    Default Storage With Air Bags Dumped

    I know this has come up before, but I don't see any downside to dumping the air while the bus sits in the garage. Other than not being able to determine if you have the leans or an aux air leak, what harm does it do?

    Tom, there is no physical harm that will come to the suspension or the air bags themselves if the coach is lowered to its minimum height. I believe that inside the air bag is a rubber snubber or stop upon which the bus sits when the air bag is collapsed. If anyone has an old air bag, maybe they can pull it apart and photo it for us to see.

    The old ones had a top that snapped into place and you could easily open one up. I think the tops now are crimped all around.

    If your bus has indipendent front suspension I would not recomend doing this because it prematurely destroys the upper a arm bushings. I've pulled upper a arms off of chassis with 60k because they were crumbling out the ends in bits and I service other coaches with well over 100000 miles where everything is still perfectly in tact.

    Only difference being weather or not the front end is left at ride height or is dropped down either intentionally or from a leak

    The rear end or a straight axle front end absolutely not an issue dump and lower all u like.

    I think it also has a negative effect on the dog bone bushings also.

    It seems like Joe and Jim may have uncovered why Prevost doesn't want bags dumped.

    For long periods of non use I use stands under the chassis. This not only takes care of bags that may sag over time, but takes the weight off the tires.

    Can the stands be purchased? Interested in taking the weight off my airbags and tires when not in use.

    Wooden blocks work just fine. Raise your coach with the level low, insert wood blocks, and lower the coach. If you want stands, I have a pair similar to these: http://m.northerntool.com/products/s...6_JBoCa0Lw_wcB

    Make sure you use jack points.

    What do you mean raise coach with level low? I know how to dump the air and I know how to raise for travel. That about it as I'm still a newbie.
