I know a bunch of people here have the speedy lift vehicle lift. And that some have even moved it from one vehicle to another. Well km having an odd problem with mine, it's lifting off the vehicle floor. Where and how is it attached to the vehicle floor? At first the back/second section was occasionally lifting a bit off the floor whole raising my chair into the vehicle. Once the chair was raised enough the weight pushed it back down. But now it appears the entire thing is no longer affixed to my vehicle floor, as the whole thing lifts up instead of my chair being raised.
