yeah soapy water a lot of the time u can hear it. its normally in teh fold of the bag. basic run down....

jack the truck let the axels hang.. stab the bag to get the air out. they twist off disconnect the air line and do the process backwards..

go to gmpartsdirect.com to get the bags. they r like 90 bucks on there
