kentelarsen Report post Posted November 20, 2015 I have a 2006 National Tradewinds on a Freightliner Chassis and occasionally have problems with the left front suspension bag inflating. Has happened twice in the last few months. The first time it eventually sealed and inflated. The last time did not. Any help out there? Thanks. Share this post Link to post Share on other sites
wolfe10 Report post Posted November 20, 2015 Was the leak at the bag, or in plumbing to it? It is a little odd (assuming you have a straight axle, not IFS) since you only have a single ride height valve in front which supplies both front air bags. Share this post Link to post Share on other sites
kentelarsen Report post Posted November 20, 2015 It leaks at the point where the air bag would normally seal against the bottom-side metal "rim". If I deflate the system and raise the jacks fully on the front, the entire "rim" is exposed so I was able to clean that. When I lower the jack and fill the bag it won't seal tight against a portion of the "rim" and leaks there. One time it happened it eventually seated and filled and wasn't a problem until weeks later. Odd indeed. Share this post Link to post Share on other sites

desertdeals69 Report post Posted November 21, 2015 It sounds like the bag is ruptured. It does not seal against the cone. Share this post Link to post Share on other sites
