Bought a wheel bearing and hub replacement kit for my 2005 Volkswagen Passat. I was disappointed when the screw fell apart on the first try. I realized that I had used a larger diameter shim than the knuckle. After figuring out the screw size (3/4-16" x 6" Grade 8), I was lucky enough to find it at one of my local screw and bolt stores. The toolbox worked great for me afterwards. The head of the original screw was slightly smaller than the ones I bought (27mm and 32mm). I give 5 stars even if it didn't work for me the first time, but that was my fault.
