Product review (5 stars): Great Kit, don't buy the T10 Screwdriver
This is the kit you need to finally solve the broken wheels and plastic on the top rack.  Watch the YouTube video - the instructions are hard to follow.  It is a 10 minute job at most.  You DON'T need the T10 Torx screwdriver, a Philips head to T10 converter comes with the kit.  There are only 4 screws to tighten and the adapter works well for them.  Absolutely worth the price.
