HWH Active Air issue - left front cycling up and down while air leveled

[J&JD]

Maybe you got the defective front air bag that I sent back to Freightliner. It would have looked brand new. When I had my initial problem with the right front airing down I spent hours and paid for hours of checking for leaks all over the coach with both leak check solution and sniffers that detected leaks. A few small leaks were found but nothing that would allow such a quick drop of the right front. Finally I had the front bags changed even though there was no indication whatsoever of an air bag leak. As soon as I started driving the coach the new left front bag started leaking so badly that when I stopped I could literally watch the left front cycle up/down within a few seconds. Called Freightliner and they sent me a replacement and all has been perfect since with the spending of many $ for the bags and replacement labor. So the moral of this story is you can have an undectable airbag leak hiding behind the mountings.
