changed Level valve. Volvo VNL

level value went bad after 600k miles.
cab didn't feel like how it should ride anymore. so we changed bad cab bushings, all new shocks, new cab shocks, and now new level valve.
level valve controls the cab from rocking too much and bouncing too much. It hooks up to the air lines to your cab air bags.
