air system/ride height

[Jack Whitmill]

04 36 ft. Monterey.  The coach has started to drop on drivers side rear, with air at 110 lbs or above, up to 4 inches. This started in the Fall and we had new air bags installed, ride height checked. This seems to be an intermittent problem. When engine is running the 4 inch drop comes up to a 1 inch drop. When level the coach stays level and will hold.
 Any ideas?

Jack,
If you are saying that the coach leaks down on the left side when setting, that is probably just a slow air leak somewhere in the suspension, probably the LR. However, the 1 inch lean when the engine is running is just a rear ride height sensor adjustment, but a 1 inch lean is probably considered within tolerance by most service centers if you are measuring the coach body and not the suspension height.

I just left HWH in Moscow IA. for repairs similar to your description.  Had leaks at all the solenoids with two defective solenoids and a weak level sensor, and a blown fuse for the front travel height circuit.  I got all the O-rings replaced and new coils installed in two solenoids and a new level sensor and a new fuse.  All this with a 4.5 hour labor charge @ $90/hr. for $750 with one day service.  I can't say enough good things about their professionalism and skill.  Also, free dry camping w/ elec. water and dump available.

We spent 2 1/2 days there three years ago having our hyd jack system removed and an air system custom installed. They were superb  with the work they did and also how friendly they were. the shop foreman even gave my son and I the grand tour of the plant and the rv they are building.
