Product review (1 stars): Didn't buy it, I krazzy-glued mine back together!
After reading the horrible reviews and looking at a minimum of $40 and a holiday weekend of no dishwasher, I took matters into my own hands.

I krazy glued the wheels directly to the plastic frame or what was left of the stub.  It is a little bit harder to slide the drawer out, but it seems to work for now.

Hope this helps folks who are frustrated with this silly piece of hardware!
