Once you have repacked the bearings, replaced the grease seal, and have the hub back in place, and the keyed washer and clamp nut back on the axle, ready to be tightened down ... rotate the brake disk and hub several turns back and forth to distribute the grease evenly ... with a Crescent wrench or open-end wrench tighten the clamp-nut until all play is taken up, and loosen slightly while trying to 'wiggle' or move the keyed washer slightly back and forth with a large flat-bladed screwdriver (1/4" to 3/8" blade)... when you can 'just' move that washer back and forth with moderate, but not light force -- 'a twist of the wrist' the play will be in the 0.001" to 0.003" range -- a very difficult direct measurement without a dial indicator, magnetic or clamping holder and heavy base of some sort!!! You can verify the 'correct' ammount of play by mounting your wheel and tire, lowering the front end off the jack stands, and 'rocking' the top of the tire back and forth by grabbing the tire at the 11 :00 and 1:00 o'clock positions and checking foe LESS then 1/8" 'play' at the top of the tire. About 1/16" would be ideal! At that level of play, any excessive play at the steering wheel has to be from ball joints, steering rack play, tie-rod ends, or steering column u-joint play! Good Luck!
