5. Setup and Installation
Installation of the CNC Metal Front Steering Hub Set requires basic RC assembly skills and tools. Always refer to your 3Racing Sakura D4 vehicle's original instruction manual for specific disassembly and reassembly procedures related to the front suspension and steering components.
General Installation Steps:
- Preparation: Ensure your RC vehicle is powered off and the battery is disconnected. Gather necessary tools (e.g., small screwdrivers, hex wrenches, pliers).
- Disassembly: Carefully remove the existing front steering hubs from your Sakura D4. Pay attention to the order and orientation of all screws, pins, and shims.
- Bearing Transfer: The Hobbypower hubs come with bearings pre-installed. If you need to transfer any additional components (e.g., axle pins, hex adapters) from your old hubs, do so now.
- Installation: Mount the new Hobbypower CNC Metal Front Steering Hubs onto the suspension arms and steering linkages. Ensure all connections are secure but do not overtighten screws, as this can strip threads or damage components.
- Check Movement: After installation, manually check the steering movement to ensure it is smooth and free of binding. The wheels should turn freely without obstruction.
- Final Inspection: Double-check all fasteners and connections before operating the vehicle.

6. Operating Considerations
Once installed, the CNC Metal Front Steering Hubs are designed to provide a more robust and precise steering experience. No special operating procedures are required beyond normal RC vehicle operation. However, always be mindful of your driving environment and avoid excessive impacts that could damage any RC components.
7. Maintenance
Regular maintenance will extend the lifespan and performance of your CNC Metal Front Steering Hubs.
Maintenance Tips:
- Cleaning: After each use, especially in dusty or dirty conditions, clean the hubs and surrounding areas with a soft brush or compressed air to remove debris.
- Inspection: Periodically inspect the hubs for any signs of wear, bending, or damage. Check that all screws remain tight.
- Bearing Care: The included bearings are sealed, but if exposed to excessive dirt or moisture, they may require cleaning and re-lubrication or replacement. Consult an RC hobby expert if unsure.
- Lubrication: No regular lubrication is needed for the aluminum hub itself, but ensure any moving parts connected to it (e.g., steering linkages, suspension pins) are properly lubricated according to your vehicle's manual.

8. Troubleshooting
While the CNC Metal Front Steering Hubs are designed for reliability, here are some common issues and their potential solutions:
Common Issues:
- Loose Steering:
Possible Cause: Loose screws on the hubs or steering linkages.
Solution: Inspect and tighten all screws. Ensure no play in the ball ends or pivot points. - Binding/Stiff Steering:
Possible Cause: Overtightened screws, debris in bearings, or misaligned components.
Solution: Loosen screws slightly and re-tighten. Clean bearings. Check for any parts rubbing or misaligned. - Unusual Noise from Hub Area:
Possible Cause: Damaged or worn bearings, or debris.
Solution: Inspect bearings for smooth rotation. Clean or replace if necessary. - Hubs Bending/Breaking:
Possible Cause: Severe impact or manufacturing defect.
