Practical Recommendations for Lug Nut Maintenance
Maintaining the proper torque on your lug nuts is essential for the safety and performance of your 2017 Subaru WRX. Below are actionable recommendations that every vehicle owner should consider.
Importance of Using a Torque Wrench
Using a torque wrench is crucial for achieving the correct tightness of lug nuts. Here’s why:
– Precision: A torque wrench allows you to apply the exact amount of torque specified by the manufacturer. This precision helps prevent both over-tightening and under-tightening.
– Safety: Properly torqued lug nuts reduce the risk of wheel detachment, which can lead to serious accidents.
– Longevity: Consistent use of a torque wrench can extend the life of your wheel studs and lug nuts, saving you money on replacements.
Avoiding Impact Tools
While impact tools can speed up the process of removing and tightening lug nuts, they can also cause significant damage if not used correctly. Here are some reasons to avoid them:
– Over-Tightening: Impact wrenches can easily over-tighten lug nuts, leading to stripped threads and potential wheel failure.
– Inconsistent Torque: Unlike a torque wrench, impact tools do not provide consistent torque levels, which can compromise safety.
– Damage to Components: The high torque levels from impact tools can damage brake rotors and wheel components.
Wheel Nut Torque Chart
Here’s a comprehensive chart for the wheel nut torque specifications for the 2017 Subaru WRX across different trim levels:
| Trim Level | Front Wheel Torque (ft/lbs) | Front Wheel Torque (Nm) | Rear Wheel Torque (ft/lbs) | Rear Wheel Torque (Nm) |
|---|---|---|---|---|
| WRX Base | 90 | 122 | 90 | 122 |
| WRX Premium | 90 | 122 | 90 | 122 |
| WRX Limited | 90 | 122 | 90 | 122 |
| WRX STI | 90 | 122 | 90 | 122 |
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 new tire installations or rotations. A good rule of thumb is to check them after the first 50-100 miles of driving.
– Proper Tightening Sequence: When tightening lug nuts, always follow a star pattern. This ensures even distribution of pressure across the wheel, reducing the risk of warping or uneven wear.
– Best Practices for Securing Wheels:
– Clean the wheel hub and lug nut threads before installation to ensure a proper fit.
– Use a torque wrench to tighten lug nuts to the specified torque level.
– Avoid using lubricants on the threads of lug nuts, as this can affect the torque readings.
Consulting Your Manual or Seeking Professional Assistance
Always refer to your vehicle’s owner manual for specific torque specifications and maintenance guidelines. If you’re unsure about performing any maintenance tasks, don’t hesitate to seek professional assistance. A qualified mechanic can ensure that your lug nuts are properly torqued and that your vehicle is safe to drive.
By following these recommendations, you can help ensure that your 2017 Subaru WRX remains in optimal condition, providing you with the performance and safety you expect from this iconic vehicle.
