My right front airbag height is an inch lower than the others in travel mode.
(LF = 8 1/2'' ; RF = 7 1/2"; LR = 9"; RR = 9")
I'm not sure that it could cause the coach slightly pull to the right, and would like to take care of it first before heading to the alignment shop.
Please advise.
Thanks,
Michael
Were you on level ground when you measured?
There is no side to side adjustment in front (one ride height valve in front, two in the rear).
Start by confirming that there is no mechanical issue with suspension (unlikely) or plugged air line, leaking dump valve, etc.
Move as much of your movable gear from the RF as you can.
Put left rear 1/8" above spec, right rear 1/8" below spec. And make sure you are using the correct measurement for them-- the measurement depends on your measurement points, and has been well covered. But I am not aware of any 9" dimension.
Michael,
Like Tom implies, it is important to be on (much as possible) perfectly flat, level pavement. If it was me, I would find such a place, and then try a experiment. With engine running (to provide good air supply), first manually raise coach all the way up to max height. Be sure all 4 corners top out. Then allow it to come back down to travel height. Measure ride height at all 4 corners. Then, dump air and lower coach to the mechanical stops. Be sure all 4 corners are bottomed out. Allow coach to return to travel height. Measure ride height again. If you get the same results in both measurements (RF corner low), then I think you can rule out any problem with the HWH system or components. By going to "max up" and "max down" you have exercised all the valves and controls in the leveling system, and they have operated as designed.
The only other thing that could cause one corner low (that I can think of) would be excessive weight imbalance between left and right front corners. Since there is only one height control valve in the front, almost every coach will have a small difference in LF and RF ride height. Usually not as big a difference as you describe. Has your coach always sat like this, or is it a recent development?
Thank you all very much .
Especially Chuck & Jeannie, the exercise does the trick. It seats level on four corners in travel mode now.
Thanks,
Michael.
