Remove the front axle nut, remove the Lock washer, remove the outer bearing ( the one that is facing you, screw the axle nut back on a couple of turns. And with a downward motion, pull the brake drum off. you will pull the inner bearing and grease seal out. Remove all the old grease from the bearing. Install new grease, using a bearing packer or you can do it by hand. Make sure to get new grease inside the bearing and race also put new grease around the outer edges of bearing. Reinstall every thing. Use a new inner grease seal. Tighten the axle nut until the drum will not turn, and then back off the axle nut to about 1 1/2 turns. Install a new cotter key in the slots of the axle nut. ( The nut slots have to align up with the hole in the axle ).

Okie - Dokie-- are you sure about backing the nut off 1 1/2 turns? Seems like a bit much. I was thinking you should loosen the nut 1- 2 flats (Flat sides) on the nut until the hole lines up.

You don,t want too much free play.

I am sorry, you are correct. Usually 1/2 turn to 1 1/2 turn depending on bearing wear. But then, if the bearing is that worn. It also should be replaced.
