I watched the video link set. I found the leak on one of the drive axle brake relays. A 3/4" plug had been installed without thread sealant.
Drivers back (left) bags never fully inflate or deflate. This set of bags is receiving air from an unknown source. The kip solenoids have brand new plungers/seat, o rings and springs. The closest drawing I could find on hwh's website is mp75.2108 23sep04. For the drive axle manifold it seems to show the raise valves supplied in parallel with compressor air. The enclosed pic seems to show right side supplied with compressor air and the left side from another source. The travel solenoids are supplied by the HCV's. I can't access cad drawings of the manifold. I have emailed HWH, they indicate a wait time of 4 weeks.
Thank You Brion
