Wheel Nut Torque Chart
| Trim Level | Year | Front Wheel Torque (ft/lbs) | Front Wheel Torque (Nm) | Rear Wheel Torque (ft/lbs) | Rear Wheel Torque (Nm) |
|---|---|---|---|---|---|
| SV | 2018 | 140 | 190 | 140 | 190 |
| SL | 2018 | 140 | 190 | 140 | 190 |
| Pro-4X | 2018 | 140 | 190 | 140 | 190 |
| Platinum Reserve | 2018 | 140 | 190 | 140 | 190 |
Importance of Using a Torque Wrench
Using a torque wrench is essential for achieving the correct torque specifications. Here’s why:
- Precision: A torque wrench allows you to apply the exact amount of torque needed, preventing over-tightening or under-tightening.
- Safety: Proper torque reduces the risk of wheel detachment, ensuring that your vehicle remains safe to drive.
- Consistency: Using a torque wrench ensures that all lug nuts are tightened uniformly, which is crucial for maintaining wheel alignment and performance.
Avoiding Impact Tools
While impact tools can be convenient, they are not recommended for tightening lug nuts. Here’s why:
- Risk of Over-Tightening: Impact tools can easily apply excessive torque, leading to damaged threads or warped brake rotors.
- Inconsistent Torque: These tools do not provide a consistent torque level, which can result in uneven tightening.
- Potential for Damage: Over-tightened lug nuts can be difficult to remove later, potentially causing damage to the wheel or lug nut.
Maintenance Tips
To ensure the longevity and safety of your wheels, consider the following maintenance tips:
- Periodic Torque Checks: It’s advisable to check the torque of your lug nuts periodically, especially after having new tires installed or after a long trip. This helps ensure that they remain securely fastened.
- Proper Tightening Sequence: Always tighten lug nuts in a crisscross pattern. This ensures even distribution of pressure and helps prevent warping of the wheel.
- Best Practices for Securing Wheels:
- Clean the wheel hub and lug nut threads before installation to ensure a proper fit.
- Use a lubricant on the threads if recommended, but avoid over-lubricating, as this can affect torque readings.
- Always refer to the vehicle’s owner manual for specific torque specifications and guidelines.
Consulting Manuals and Seeking Professional Assistance
If you are unsure about any aspect of wheel maintenance, it is always best to consult your vehicle’s owner manual. The manual provides specific guidelines tailored to your vehicle model. Additionally, if you are not comfortable performing these tasks yourself, seeking professional assistance is highly recommended. A qualified mechanic can ensure that your wheels are properly secured and that your vehicle remains safe and reliable on the road.
