With the front spindle nut adjusted properly, there should be a slight amount of endplay on a modern RWD vehicle, as felt by grasping the rotor and moving it laterally. It should move no more than 0.001-0.008 inch. To make this adjustment, spin the rotor several times (more than 8 or 10) while carefully tightening the adjusting nut to zero preload. Then back the nut off only enough to install a new cotter pin into the first available slot. Check the endplay. Because the adjusting nuts have six sides and the spindle is drilled both horizontally and vertically, very accurate bearing adjustment is possible.
