I used two link bar ends/bushings for the pivot/hinge...And I think it is the rubber twisting/turning that is making the noise...You can hear the same sound when I raise the rear of the trucks because of the bushings in the 2 link bars. Or maybe it is the airbag slowly filling with air.
@@TemperDriven I think it might have to do something with the airbag expanding cuz it's quiet when it's lowering... maybe because the airbag is pushing up, but it's being forced into an angle?
