Safety steer

Our 04 W22 was situated with probably the heaviest gas coach built being a Newmar Mountain Aire. Never had one problem with it going down the road and it was bone stock. I think a lot of these modification needs are in ones head. Air the tires up correctly and you should be good to go. JMHO

Doug,
What you suspect is Sumo spring is actually the stock factory bumpers that come with a Workhorse "W" chassis. They come in different colors depending on the axle weight. IN addition to your front end alignment as recommended, you may want to consider a thrust angle alignment that insures that your rear axle is in perfect alignment with the front axle. I am sure that you have seen vehicles going down the road looking like they are "crabbing". A front end only alignment will not correct this. The problem is that most truck alignment shops cannot do this so you will have to search for one that has the proper equipment.

Thanks Grace. Will follow your advice and see how it works.

At 60k miles I would replace the shocks and get an alignment and getting the caster right. Do the yellow bumpers touch the springs or is there a gap between them? A good alignment shop can check your ride height as well as sagging or worn springs and other components for wear.

Sorry, mileage on shocks/springs are at 59,000 miles.

Rv mileage is currently at 59,000 miles.

I have bilstein shocks, original from factory in 2005. Also have what I believe to be sumo springs. They are rubber covered springs, yellow colored and mounted below the front shocks. Both could be bad or still good. Not knowing, should I replace both.?

Your weights look pretty good. If you add the weight of two average middle age passengers, say 200 lbs for you and 150 for your wife that brings the front end weight up to 7360/2= 3680 lbs for each tire. 14,500/4= 3625 lbs for each tire. I think your weight distribution looks very good so I do not see the front end being light or the cause of bad handling. As I said in my previous post I would get a good alignment and focus on getting the castor right. How many miles on your MH/shocks? Do they need replacement? I think a good alignment shop can tell if anything is worn, broken such as shock mounts or need replacement. Other things to check for is unusual tire wear, balance, out of roundness. These would also cause vibration in the steering wheel or seat. Good Luck.

Yes, weights were as follows:

Front axle weight. 7010 lbs

Rear axle weight. 14,500 lbs

Very close to previous weigh ins.

Did you get your exact weights yet?
