New to me 2007 HR Imperial 42PBQ, coach worked great for first two trips, on the way home from storage (for my third) I noticed that the ride height control valve was leaking. Couldn't find exact replacement but one that would work. as i was installing the chassis control link, every time the valve required air the system would squeal. Coach was park in driveway, ignition off, and air system pressurized. Squeal is not coming from RHC valve. As i was leaving in a few hours didn't have time for further testing. Valve worked and keeped the suspension at ride height, but squealed every time valve required air. Will replacing with correct valve cure the problem? Could not find PN on old valve. Do I need to go through the above tests to check all other connect systems? Thanks Leland
