2000 Marquis leans
« on: December 02, 2019, 06:17:16 PM »
Have a 2000 Marquis that rides level. Right side will lean after a few days setting. Checked for leaks with soapy water and spray bottle and found no leaks. Suggestions? Air bags cracked but seem serviceable.

My '99 Marquis tends to do the same.  If I know I am going to be parked for more than 48 hours I dump the airbags and all is well.  Other post on this forum indicate that leaning to the drivers side is a common issue with our era coaches.  I have the HWH air/hydraulic leveling system and if I leave it on while parked it maintains ride height level.

For leaks I would check the air leveling valves first, then the push on connectors, both these can have minor leaks.  When mine was leaking more than it is now I could just hit the air dump and level the coach.  Mine was the rear leveling valve on the drivers side.  It still worked and I could not see it leaking by spraying it with soapy water, but once I replaced it it held air and the needle remained steady for days.  I kept the old one for an emergency spare.

   Hey Mitch, leveling side to side is controlled by the rear height control valves, your issue is on the drivers side rear. When I Park, I always dump the air at the HWH control pad. That way my sweetie can walk right in. Fred

It is not unusual to have the HWH air leveling manifold(s) leak (a.k.a. "6-pack valve").

I found my HWH valves for the drive axle and the Tag axle leaking. There are three o-rings for each solenoid, so plenty of places for leaks. I sprayed  soapy water (I bought soap specifically made for finding Air Leaks) on all the valves and fittings. This leak detector soap leaves suds on the fittings longer and will show leaks/bubbles several hours later. Regular dish soap and water mix is usually not enough to find these small leaks).

This is a link to a page showing how the valves are assembled and gives the 0-ring part numbers/sizes. http://beamalarm.com/Documents/hwh/hwh-solenoid-valve-disassemble.html

I want to thank everyone for the advice.   Air out when we arrive as long as it leveled when driving.
