Adjusting a wheel bearing on your Isuzu D-Max depends on whether your vehicle has sealed or serviceable bearings:
Sealed bearings
Modern Isuzu D-Max pickup models typically come with sealed wheel bearings. These bearings are pre-lubricated, sealed, and designed to be maintenance-free. They cannot be tightened or adjusted. When wear or failure occurs, the entire bearing unit must be replaced.
Serviceable bearings
If your Isuzu D-Max is an older model equipped with serviceable (adjustable) wheel bearings, these can be adjusted. Adjustment involves tightening the bearing nut to the manufacturer’s specified torque, then backing off the nut as directed (either by a specific angle or to achieve a certain level of play), and securing it with a cotter pin.
Improper adjustment of serviceable bearings can lead to serious issues, including overheating or instability. It’s recommended to consult the Isuzu D-Max’s service manual or a professional mechanic for precise instructions and to ensure the safety and integrity of the wheel bearing adjustment.
