WH Chassis ride height

Does anyone know what the ride height should be on a WH W 22 chassis? The distance from the rubber bumper in front to the frame. I looked at one this morning and the rubber bumper was resting on the frame.
  • Certainly that does not sound like normal tire wear. There is not much that is adjustable on the front of the WH chassis so if it is sitting that low it could affect the tire wear as well as give a very rough jolt if you hit a bump. As I said, if the coach is unloaded, imagine what it would look like when loaded for travel. I'm sure there is a serious spring problem which is not that difficult or expensive to fix. If you really like the coach, I would guess that you could get the springs fixed or replaced for $1500-$2000. Now if you could negotiate a $5000 discount....well.

    If this coach is sitting on the bumper now, and it is UNLOADED, then there is a spring problem.
    Thanks Ron that is what i was looking for. I also noticed the out side if the tire warn like a long scallop not short and wavy. Would you think the ride height or lack of it would cause that condition?

  • I would look for a broken leaf in the spring. That would be an easy repair for a spring shop. I have the complete set of W22 service manuals downstairs in one file drawer and now I don't own the Newmar anymore.

    "Gjac"....whenever you ask for help or opinions, it would be nice to know what coach you're talking about. In your profile, you show a 1996 P30 chassis on a Georgie Boy. What coach are you talking about here and how old is it.

    I know the "P" chassis' had airbags on the font and took some testing to get them to correct height and a good ride. Mine was 65psi. I don't know the "W" chassis that well, but I don't believe they have air bags on the front.

    How does the front of your coach sit, low, level, etc. My guess would be that you have some tired front springs. You're right, sitting on the bump stops is not good. Maybe some of the older "W" chassis' came with air bags.....hopefully someone jumps in regarding that.
    The question my in my op was for a WH W22 chassis. Its a 2005 Admiral that I am looking to buy, I have an older P30 and am not familiar with the WH chassis. I just don't believe it should rest on the frame with not spring travel.
  • Mine has a couple inches gap. You may have weakened springs. May need another added or replace the ones you have.

    . It just doesn't look right to me with the bumper stops resting on the frame. I would think the the springs need some gap in order to work properly.
