Trick with 4 Post Lift
I recently purchased a 4 post lift. I agonized over a 4 post or 2 post lift. I wanted to be able to get the wheels off with the car on the lift. I came up with this. See pics. It is made from the jacking beam that came with the lift. I hole sawed (2) 1.5" holes 24" on center. Then welded 1.5" x .095" x 6" tube in the holes. I used 1.25" all thread with heavy nuts and welded 4" of 2"x2" angle to the top, V down. The all thread is long enough to be sticking out the bottom of the lift when the car is at ride height and the jack stands are against the axles. I actually made another jacking beam from a piece of 6" channel, so I had one front and rear.
I drive the car on the lift. Raise it a foot or so. Place the jacking beam and stands under the axles. Lower the lift and the stands catch the car and allow the ramps to drop out from under the car. Then adjust the nuts down on the all thread. Raise the lift back up and the wheels are clear of the ramp, supported on the stands. I liked this trick so well I made 2 more jacking beams with supports at different centers so I could support the frame from the lift also, for suspension work.
Both my cars are straight axle front and rear, but this trick could probably be adapted to A arm suspension. It takes me longer to type it than it does to do it.
I thought this was pretty neat. Don't know if it's has been done before, just thought I would share.
