alignment

I am having a problem with "hard" driving with my 1998 31ft class c. It is a 450 chassis. I have replaced the steering box and total front end with all new shocks. Front end had alignment but still wants to "wonder" on the interstates . I am thinking the alignment is not right, I read some time ago about the settings of castor R & L with +, more then factory settings. I cannot find the article now. Any suggestions or help/advise?? after driving 5 hours yesterday to my destination campground I was worn out!! short trips on state or county roads not bad.

My 1999 30 ft class C wandered quite a bit on highways, but mostly when being passed by anything bigger then a SUV. I upgraded the rear sway bar to a thicker one and front sway bar bushings to poly and can now drive with one hand.


I was surprised at the difference it made. I have 30,000 miles on it ( 14,000 in the year I have owned it ) and everything else, besides the steering stabilizer is original.


You should be able to find out where the shop set your caster. Many say to go to the max of what Ford recommends. I haven't had mine checked.

Positive castor will make the steering easy and make the steering "center" harder. too much castor will cause a shimmy like a bad shopping cart wheel. Typically 2 degrees over the stock spec would be okay. IE the spec is 3.5 + or - .5 I would hit 5.5 but that is sometimes hard to do depending on how much adjustment you have left. You don't have a ball joint locking up do you?

thanks guys for the input. I have had new balljoints and a total front end rebuild including steering box, all new shocks all around, new brakes, calipers, I had the alignment done same time plus 6 new tires. They were suppose to set the castor + the factory setting. I don't know what the setting was when this was done. I am going to find the specs sheet where the alignment was done but I believe it was set like this...LH +5.3 degrees, RH + 5.5 degrees. I believe this came from something I read on an earlier posting. But this was all done around 2500 miles ago and the tires has no wear on inner or outter edges no feathering. But when a truck passes I can tell it, maybe because before this I had a 34 dt Montana 5"er and a 350 ford dulley and never had a problem in all the years as a full timer. This is my first class C and really hate to drive it because of the wondering, the coach I like, has enough room for wife and I. When I get back to Manchester Tn, I will take it back to the guys that did the work an alignment to see what they say. They should know how to do alignments for they work on all motorhomes, tractor trailers and all cars and trucks. I just know I cannot live with this kind of driving sure is no pleasure "getting" there.

The Ford specification for caster is +1.5 to +6.5 degrees. It appears they ship the cutaways from Ford at about +3.5 Degrees (if for and aft is nose down is 1.0 degree otherwise +4.5 degrees is for and aft 0.0 degrees) which is OK for city driving but will wander at highway speeds. Best results have been obtained with Ingall 594 sleeves where you add +2.0 degrees to both sides to give a final +5.5 to +6.5 degrees.

Twinboat, what size sway bar did you go with? I was checking on sway bars, I haven't measured what diameter mine is but I think there is only 2 sizes for mine and that is a 1 3/8 and a 1 1/2" I believe. And If I may ask where did you get the poly bushings?

I guess the first thing I will do when getting back home is getting the alignment checked even though its been only 3500 miles since it was aligned. There is no tire wear and the tires were put on the same day of alignment new ball joints.

The rear bar is 1 1/2 inch. Got it from Amazon.com. It came with poly bushings.

The front bushings are available thru NAPA auto parts. Not to expensive. My front bar push's into holes in the axle, there are no links.

After doing a several hours of research on internet and with all you guys help and info I believe my problem would be resolved with beefed up sway bars. I am looking at Hellwig front which is 1 3/8" and rear which is 1 1/2". Is Hellwig a good sway bar? it seems like they would be pretty simple to self install. thanks

I just looked up my rear sway bar. It is the Hellwig 1 1/2 inch bar. I installed it last year and about 14,000 miles ago.

I have twisted and bumped this old MH thru lots of bad highways, including NY City highways, country roads, state campgrounds and washed out, dirt, NH mountain roads (Wrong turn).

It was easy to install, with just running the rear tires up on some wood blocks.

I give it a top rating.

I looked underneath the rear of my MH and there is a anti sway bar I would guess from the factory. just by looking it seems pretty stout, when I get back home I will measure to see the size but it seems like could be 1 1/2" . If it is and since this MH is a 1998, would you think that new poly bushings would be of help. I haven't looked under the front, but all bushings in the front down to the tie rod ends have been replaced. Will check all this out when back home next week. Just have to suffer through a 5 hour drive but on the way back I am breaking it up into a 2 1/2 hour drive and stopping over one night at a State park then continue the next 2 1/2 hr on into home. that is how bad I hate the driving. its mostly on the interstate that gives the most problem. State and County rds not too bad but still some swaying.
