    Need some help?? I have a rear vibration that is felt mainly with acceleration or when the jakes are on, replaced airbags due to a leak and age(wear). I know there could be several different things just didn’t know if someone else may have had the same issue before digging into it.

    Check ride height, u-joints and carrier bearings-make sure all suspension parts are tight.

    Have a dyno done.

    I drive a cat that did that. New fuel injectors to fix the problem.
