Core Features
Active Damping Technology: Unlike conventional hinges, this active hinge features a built-in damping system that controls the speed of the hood during opening and closing. It prevents sudden drops or slams, reducing the risk of damage to the hood or surrounding components and enhancing user safety.
OEM-Grade Precision Fit: Manufactured to the exact dimensions and tolerances of the 2021 Model 3's original hood hinge. This ensures a seamless installation without the need for modifications, maintaining the vehicle's factory-perfect alignment and structural integrity.
Lightweight yet Durable: Constructed from high-strength aluminum alloy, the hinge offers an optimal strength-to-weight ratio. It is both lightweight to minimize added weight to the vehicle and highly resistant to bending, warping, and wear, even with frequent use.
Corrosion Resistance: The anti-corrosion treatment and anodized coating protect the hinge from rust, salt, and moisture, ensuring long-term performance in various environments, from coastal areas with high humidity to regions with harsh winters.
Smooth and Quiet Operation: The precision-engineered components and damping mechanism work together to ensure the hood opens and closes with minimal friction and noise, preserving the Model 3's premium driving experience.
Installation Guidelines
Installing the HOOD HINGE, ACTIVE, LEFT HAND 1643845-00-A requires moderate mechanical skills. Follow these steps for a secure and proper installation:
Vehicle Preparation: Park the vehicle on a flat, level surface and engage the parking brake. Ensure the hood is fully open and properly supported using a hood prop to prevent accidental closing during installation.
Removing the Old Hinge:
Locate the bolts securing the old left-hand hood hinge to the hood and the vehicle's frame (typically 3-4 bolts on each end).
Use a torque wrench to carefully loosen and remove these bolts. Keep track of the bolts as they are specific to the hinge installation.
With the help of an assistant to support the hood, gently detach the old hinge from the hood and the frame.
Installing the New Hinge:
Align the new active hinge with the mounting holes on the hood and the vehicle's frame. Ensure the hinge is oriented correctly as per the original installation.
Hand-tighten the bolts to secure the hinge to both the hood and the frame, ensuring proper alignment.
Adjustment and Torque Tightening:
Check the alignment of the hood by closing it partially (do not fully close yet) to ensure it sits flush with the vehicle's body and there are no gaps or misalignments.
If adjustments are needed, slightly loosen the bolts, adjust the hinge position, and retighten.
Once aligned, use a torque wrench to tighten the bolts to the specifications outlined in the 2021 Tesla Model 3 service manual (typically 18-22 Nm).
Testing the Hinge: Open and close the hood several times to test the active damping functionality. Ensure the hood operates smoothly, without any unusual noises or resistance.
