Replacing table slides requires minimal effort. Measure the old one, find new ones that comport to the size, and simply unscrew the old and screw in the new. IMPORTANT! Do NOT rely on the old screws to fit the new slides. It is SO EASY to screw through the surface of the table top. (No, I did NOT do this!) BE SURE to measure for thickness and even then check with the first screw in place. The quality of the slides offered here is good so you can pretty much be guaranteed that all the holes are he same. To be certain, however, you may want to double check. All it takes is one to be 1/4 deeper for some reason and you've got a problem. Any good professional cabinetmaker would be sure to check that.
