Replacing the hardware in pull out shelves may be necessary from time to time. The drawer slides can become damaged with regular use, and the handles and glides can become loosened. Replacing the hardware isn't difficult, you just need to have the right materials and a little patience.
Step 1 - Remove Existing Hardware
If you are working with a shelve that pulls out of a cabinet, or a drawer, you have to remove the entire shelf. Pull the shelf towards you until it stops, then lift up slightly to unlock the slide mechanism. From here you will be able to remove the shelf entirely. Check the tracks on the cabinet side, and remove the slide bars. If the wood underneath is damaged, you may as well remove it and prepare to replace that as well. It's not common for the blocks of wood attached to the slide to become damaged, but it may happen. Remove the slides from the shelf as well.
Step 2 - Measure the Materials
Measure the length, height, and width of both sets of slides. You will need these to purchase the new ones. If you prefer, you can take the old ones with you to make the purchase.
Step 3 - Install Shelf Slides
Install the slides on the shelf first. Line up the new slides in the marks left by the old ones. Usually you won't need to drill new holes. Place the screws in the existing holes, and hand tighten them. If you use a drill it's easy to over tighten the screws. Don't tighten them all the way down just yet.
Step 4 - Install Cabinet Slide Track
With the shelf slides installed you can begin to work on the cabinet slide tracks. Use the same method as you did with the shelves, securing the tracks with a handheld screwdriver. Don't completely tighten these either.
Step 5 - Check for Alignment
Place the shelf in the slide track just to check for proper alignment. If it's not aligned, you can make minor adjustments as needed. Don't tighten the screws until you have it completely aligned.
Step 6 - Drill it Down
Now that you have the alignment settled, you can remove the shelf and use a drill to finish tightening the screws. Do the same thing for the tracks in the cabinet.
Step 7 - Apply Oil
Use a household spray lubricant to oil the tracks. Don't use too much, just a very small amount. This will keep the tracks from rusting and prevent noise from the sliding action.
Step 8 - Replace Handles or Pulls
If you want or need to replace the outer hardware, you can do this with the shelf in place. Pick out the handles or pulls you want, and simply remove the old ones, and screw in the new ones. Use a drill to tighten them in to place.
