2018 Subaru Impreza Lug Nut Torque Specifications
Why Lug Nut Torque Matters
- Properly torquing the lug nuts on your 2018 Subaru Impreza is crucial for your safety and the longevity of your vehicle.
- Incorrect lug nut torque can lead to loose wheels, which can cause vibrations, poor handling, and even wheel detachment.
- It is important to follow the manufacturer’s recommended torque specifications to ensure the wheels are securely fastened.
Understanding Lug Nut Torque
- Lug nut torque is the amount of force applied to tighten the lug nuts on a wheel.
- It is measured in pound-feet (lb-ft) or Newton meters (Nm).
- Applying the correct torque ensures that the lug nuts are tightened to the appropriate level, preventing them from loosening over time.

How to Properly Torque Lug Nuts
- Start by ensuring that your Subaru Impreza is parked on a level surface and the parking brake is engaged.
- Locate the lug wrench and the jack that came with your vehicle.
- Loosen the lug nuts on the wheel you want to remove by turning them counterclockwise, but do not remove them completely yet.
- Position the jack under the designated jacking point of your Subaru Impreza and raise the vehicle until the wheel is off the ground.
- Remove the lug nuts and take off the wheel.
- Clean the wheel hub and the mounting surface to ensure proper contact.
- Place the new or repaired wheel onto the hub and hand-tighten the lug nuts until they are snug.
- Using a torque wrench, tighten the lug nuts in a star or crisscross pattern to the specified torque for your wheel size.
- Double-check the lug nut torque after driving a short distance to ensure they are still properly tightened.
Final Thoughts
Properly torquing the lug nuts on your 2018 Subaru Impreza is a simple yet essential maintenance task that should not be overlooked.
By following the manufacturer’s recommended torque specifications and using a torque wrench, you can ensure the safety and longevity of your vehicle’s wheels.
Remember to periodically check the lug nut torque to prevent any potential issues and always consult your vehicle’s owner’s manual for specific instructions and torque values.
