2. Product Features
- Simplified Installation: The cone-shaped design facilitates easier CV boot installation, reducing effort and potential damage.
- Durable Construction: Made from high-quality plastic material for repeated use and longevity.
- Universal Compatibility: Suitable for a wide range of stretchable CV boots.
- Compact Dimensions: Designed for practical handling and storage.
3. Safety Information
Always prioritize safety when working with automotive components. Adhere to the following guidelines:
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Ensure the vehicle is securely supported on jack stands before beginning any work.
- Keep hands and clothing clear of moving parts.
- Use the tool only for its intended purpose.
4. Setup and Preparation
Proper preparation is crucial for successful CV boot installation.
- Inspect CV Boot: Before using the cone, verify that your replacement CV boot is designed to stretch and can expand to a diameter larger than the base of the cone (110 mm / 4.33 inches). The boot must be elastic enough for the cone to function correctly.
- Clean the Tool: Ensure the CV boot installation cone is clean and free of debris.
- Apply Lubricant: Apply a generous amount of appropriate lubricant (e.g., silicone spray or grease) to the entire surface of the cone. This reduces friction and prevents damage to the CV boot during installation.

5. Operating Instructions
Follow these steps to install a CV boot using the HILAKE cone tool:
- Prepare the Axle: Remove the old CV boot and clean the CV joint and axle shaft thoroughly. Ensure there are no sharp edges or burrs that could damage the new boot.
- Position the Boot: Slide the small end of the new CV boot over the narrow end of the cone tool.
- Stretch the Boot: Carefully and gradually pull the CV boot over the cone, stretching it until it passes over the widest part of the cone. Apply consistent pressure and ensure the boot stretches evenly. The lubricant applied earlier will assist in this process.
- Slide onto Axle: Once the boot is fully stretched over the cone, slide the entire assembly (cone with boot) onto the axle shaft.
- Remove Cone: Once the boot is past the CV joint and in its correct position on the axle, carefully remove the cone tool.
- Secure the Boot: Install the new CV boot clamps to secure the boot to the CV joint and axle shaft.

6. Maintenance
To ensure the longevity and effectiveness of your HILAKE CV Boot Installation Cone Tool:
- After each use, clean the tool thoroughly to remove any lubricant, grease, or debris.
- Store the tool in a clean, dry place, away from direct sunlight and extreme temperatures.
- Inspect the tool periodically for any signs of damage or wear. Replace if cracks or significant deformation are observed.
7. Troubleshooting
If you encounter difficulties during installation:
- Boot Not Stretching: Ensure the CV boot is genuinely a 'stretch' type and that its material is sufficiently elastic. Some boots may require warming in hot water to increase flexibility before stretching.
- Excessive Friction: Re-apply lubricant generously to the cone surface and the inside of the CV boot. Using a suitable lubricant is critical for smooth operation.
- Tool Appears Too Large: Confirm the boot's maximum stretch diameter is greater than the cone's base diameter (110 mm / 4.33 inches). This tool is designed for universal stretch boots, but some specific boot designs or smaller applications may not be compatible.
