As a critical load-bearing and vibration-isolating component for the rear drive system of 2012-2021 Tesla Model S/Model X, this premium brand-grade rear drive unit motor mount is engineered to match original factory specifications, with core functions focusing on "rear motor stabilization + multi-dimensional vibration control":
- Rear Motor Secure Fixation: It acts as a "bridge" between the rear drive unit motor and the vehicle chassis, adopting a 3-point reinforced mounting structure to lock the motor in its factory position. This prevents lateral displacement or vertical 窜动 of the motor during high-speed acceleration, regenerative braking, or rough road driving—avoiding damage to connected components such as rear drive shafts, power cables, and cooling pipelines.
- Multi-Frequency Vibration Damping: The mount integrates a dual-layer composite damping structure (high-elasticity EPDM rubber + metal buffer sheet) that targets the 12-400Hz vibration range of Tesla’s rear drive motor. It absorbs over 85% of low-frequency vibration (generated during steady-speed driving) and high-frequency impact (caused by sudden torque changes), significantly reducing rear-end hum and rattling transmitted to the cabin.
- Chassis Load Protection: With a "radial load dispersion" design, it evenly distributes the rear motor’s weight (about 100-120kg) to 4 key chassis load-bearing points. This avoids local stress concentration that could lead to chassis deformation or suspension misalignment, ensuring long-term stability of the vehicle’s rear-end handling.
Replace this rear drive unit motor mount immediately if you observe the following symptoms, which indicate component wear or failure:
- Rear Cabin Noise: A continuous "low-frequency hum" from the rear end during highway driving (80-120km/h) or "knocking" sounds when accelerating/braking suddenly—caused by worn damping rubber or detached buffer sheets.
- Visible Component Damage: The mount body is bent, cracked, or has broken mounting lugs; the damping rubber is split, bulging, or has fallen off the aluminum base—resulting in loss of motor support and vibration isolation functions.
- Rear Motor Misalignment: Uneven wear on the rear tires (e.g., faster wear on the outer edge), or a "wobble" feeling when the vehicle is driving straight—triggered by mount deformation that shifts the rear motor out of its original position.
- Loose Fixing Bolts: Bolts connecting the mount to the chassis or rear motor keep loosening (even after re-tightening), which is a sign of worn mounting holes or reduced structural stability of the mount.
- 1× Rear drive unit motor mount (1028034-00-B)
- 3× High-tensile fixing bolts (Tesla original-spec M10×1.5, pre-coated with anti-seize compound to prevent thread galling)
- 1× Torque specification card (recommended torque: 38±2Nm for chassis bolts, 43±2Nm for motor bolts—complies with Tesla service manual standards)
- 1× Silicone lubricant packet (for coating the damping rubber surface, reducing friction and extending rubber service life)
- Torque wrench (range: 0-100Nm, for precise bolt tightening)
- Socket set (12mm, 15mm—matches the size of fixing bolts)
- Hydraulic jack + heavy-duty jack stands (for lifting the vehicle’s rear end and supporting the rear drive motor)
- Wire brush + rust remover (for cleaning rust, oil, or debris from chassis and motor mounting points)
- Safety Preparation: Before disassembling the old mount, lift the vehicle’s rear end with a hydraulic jack and secure it with jack stands—never rely solely on the jack to avoid the rear motor dropping and causing injury.
- Disassembly Order: First remove the 2 bolts connecting the mount to the rear motor, then the 1 bolt connecting it to the chassis; avoid pulling the mount forcefully to prevent damage to nearby power cables or cooling pipelines.
- Cleaning Step: Use rust remover and a wire brush to thoroughly clean the mounting surfaces of the chassis and rear motor—ensure no rust or debris remains, as gaps can cause abnormal noise after installation.
- Torque Control: Use a calibrated torque wrench to tighten bolts to the recommended values; over-tightening may deform the mount body, while under-tightening leads to mount looseness and vibration.
- Warranty Service: Provides a 3-year/70,000-kilometer warranty (whichever comes first). During the warranty period, if the mount body bends/cracks (non-human damage) or the damping rubber 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., rear motor positioning, torque verification) and troubleshoot post-installation issues (e.g., abnormal rear-end noise).
- Compatibility Guarantee: If the mount is incompatible with your 2012-2021 Model S/Model X (confirmed via VIN check), 7-day no-reason return is supported (product must be uninstalled and packaging intact).
If you need to confirm compatibility with your specific Tesla model (e.g., 2020 Model X Long Range) or have questions about installation steps, please click "Contact Us" or send a message via the chat box—our team will respond promptly with professional, personalized support. For bulk purchase needs (e.g., repair shops, fleet maintenance), we also offer flexible, negotiable terms to meet your specific requirements.
