My refrigerator stands on the floor unevenly. Its slant is small but enough to make the motor produce unpleasant noises. If I manually tilt the refrigerator a little bit, the noise disappears.
Unfortunately the refrigerator's 'legs' are not adjustable. I tried putting various pieces of plywood under corners. It helps a bit, but finding the right thickness of such piles is hard, and so far I failed to achieve a satisfactory position of the fridge.
What could I use to gradually adjust the vertical position of a large heavy box which is the refrigerator? Some kind of miniature jack screw?
The distance from the floor is about 1/4".
