Product review (4 stars): Works great in our Kenmore !
We have a Kenmore 106.556xxxx side by side, and this did the trick !  It now works great.  The previous drawer slide/guide always seemed to fall off on us, and I would have to put it back on.  Then I noticed a small crack in the drawer slide, and decided to buy this and replace it.  I am very glad I did this.  After putting in this new slide for $11 and 10 mins of time, I now remember how nice the drawers are supposed to glide.  Very smooth !

We would have given this 5 stars stars if we didn't have to get the dremel out to remove the extra two small circle spots from the slide unit (See picture).  I found a youtube video of a serviceman putting this in with the two extra circles still on the slide, but it took too much effort to slide it and I was afraid I was going to break something.  So, I just used a dremel to remove the two circle bumps that were not on the original drawer slide to make it an exactly like the original that came with the refrigerator.

It helped a lot to remove the entire shelf from the refrigerator, turn the unit upside down on the counter, and replace the slide on the counter vs. trying to do this inside the refrigerator.  Bonus: I found one of my lights in the very back of the refrigerator was burned out when I removed the shelf for this repair - so now the inside is also brighter !
