    on my KW t2000 1 of 2 air bags that holds the cab has crack and leaking air and the cab doesn't inflate, just being held by shocks and rubber pad. Can someone tell me the proper way on how to remove that bag. It has air fitting on the bottom and 1 bolt on top. I was thinking about:
    1. unscrew bolt & unplug air line
    2. block that air line
    3. turn on the truck and let the other bag inflate
    4. using leveling valve raise cab even more
    5. remove bag upwards.

    please correct me if i am wrong, or if i need to add more steps

    I think you can do it that way, just be sure to block the cab up before you start working under it, I wouldn't trust that one bag holding it up with my hands and arms underneath it.

    Many times you can just take a pair of pliers, and squeeze the line to the leaking bag and the other bag will lift it, then you inset the block, and change the bag. It gives more room. If you got it done good for you!
