

What year is your coach? Stiff steering seems to be normal on most F53 chassis. If I had a steering damper on my coach I wouldn't remove it unless it's defective.

How does it feel when the fronts are off the ground?

Do you mean when the front jacks take pressure off the front tires?
I cant really answer that question we just got this 1996 coach and have only had it out once.It is still at the dealers waiting for parts on another issue.
If it is still stiff and jerky when there is no pressure on the front end what would this indicate?
Please keep the ideas coming I am learning more everyday!

It is a 1996 Mountainair. I agree with leaving it on, the dealer is taking it off as a form of problem solving to see if it is the problem, they want me to test drive it and see if there is an improvement. Regards, Wade

put the damper back on. It will help keep you going straight in a blow out or ruts in the road. My 99 chassis F53 had very tight steering I believe it is suppose to be that way unless it has just started tighting up on you. I would take it to a Ford dealer not rv.

Make certain the king pins have been properly greased. This means raising the front end of the vehicle to take the pressure off the king pins, to allow grease to properly flow into the bushing. Not good enough to just grease it on the ground.
A dry king pin bushing could cause stiff steering.

Good tip! I know it has been greased but properly I dont know!? I will get it done right to see if it makes a difference.
