Steering problem

We have a 2007 Fleetwood 36D and it has been difficult to keep the coach going in a straight line.....It wanders quit a bit, seems like there is too much play in the steering wheel.
I have installed sway bars, front and rear. Installed a steering stabilizer. Had the front end checked for alignment. very slight adjustment to camber. I was also told the steering box could not be tightened to avoid some of the play.
I am now wondering if I need to replace the whole steering mechanism??? the coach only has 18,000 miles
Anyone please help out with a move in the right direction.

Your RV has a WorkHorse chassis. What brand steering stabilizer do you have?? Safe T Plus http://www.safe-t-plus.com/ steering stabilizer corrected all my steering conditions.
Not much milage on your coach to consider a bad steering bell crank http://www.hendersonslineup.com/prod...parts/steering

Which chassis is it built on?

I would start with checking the tire pressure. If your tire pressure is too high you will have problems with it wandering and a rougher ride.

Good Luck,
Jon

You didn't mention a track bar for the rear end. Got one on the coach? Like posted earlier, proper tire PSI, for the weight being carried, helps tracking quite a bit.

That is correct, it is a Workhorse chassis. I installed a Roadmaster steering stabilizer. Tire pressure is always around 100psi.
I also was told it had backend sway because of the shorter wheel base, Would additional Springs Help ?

I believe it does have a track bar in the rear. Not positive. will have to check on that. I thought the Roadmaster sway bar would take care of any sway in the rear.

Track bar and sway bar handle rear end movement totally differently. 100 PSI may not be correct (too much) for the weight being carried. Try to get the coach (loaded for travel) weighted. Then adjust PSI accordingly.

The Manual suggested 110 for the front..... 100psi for the rear, so I went under that already, (100psi) but I could lower the psi by another 10psi on the front to see if that does anything.

Hi,
First of all when diagnosing a handling problem as well as a lot of vehicle issues you need to start at the beginning and check all components before you jump to conclusions and start throwing $$$$ at a problem. All components of the steering and suspension system can be checked for serviceability. Are your springs still arched or are they flat or ?? Do you have any cracked springs?? The alignment angle that really effects tracking is caster. A chopper motor cycle has excessive positive caster with the wheel way out in front of the weight. They will track straight but not turn very easily. A good alignment shop could add a degree more of positive caster and that will increase tracking. That also makes the steering a little harder but with power steering it should not hurt. Check the tires: Check pressures. Set it at the high and low end of the recommended pressure range to determine if it has any effect on your issue. If not then set it at a comfortable setting so the ride is not to harsh. Now check all anti-sway bar bushings and the bar link connections to the frame and the bars. The anti-sway bar won't work if the bushing are worn. If the bushing are suspect have new blue poly ones installed. You can get them on EBay for about $50 a set. If the shocks are old or not a good factory shock get new ones. Bilstein or Koni are good. All steering components can be checked: tie rods, idler arm and king pins. Your chassis is not that old to be having any issues with those parts but one never knows.
Checks these items before you start throwing $$$ at the problem. If all this stuff checks out then maybe start improving hangling components like anti-sway bars, or trac bars.

Hi daveandviv,
The brand of tire needs to be known. If it is Michelin, consider:

Go to the Michelin site and determine the PSI that should be in the tires. Go to Michelin Americas Truck Tire Load & Inflation Tables

Dave,
Our Tiffin Allegro Open Road 35 TSA is on the Workhorse W22 Chassis. It has Goodyear 19.5 tires on it and I keep the front tires at 95 PSI. The rear I keep at 85 PSI. I have hd no problems with it wandering even before I installed a Safety Plus steering for safety reasons.

Good Luck,
Jon

If you will look in the site FILES section, you will find an article I wrote a few years ago on Motorhome Handling Problems and Solutions. It will explain what causes various problems and the actions used to resolve them. By the way, one of the common problems is the driver over-correcting on the steering and that, a well as mechanical fixes, are discussed. However, a steering stabilizer is not one of the recommended fixes for the problem you described.

100 psi sounds a little high for the size tire used on most Workhorse chassis, but we need the specifics for yours - tire size, chassis model (e.g. W22) and weight (if available) or GVWR. Excess tire pressure will result in what seems like loose steering.

This is an excellent article. Answered all my questions and points me in the right direction, since I am experiencing the same problems. Everyone having handling problems should read this article. Thanks.
