Leveling system modules

I'm interested in getting pictures of the HWH units which maintain the leveling on my '96 U-320. I'm still losing air from the front one, both in travel & park modes. It was suggested that I spay 'Jig-A-Loo' into the openings to loosen the check valves but I am not sure where?
