bigredhdt Posted July 25, 2016 Report Share Posted July 25, 2016 My rear leveling valve went bad, fully inflated bags. I only noticed it by the growling noise from my driveshaft. That noise is unnerving to say the least. If I use the dump valve my bags air back up when I shut off the truck. I have disconnected level arm and leveler is not responsive. I would cut a line to an air bag, but I would have to bring under the truck when I do that. (Scary) Anybody have a good idea? Ps. Anyone think I should change out bags since they were technically overinflated? Link to comment Share on other sites More sharing options...
Darryl&Rita Posted July 25, 2016 Report Share Posted July 25, 2016 Dump the air tanks.

bigredhdt Posted July 25, 2016 Author Report Share Posted July 25, 2016 Tanks are empty. Rear air bags are full. Link to comment Share on other sites More sharing options...
Darryl&Rita Posted July 25, 2016 Report Share Posted July 25, 2016 Then crack a fitting and let them bleed down. Or use the bag dump switch to dump them. Once they're dumped, assuming the tanks are empty, they can't re-inflate.

sclord2002 Posted July 25, 2016 Report Share Posted July 25, 2016 Run truck to build up air, shut down engine, turn starter switch to ON, use dump switch to dump rear bags, dump air tanks with lanyards, turn off ignition switch and bags will stay deflated. I do this when overnighting sometimes to level the camper from nose to tail. Be safe, Charlie Don't ever tell a soldier that he doesn't understand the cost of war.

Darryl&Rita Posted July 25, 2016 Report Share Posted July 25, 2016 Why build air to dump it?

Big5er Posted July 25, 2016 Report Share Posted July 25, 2016 I'm with Darryl, why build it up??...but I'm with everything else that Charlie said. With the key on, dump the suspension, drain the tanks and turn the key off. Can't re-inflate if there is no air to use. EDIT: If you have a low bed on your truck (like I do) drive the rear end up an a few 2x10's to get a little height to help with crawling under after you dump the suspension. Make sure to chock the front wheels too.

Asross72 Posted July 25, 2016 Report Share Posted July 25, 2016 Why build air to dump it? I believe I read somewhere that the air accessory switches won't work until the main system reaches a certain PSI. So need to build up main pressure, truck off, then key on and dump the suspension and drain the tanks. PS, I could be wrong. It happened once before. ;-) 2007 Volvo 880 2014 Palomino Sabre 36qbok Link to comment Share on other sites More sharing options...
Alie&Jim's Carrilite Posted July 25, 2016 Report Share Posted July 25, 2016 My air accessories will not work until 70psi is in the tanks. Then the seats, airbags, and such will air up. But I can dump my bags and leave the dump switch open, turn the key off and they stay deflated.

RickW Posted July 26, 2016 Report Share Posted July 26, 2016 On my truck if the dump switch is on and the bags are already deflated, when the truck is turned on the bags will inflate at 60~70psi then deflate.

sclord2002 Posted July 28, 2016 Report Share Posted July 28, 2016 If my air pressure is low on my gen 2, the rear suspension won't dump.......I have to run engine to build up air pressure for the bags to dump.
