hi all,

my coach drops on the drivers side overnight. i have played with different things and today i used my ultrasonic leak detector but didnt hear anything anywhere.

richard gave me the idea to create a test/isolation setup. it has a pressure gauge and a ball valve. i took off the line on the back of the rear 6 pack manifold and put this setup in between the six pack and the line going to the rear drivers side ping tank for the airbags when.

i measured all 4 corners and noted the air pressure and will check in the morning. last nite it dropped 2 inches on the drivers side overnite.

i have already changed all the rear airbags and checked everything over and over.

here are the pictures of the setup

Is it dropping with the leveling on auto?

Were you able to check the 4 valves for the tag that are mounted to the inside of the frame.

can you determine if it is the drive, tag or both?

dont know.

i have been keeping track of each corner and both front and back drop on the drivers side. rear passenger side stays steady as a rock.

what i dont know is if the rear is so heavy it takes the front down too

when it was up on a lift we checked for leaks and didnt see any. i have replaced all 6 rear bags.

i am trying to eliminate one thing at a time.

tom

Could it be the o-rings on the solenoids leaking?

i replaced them all

I just don't see a leaking rear will drag down the front, unless on a severe angle down toward the front. If level, or close, weight transfers diagonally.
Think we need to wait till AM to read the gauge.

yea. it is puzzling.

tom

yea slides seem to make it worse

Tom,

What kind of Height Control Valves do you have on your coach?
