Operating Instructions
This tool is designed to facilitate the safe removal and installation of center lock wheels, specifically preventing contact and potential damage to carbon ceramic brake discs.
Wheel Removal Procedure (Using the Tool as a Guide)
- With the vehicle securely lifted and the wheel ready for removal, carefully unthread the center lock nut.
- Once the center lock nut is removed, the wheel may still be seated tightly on the hub.
- Insert the ZKTOOL Center Lock Wheel Alignment Tool into the center of the hub, threading it into the existing center lock mechanism. This tool acts as a guide pin.
- Gently pull the wheel outwards, guiding it along the alignment tool. The tool ensures the wheel slides off straight, preventing it from tilting and potentially contacting the brake disc.
- Once the wheel is clear of the hub, remove the alignment tool.

- Carefully align the wheel onto the alignment tool. The tool will guide the wheel precisely onto the hub, ensuring proper seating and preventing accidental contact with the brake disc, especially crucial for carbon ceramic rotors.
- Slide the wheel fully onto the hub along the guide tool.
- Once the wheel is seated, remove the ZKTOOL alignment tool.
- Install and torque the center lock nut according to the vehicle manufacturer's specifications.
