The Mitsubishi Pajero, a legendary SUV known for its ruggedness and off-road capabilities, has captured the hearts of adventure enthusiasts worldwide. Since its inception in 1982, the Pajero has been a symbol of power, reliability, and versatility. With its robust design and advanced features, this iconic vehicle has become a trusted companion for those seeking thrilling escapades on both paved roads and challenging terrains.
Why Wheel Nut Torque Matters
When it comes to maintaining the performance and safety of your Mitsubishi Pajero, paying attention to even the smallest details is crucial. One such critical aspect is the wheel nut torque, which refers to the amount of force applied to secure the lug nuts that hold the wheels in place. While it may seem like a mundane task, ensuring the correct wheel nut torque is essential for several reasons:
- Preventing Wheel Loosening: Properly torqued lug nuts provide the necessary clamping force to keep the wheels securely attached to the vehicle. Insufficient torque can lead to wheel loosening, increasing the risk of accidents and compromising vehicle control.
- Ensuring Wheel Alignment: Incorrect wheel nut torque can result in uneven pressure distribution on the wheel hub, leading to misalignment. This can cause uneven tire wear, reduced handling performance, and potential damage to suspension components.
- Promoting Wheel Longevity: Over-tightening lug nuts can exert excessive stress on the wheel studs, leading to thread damage or even stud failure. Conversely, under-tightening can cause the wheels to wobble, leading to premature wear and tear.
- Enhancing Fuel Efficiency: Properly torqued lug nuts ensure optimal wheel alignment, reducing rolling resistance and improving fuel efficiency. This not only saves you money at the pump but also contributes to a greener environment.
By understanding the significance of wheel nut torque and adhering to the recommended specifications, you can ensure the longevity, performance, and safety of your Mitsubishi Pajero. In the following sections, we will delve into the specific lug nut size and torque specifications for this remarkable vehicle, providing you with practical recommendations for maintaining your wheels effectively.

Actionable Recommendations for Maintaining Lug Nut Torque
1. Regularly Inspect Lug Nuts
Make it a habit to visually inspect the lug nuts of your Mitsubishi Pajero regularly. Look for any signs of looseness, rust, or damage. If you notice any issues, promptly address them by tightening or replacing the lug nuts as necessary.
2. Use a Torque Wrench
Invest in a reliable torque wrench to ensure accurate and consistent torque application. Avoid using impact wrenches or other power tools, as they can easily over-tighten or under-tighten lug nuts, leading to potential problems.
3. Follow the Manufacturer’s Specifications
Always refer to the manufacturer’s recommended torque specifications for your specific Pajero model, year, and trim level. These specifications are designed to ensure optimal performance and safety, so it’s important to adhere to them.
4. Torque in a Star Pattern
When tightening lug nuts, follow a star or cross pattern rather than going around in a circle. This helps distribute the torque evenly and ensures proper seating of the wheel on the hub.
5. Re-Torque After Wheel Installation
After installing new wheels or performing any maintenance that involves removing and reinstalling the wheels, re-torque the lug nuts after driving a short distance. This helps account for any settling or changes in torque due to initial wheel seating.
6. Check Torque Periodically
Periodically check the lug nut torque to ensure they remain properly tightened. This is especially important after driving on rough terrains or long distances, as vibrations and other factors can cause the lug nuts to loosen over time.
By following these recommendations, you can maintain the correct lug nut torque for your Mitsubishi Pajero, ensuring the safety, performance, and longevity of your vehicle’s wheels.
