• Remove tire
  
• Remove cotter pin
  
• Replace tire and lower car to ground
  
• Apply parking brake and car in Neutral
  
• Loosen up castle nut with 36mm socket and long handlebar
  
• Jack up and support vehicle again and release parking brake
  
• Remove tire, castle nut and drum brake

Outboard

Inboard

• Pry out inboard and outboard sealing rings. From inboard side drive out outboard bearing with soft punch (brass) and hammer. Now shim ring (if any) and spacer sleeve can be removed from outboard side. Now can easily remove inboard ball bearing with punch and hammer. It is imperative that circular shim and spacer sleeve for each wheel kept separate if rear wheels bearings removal done at once.
  

• Wipe inside with paper towels and spray inside with brake cleaner.
  

• New bearings and seals
  

• Next, Pack bearings with grease and grease sealing rings lip
  
• Install inboard bearing. I used 1-1/2” dia. PVC coupling and plug to drive bearing in against bearing bore stop.
  

• Coat sleeve spacer outside with 35 grams grease and then insert sleeve to the cavity from outboard.
  

• Insert shim ring then, install outboard bearing making sure it is seating against shim
  

• Install inboard and outboard seals
  
• Insert axle shaft from inboard side all the way in
  
• Install hub/ driving flange. May need to use hammer on face of hub to seat it in
  
• Tighten castle nut with 36mm socket
  
• Replace drum brake
  
• Install tire and lug nuts
  
• Put rear wheels on ground
  
• Apply hand brake
  
• Secure front and back of rear tire with objects to prevent it from rotational movement
  
• Tighten castle nut to specified torque
  

• And for last time Jack up and support vehicle
  
• Remove tire
  
• Install cotter pin and bend tabs
  
• Replace output shaft / CV shaft to axle shaft flange
  
• Put tire back on and tighten lug nuts
  
• Lower the car and torque lug nuts to 65 ft-lb
