New tires almost always feel better because you have more rubber (cushion) between the carcass and the road.

We have a 2004 F53 chassis. Has a 22,000 lb gross weight and a 26000 gcwr. I had trouble keeping it going straight down the road. It wanted to wonder and I had to keep moving the steering wheel back and forth with white knuckles. I had it alienged and they said all the steering components were fine. I started checking myself and found that the input shaft on top of the steering gear box had a 1/4 inch of play either side of center. This was magnified in the steering wheel. I replaced the gear box and now have no problem with the steering. I can drive down the road at 70 mph and no more white knuckles.

How many mile on the MH when you changed the steering box?

My 26,000 GCWR F-53, with 17K, steers fine. How many miles on yours? (Tree'd)

Henderson's in Grants Pass OR has them made for them. They're called "SuperSteer SS100 Bell Crank".

Dunner, my 25,500 GCWR with 55k on handles fine after the modifications I made.

Mr_D, they don't make the SuperSteer bell crank for Ford.

Took our first road trip with the new tire pressures. What a difference! Ride was way smoother and it tracks better. Does not track as good as I would like, but good enough. The amount of tire squat makes me a bit nervous so am glad I kept the pressure on the safer higher side. Will monitor temperatures and if seems OK may lower the pressure another 5 psi.

Happy days.

I told ya...

BINGO! I'll guarantee that is the reason for your rough ride and vague steering.

Glad you got the tire pressures where they belong and your coach drives better. Isn't it amazing what a few PSI will do?
