- Use a torque wrench to tighten the wheel nuts in a star or crisscross pattern.
- Apply the torque in multiple stages to ensure even tightening:
- Stage 1: Set the torque wrench to 30% of the recommended torque settings.
- Tighten each wheel nut in the specified pattern.
- Stage 2: Increase the torque wrench setting to 60% of the recommended torque settings.
- Repeat the tightening process in the specified pattern.
- Stage 3: Set the torque wrench to the full recommended torque settings.
- Complete the final tightening in the specified pattern.
Final Checks
- After tightening the wheel nuts, visually inspect each wheel to ensure they are securely fastened.
- Double-check the torque settings using a torque wrench to verify the correct tightness.
- Repeat this process periodically, especially after tire rotations or when reinstalling wheels.
By following these guidelines and using the recommended torque settings, you can ensure the safety, performance, and longevity of your Jaguar S Type’s wheels. Properly tightened wheel nuts provide peace of mind and a smooth driving experience.
