1. Remove one original wheel nut or wheel bolt from each wheel of your vehicle. When replacing a wheel later, remove the wheel lock first and install it last.

IMPORTANT – Before installing the wheel lock, please always check that the McGard wheel lock has the same thread, seat, and shaft/overall length as the original nut/bolt! 

2. Install a McGard wheel lock by hand on each wheel. Make sure that the key pattern is firmly and securely engaged into the lock pattern. Using the provided key and a torque wrench, tighten each McGard wheel lock with the torque specified in your vehicle's manual. Apply axial pressure on the torque wrench in direction of the lock to prevent the provided key from slipping or jamming. Turn the wheel by hand to check whether it rotates freely and without impediment. Verify that the minimum thread engagement into the hub assembly is 5,5 revolutions of the fasteners. Some wheel lock bolts are a 2-piece design. Make sure that the floating seat washer is attached to the lock bolt before installing. McGard does not recommend the use of oil, grease or lubricants on threads.

3. Turn the wheel by hand to check whether it rotates freely and without impediment.


How to install McGard Wheel locking bolts/nuts?

IMPORTANT Do not use an impact spanner: this can damage the McGard wheel lock, key, and your vehicle. After the first fifty kilometres, please check again that the McGard wheel lock sits properly, and if necessary retighten it with a torque wrench. So that you can access your key in the event of a wheel change, we recommend that you keep your key, the original nuts/bolts for your vehicle, and these installation instructions (with your personal code number) in the resealable packaging at a secure place in your vehicle.

Removing tight wheel lock nuts/bolts

CAUTION You are recommended to wear protective gloves and goggles when removing tight wheel locks!

Tighten all hex bolts on the wheel with the tight wheel lock to reduce the pressure on this. When tightening the standard fasteners, make sure that you do not damage the thread. 

Remove the wheel lock with the McGard wheel lock key. Use a suitable loosening tool, e.g. an impact spanner, spider spanner, or ratchet. When loosening, you must always use the loosening tool to exert pressure on the wheel lock's and wheel lock key's longitudinal axis. This ensures that the key engages exactly in the coding and does not slip or twist out. 

NOTE Contrary to the instructions for installing the wheel lock, an impact spanner is a suitable tool for removing wheel locks that are too tight. When the first attempt fails to loosen the wheel lock, try again. The impact spanner must exert an adequate torque.

Make sure that the loosening tool you use is not applied obliquely. Oblique applications can cause the wheel lock key or codings to deform or fracture. 

When the loosening procedure described above fails, please loosen (on four hole rims) the standard fastener opposite the wheel lock. On five hole rims, loosen the two standard fasteners opposite the wheel lock. After loosening, repeat the procedure described under (2). 

NOTE When the wheel lock fails to detach, please call for further details our McGard services hotline on 00800 25993400 (free of charge)

After loosening the wheel lock, remove all wheel nuts/bolts, and install the new wheel. Install the wheel lock in accordance with the McGard installation instructions.
