refrig not level

[m0mm0m]

The refrig has two adjusting screws in front only. left and right ‘front’ wheels. The floor is level in front between left and right legs. Floor tilts in back of floor where rear wheels go.So right rear wheel is lower than left rear. I cannot adjust the rear wheels, so that is why I made the double shim contraption thing. But it is difficult to push refrig back onto shim because it is so narrow, whenever I pull it away from wall to clean, etc.
