Good tricks! If you cant get a ratchet or socket on a stubborn bolt, only the box end of a combo wrench, put the box end of another sideways on the open end side of the wrench. put it on the side that you are putting torque against. Works like a cheater.

the top half of a floorjack handle makes for a good cheater bar.

Dont feel like leaning down to pump the floorjack? Use your feet to move the handle up and down.

If you cant break something loose with your hands and you have room, push with your feet. You generally have more lower body strength than with your arms.
