Installation Notes and Tips

Confirm the bearing type, cone bore, and cup dimensions against the original part before installation. Clean the hub, spindle, and mating surfaces thoroughly, and inspect the cup and cone seating areas for scoring or wear. Proper bearing preload and lubrication are critical for long service life, so follow the vehicle service procedure for the specific Mercedes-Benz G-Class or Nissan dual rear wheel application.
