If you have a vibration while jaking you have a issue with one of the jake solenoids or jake rocker it self... Here lately we have been replacing alot of jake rockers just for this same issue. Go from stage one to stage two see if you can feel that its working. If you can tell a slight change then more than likely you need new jake rockers. We are in the process of trying to find a way to test them off the truck so we are not replacing all of them all the time. However, if one or two has failed others are not far behind...
