Wandering condition , where to start?
First do you have your corner weights and have your tires at the correct pressure?
Are the front tires in good condition and showing no signs of un-usual wear.?
Has the front suspension and steering linkages been checked?
Alignment done?

My 1990 Superchief wandered quit a bit, especially after I got new tires. They put max pressure at 110 psi. I didn't think i would make it home. Adjusted air pressure and was better. I decided to get an alignment. The shop inspected the entire front end before they would do alignment. I had two control arms that were worn. Everything else was good including bell cranks and bushings. They adjusted replaced control arms, set air pressure, and aligned and it drove great. Now I'll let you know that the previous owner had installed new bell cranks, front and rear sway bars, and safe steer for the front end. Therefore there wasn't much left for me to do.

Hi and welcome to the forum.

Good advice so far. Especially with a vintage rig, make sure you methodically go about troubleshooting the wander problem before just throwing after market parts at it.

I had to add a steering stabilizer to my new 40DP but had everything else checked out by experts first.

Best of Luck

Rick

Assuming all of the other suspension, shocks, ball joints, alignment, tire pressure, etc. is in good shape, if your "Wander", is tail wag (side-to-side rear movement requiring steering correction), the first step is to install a Panhard bar (Track bar). Fine tuning can be done by the various steering stabilizers on the market, and additional or bigger sway bars improve stability. However, none of these other products will correct the tendency of a solid axle leaf spring rear suspension to exhibit tail wag. It's just the nature of the design, especially if the RV has some age.

I had to replace the shocks on mine, they were the Originals on a 10 year old motorhome at the time. They were badly worn replacing them made a big difference in the way it handled. And new steer tires helped also.

If your water tank is in the rear try running with it empty. I know on mine when its full of water it drives totally different than when its empty.

Skip426 I do not have the corner weights, yet. tires are 80 psi all the way around.Tires are in good condition with no unusual wear.I checked the front end control parts and with the exception of a lot of play in the steering box all else checks good.The alignment hasn't been checked but with no front tire wear I didn't think it necessary. I could be wrong, it might be time for a pro to take a gander. Thanks for the input.

Robertandkim Thanks it's my next step.

RickO Thanks

George Schweikle I'll keep this and check on it after I have the frontend checked.

Chaffeekid Mine is 14+ and they look original.

89sandman Water-tank is in the center but thanks for the input.

BA-in-Mich No trailer yet need to get the wandering issue handled first.

Thanks to all this is all valuable advise and I will use it.

It took about 2000 miles for me to understand how they steer...or don't. It's like driving a boat at idle speed; you do a lot of correcting until you start to let it have it's own path.

It'll never be go-kart steering, but learning how it does it's thing makes you less nervous.

JoeG,
The advice so far is good. However when solving any problem one has to start at the beginning and evaluate all parts.
A good truck alignment shop would be in order. There are only two reason a vehicle goes out of alignment. If you hit something and bend a part or if parts are worn. No shop can align a vehicle correctly if parts are worn unless they replace the worn parts. A rig of 1990 vintage may or may not have worn/bent parts because you don't always know what the PO did. You'll need a good truck shop to check that stuff first.
Ask them to show you which parts are worn. They should be able to demonstrate to you the parts and how they're worn. Then they can also tell you how they contribute to any alignment issues.
If you have any sway bars make sure they check and show you the bushings. Sway bars need good bushing to work well.
Once the steering and suspension system is back to good shape evaluate the ride and proceed with other items to correct what you want corrected.
If you are not familiar with things like track rods, sway bars, steer-safe, etc, etc it might be a good idea to do some serious reading on the net and on these forums. There's a lot of good information on older threads covering all these items. If you're still confused PM some of the guys and I'm sure they'll offer some assistance.

Is this a Ford or a Chevy chassis?

Goodyear tires are here:

Michelin also has a website for their tires, etc.
