The specific tightness to which the wheel fasteners of a Toyota Highlander should be secured is a critical element in vehicle maintenance. This value, typically measured in foot-pounds (ft-lbs) or Newton-meters (Nm), ensures the wheel is properly affixed to the vehicle’s hub. Applying the correct amount of force is essential for safe and reliable operation. For example, under-tightening can lead to wheel loosening and potential detachment, while over-tightening can damage the studs or distort the brake rotor.
Adherence to the manufacturer’s recommended specification offers several advantages. It prevents wheel separation, which can result in accidents. It also maintains the integrity of the wheel studs, preventing premature failure due to excessive stress. Historically, incorrect tightening procedures have been a contributing factor in wheel-related incidents, highlighting the importance of following prescribed torque specifications and using a calibrated torque wrench.
