I have a 90 Prevost and am wandering all over the road. Had it aligned 3 times by 3 different places. Ft worth Prevost, Jacksonville Prevost, and Brass in Williamsport Pa. Had one tie rod end and the main cross menber replaced.
As I go down the road I have to make very small adjustments both left and right. Very Fatigueing. Talked to 85 Prevost owner and he had same problem and solved it with Steer-Safe. Before I do it I would like to hear from someone who might have another idea. |

The steering wheel on my 82 Prevost moves with the suspension. You cannot lean on the wheel and hold it in position. If you do the bus will steer back an forth on bumps in the road. I learned to position my hands lightly on the wheel to allow it to make its natual movements and I adjust only for tracking.
Yes toe in could also be the problem, but try letting the steering wheel move its own pattern with the bumps. After you get used to it it is no problem. |

You also may have to much air in the front tires. Have you weighed the front axle and adjusted air pressure to the correct specs.
My experience with radial tires is that overinflation makes them feel like I am driving on Ice. |

I agree with Stephen i also have an 82 Prevost, and i noticed the less pressure i used on the wheel the better it responded and less corrections needed, i think as i drove it more and became accustomed to the steering i eased up on the sterring wheel, and it seemed much better. |

Have you had the REAR wheels alined??? They can cause just the problem you have! The rear end starts tracking to one side and you have to saw at the front wheels to hold it on the road. |

There are a lot of things that will cause the problem, but i dont think any steering device is going to fix it, my 06 did the wandering thing for yrs , had it aligned rebuilt the entire front end replaced all the radius bushings, still did the same thing, got to doing some self checking and found the toe in toed out so all that money i paid that shop was for them to make it all worse, dont assume anything, after setting the toe in she steers great. i would look at the toe in first, and the caster, all things conected to the front end , radius bushings front and rear, something is worn out. i always heard that the prevost steers good when right. it wasnt designed for any steering device and shouldnt need one

Lew - just a thought - something I need to do also - how are your shocks? - I'm gonna replace mine and see if that removes what I call the "Caddy" sway - Niles |

Am I reading this post correctly?
"I have to make very small adjustments both left and right"
I don't know of any vehicle that does not require minute steering wheel movement even on straight roads!! |

I'd like to reinforce Jim H's comment. I'd forgotten about that point on first reading of this thread. It's been mentioned many times in the past 9 years and reinforced by several confirmations.
There's such a long wheelbase with a bus that mis-alignments that would be insignificant in a car can become so in a bus.
Minor accellerations, slowing, light braking can be enough to shift the location of a rear axle if the bushings are worn enough. |
