Got down to the coach yesterday. I drove it onto leveling blocks just to get a couple more inches and set some chocks on the front wheels, then jacked up the passenger side and set wood blocks under the pivot point of the suspension. I found that the ride height leveling valve had a crack near the linkage attachment.
           

Not sure why it broke but it could be that the grommet degraded and allowed the linkage arm to come out of alignment but that is just a guess. I made a new grommet for the other side when we first got the coach (some of you guys from years ago may remember the air ride was out when we bought it), I check on the repair and it still looks great. I used some heavy fuel line over the metal spacer used for the original bushing and a couple of washers to keep it where it belongs. Here is what the passenger side looks like when the valve and linkage are installed:
   

Luckily for me I purchased a spare when we bought the coach, Newell stated that it would need some adapting since the original was not available (I remembered this after asking after finding my notes from previous repairs). The replacement valve is Prima Brake Components part number LV90054007 and will need some modification to the linkage arm to allow clearance for the pivot. I am thinking of straightening it and then drilling a new hole for the linkage attachment.
