Left Front Drive Motor Mount Bracket for 2012-2020 Tesla Model X/Model S | 1055368-00-G

1. Core Function Description

1. Secure Motor Anchoring: It serves as a fixed interface between the left front drive motor and the vehicle chassis, using a 4-point positioning structure to lock the motor in place. This prevents lateral shifting or vertical movement of the motor during acceleration, deceleration, or sharp turns—avoiding damage to connected parts like drive shafts, wiring harnesses, and coolant hoses.
2. Vibration Damping & Noise Reduction: The bracket integrates a high-density nitrile rubber damping pad (optimized for Tesla’s drive motor vibration frequency) that absorbs 80% of the 15-350Hz vibrations generated during motor operation. This minimizes low-frequency hum in the cabin (common during highway driving) and high-frequency rattling (when the motor starts or stops), restoring a quiet driving experience.
3. Load Distribution & Chassis Protection: Adopting a "honeycomb-like stress dispersion" design, it evenly distributes the motor’s weight (about 90-110kg) to multiple load-bearing points on the chassis. This prevents local stress concentration from causing chassis deformation, ensuring long-term stability of the front suspension system.

3. Fault Judgment (Signs for Replacement)

• Front Chassis Noise: A continuous "squeaking" or "thudding" sound from the left front during driving (especially when accelerating sharply or going over speed bumps)—caused by worn rubber damping pads or loose bracket connections.
• Visible Component Damage: The bracket body is bent, cracked, or has broken mounting lugs; the rubber damping pad is split, bulging, or detached from the steel bracket—leading to loss of motor support and vibration isolation functions.
• Motor Misalignment: Uneven wear on the left front tire (e.g., faster wear on the inner edge), or a "pulling" feeling when steering straight—resulting from bracket deformation that shifts the drive motor out of its original position.
• Loose Fixing Bolts: Bolts connecting the bracket to the chassis or motor keep loosening (even after re-tightening), which is a sign of worn mounting holes or reduced structural stability of the bracket.

5. Installation Details

5.1 Package Contents

• 1× Left front drive motor mount bracket (1055368-00-G)
• 4× High-tensile fixing bolts (Tesla original-spec M12×1.75, pre-coated with anti-seize compound to prevent thread jamming)
• 1× Torque specification card (recommended torque: 42±2Nm for chassis bolts, 48±2Nm for motor bolts—complies with Tesla service manual standards)
• 1× Anti-corrosion grease packet (for coating mounting points, enhancing rust resistance)

5.2 Installation Tools Required

• Torque wrench (range: 0-150Nm, for precise bolt tightening)
• Socket set (14mm, 17mm—matches bolt sizes)
• Hydraulic jack + heavy-duty jack stands (for lifting the front chassis and supporting the drive motor)
• Wire brush + degreaser (for cleaning rust, oil, or debris from mounting surfaces)

5.3 Installation Precautions

1. Safety First: Before disassembling the old bracket, lift the vehicle’s front left side with a hydraulic jack and secure it with jack stands—never rely solely on the jack to avoid motor dropping.
2. Disassembly Order: First remove the 2 bolts connecting the bracket to the motor, then the 2 bolts connecting it to the chassis; avoid pulling the bracket forcefully to prevent damage to nearby coolant lines or wiring.
3. Cleaning Step: Use degreaser and a wire brush to thoroughly clean the motor and chassis mounting surfaces—ensure no debris remains, as gaps can cause abnormal noise after installation.
4. Torque Control: Use a calibrated torque wrench to tighten bolts to the recommended values; over-tightening may deform the bracket, while under-tightening leads to looseness and vibration.

6. After-Sales Support

• Warranty Service: Provides a 4-year/80,000-kilometer warranty (whichever comes first). During the warranty period, if the bracket bends/cracks (non-human damage) or the rubber pad fails prematurely, a free replacement will be provided.
• Technical Assistance: Dedicated EV technicians are available via email or online chat to answer installation questions (e.g., motor positioning, torque verification) and troubleshoot post-installation issues (e.g., abnormal noise).
• Compatibility Guarantee: If the bracket is incompatible with your 2012-2020 Model X/Model S (confirmed via VIN check), 7-day no-reason return is supported (product must be uninstalled and packaging intact).
