I am a true DIY girl, and this repair wasn't terribly difficult, although it took some analysis and time to figure out and complete the installation. Appliance Parts Pros often has helpful videos, but I couldn't find anything for this part, and there were no instructions included. First, I removed the two baskets/drawers from the bottom freezer compartment. Then, I removed the left and right cradles (which hold the upper freezer basket), and lastly, after pressing the plastic release clip on both the left and right side "Adapters", I was able to remove the drawer slides, which at this point were still attached to the freezer door via the white metal drawer slide brackets. Next, I removed the rack shaft, the horizontal metal rod which connects the left and right white plastic gears, by gently spreading the left and right bracket assemblies. Then, I removed the two screws located on each side of the freezer door (inside surface) to which the white metal drawer slide brackets were attached so that I could get the freezer door front out of the way. Here's where it got a bit tricky - the white metal drawer slide brackets were riveted to the existing faulty drawer slides, and the only way that I could separate these two parts (one set on the left and one set on the right) was to drill out the one rivet on each side. Once the faulty drawer slides were now removed on each side, I was ready to reassemble everything. First, I needed to remove the plastic gear from each of the old drawer slides since the gears would be needed with the new drawer slides - this was tricky also. The white gear is attached to a plastic bushing, which in turn is attached to the drawer slide, and separating the gear from the bushing was challenging. I turned the bracket over to the back side, the side which attaches to the inside freezer compartment. The bushing is attached to the moving portion of each drawer slide (not the fixed portion that mounts to the inside of the freezer). Fortunately, there is a large oblong hole on the fixed portion of the slide that can be lined up with the back of the bushing (a peek-a-boo hole), and by inserting a slot screwdriver into the back of the bushing through that hole, I was able to release the gear on each side. As the new drawer slides came with new white plastic bushings, there was no need to remove the old bushings from the damaged slides. First, I attached the old gears to the new drawer slide - with a gentle push, each one snapped into place. Next, I attached the white metal drawer slide bracket to each of the new drawer slides, but since I don't own a rivet gun, I used a very small screw to attach the new drawer slide to the existing white metal drawer slide bracket. A word of caution - the screw head must be on the outside of the drawer glide assembly (I learned this by trial and error) as the screw shaft will impede the drawer glide function otherwise. (A small stainless machine screw with a nut will do the trick - I prefer stainless to avoid corrosion issues.) Next, I reattached the freezer drawer front to the white metal drawer slide bracket using the same two screws that I had previously removed from each side. Now it was time to insert the horizontal rack shaft which connects the left and right gears. VERY IMPORTANT - the left and right gears have a set of four shorter teeth on each side that must be lined up with one another in mirror-like fashion (if not, the gears can bind and cause wear and tear on the ball bearings of the new drawer slides, which might necessitate having to do this project all over again!!) Next, insert the new metal drawer slides into place until the plastic clip on each side snaps into place. Double check that the gear teeth on each side are line up. If not, then remove the entire assembly by pressing the white plastic release clips on each side, remove the metal rack shaft, and then rotate the gear teeth accordingly until both sides line up exactly and repeat the final installation steps. My new drawer glides are fabulous, and my freezer drawer finally glides like silk!! Just a final note - the drawer glides have a self-closing feature, but in order for this feature to work properly, the black plastic "button" on the inside surface of each drawer glide, to which a spring is attached, must be in the forward position. If the black button is pressed, the spring is then released and the self-closing feature is deactivated. To reactivate the self-closing feature, pull the black button and its attached spring back to the forward position until it snaps into place.
