Volkswagen ID.4: Monitoring the tightening torque

The correct wheel bolts must always be used for each vehicle model, and these bolts must always be tightened to the correct torque. The wheel bolt tightening torque must be checked regularly with a functional torque wrench. In addition, the tightening torque must be checked immediately after each wheel change with a functional torque wrench. If the wheel bolts are not tightened enough to meet the specification, the wheel bolts and rims could come loose while driving. Exceeding the tightening specification could damage the wheel bolts and threads.

Wheel bolts that are corroded and difficult to turn must be replaced and the threads in the wheel hub must be cleaned before checking the tightening torque. Never grease or oil the wheel bolts and the threads in the wheel hub.

Wheel bolt tightening specification

The tightening torque of the wheel bolts is specified in the chapter on replacing wheels (→ Wheels and tires).

WARNING

If the wheel bolts are not tightened enough to meet the specification, the wheel bolts and consequently the wheel could come loose while driving. Exceeding the tightening specification could damage the wheel bolts and threads.

Wheel bolts that are tightened incorrectly or missing could cause you to lose control of the vehicle and lead to serious accidents and fatal injuries.

• Always tighten the wheel bolts to the correct tightening torque. If you do not have a torque wrench, tighten the wheel bolts with the lug wrench and then have the tightening torque checked as soon as possible by an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
• Never drive with missing or loose wheel bolts.
• Always use wheel bolts that are correct for the rim and the vehicle model.
• Never grease or oil the wheel bolts and the threads in the wheel hub. Even when tightened to the specification, the wheel bolts could become loose while driving.
• Ensure the wheel bolts and threads in the wheel hubs are clean, easy to move and free of oil and grease.
• Never loosen the bolts on rims with a bolted rim ring.
