When you disconnect the hydraulic lines from the rear air leveling shock or from any of the 4 shock/struts, hydraulic fluid will leak out and introduce air into the HBMC lines.

Thank you I tried to do it today and I got everything off but the top bolt I can’t find a socket the right length so I tried a box wrench but I can’t get enough on it so I think I’m gonna be stuck taking it to the dealer and they can bleed the system also

Spray some PB blaster or Sea Foam deep creep to help break down any rust, corrosion, etc.
Even applying a little heat from a propane/map-pro torch will do the trick.
