2013 Armada problem with air ride compressor

[freddie mars]

I'm working on this 2013 Armada with 152k mi... yet again. I've been the mechanic of this family car for a while now and quite at a cheap price so I hope we can get this over and done with. The rear is sagging lower than the front. OEM bags were replaced last year with new sensors and compressor, and everything worked till now. I even added Firestone coil spring helper bags (at the request of the owner of course) but one is leaking slightly at the brass fitting. OEM bags look deflated but don't leak. Scanner can manually trigger the compressor, so it's not dead. Could the Firestone bags be the problem? Any thoughts?

Since the compressor is working, that slight leak in the Firestone bags could be affecting the system's overall balance.you can try fixing the fitting or temporarily bypassing the helper bags to see if the OEM system holds up on its own. Good luck!
