Chrobar,
Yup, for sure. I am using those collared washers but they dont seem to be doing what they should. I can see that the screw is supposed to lock down on that washer and allow the steering knuckles to still move freely. In my case... the screws still hit the plastic hub carriers! Plus the geometry of the mounting screws for the knuckes in relation to the hub carriers seems to be off and that seems to be causing some of the binding. VERY FRUSTRATING! Not sure but I have used a lot of blue loctite and backed the screws off enough to let the knuckles move more freely. I am expecting to lose the screws during driving now. Weird.
