Product review (5 stars): Fast and easy repair and more durable than original
This kit has replacement wheels and adjusters for both sides of the top dishwasher rack. They are factory parts, not third-party. The original plastic adjusters and wheel hubs were flimsy and broke. The same happened to my daughter who ended up having a repairman install this same kit for a total of over $100. This kit is easy to install yourself. The box has just parts and no instructions but refers to a web site where you enter the part number and it comes up with the instruction sheet. There are also multiple youtube videos available to do this.  It took me about 15 minutes (it would be 5 minutes to do it again!) and was easy and straightforward to do. The kit uses torx screws, but includes an adapter for philips-head to torx, so you can probably use a screwdriver that you already have. That philips-head screwdriver is the only tool required. With prime delivery, this is likely faster and is definitely far less expensive than scheduling a repair. I would highly recommend this kit over the many third-party replacements of the original plastic adjusters.
