Wheel lug torque pattern
Always tighten lug nuts in a star or cross pattern to ensure even seating of the wheel. Never tighten them in a circle.
Brake torque notes
Brake caliper and bracket bolts are critical fasteners. Always use a calibrated torque wrench and follow the manufacturer's recommended sequence. Using thread locker on these bolts is recommended.
Why torque matters
Proper torque is critical for both safety and performance. Undertorqued fasteners can loosen over time, leading to component failure. Overtorqued fasteners can strip threads or damage components, also leading to failure. Always use a calibrated torque wrench for critical fasteners.
Disclaimer: This information is for reference only. Critical fasteners should always be verified in the OEM service manual.
