I just had the cab leveling valve replaced. Was leaking air pretty bad. I'd wake up in the morning to 2 empty air tanks. However, it DID NOT fix the whole problem. My cab goes up-n-down and up-n-down while shut down/sleeping. Like an East LA low-rider with bounced shocks. Seems to me one of the air bags is bad also? And it rumbles like crazy like bongos from that side while driving. Shop doesn't know/care about fixing it. A week at the dealer to replace the airbag? Thoughts? It took stopping at 5 - FIVE- terminals to get the valve replaced. Probably never get the bag/problem fixed - or any sleep!
