Rear Left Hand Mount Assembly for Tesla Model X/S/Y/3 | 1095337-00-D

1. Key Specifications & Compatibility

2. Why This Brand-Grade Rear Left Mount Assembly Is Critical for Your Tesla

1. Secures the Rear Powertrain: The high-strength aluminum bracket anchors the rear drive unit (or battery support frame) to the chassis, preventing lateral or vertical movement during acceleration, braking, or cornering. A weak bracket causes powertrain shifting, which strains drive shafts, damages wiring harnesses, or leaks fluids from misaligned hoses.
2. Blocks Powertrain Vibration: The EPDM rubber bushing acts as a “shock absorber” for powertrain vibration—reducing low-frequency hum (common during highway driving) and high-frequency rattling (from drive unit operation) from transferring to the cabin. Generic mounts use low-density rubber that hardens over time, losing vibration control and increasing cabin noise.
3. Resists Corrosion & Wear: The anodized bracket and UV-resistant bushing withstand harsh under-vehicle conditions (e.g., road salt in winter, rain in summer, UV exposure in hot climates). Generic mounts often use uncoated steel brackets (rust quickly) or cheap rubber (cracks in 1–2 years), requiring frequent replacement.
4. Maintains Factory Alignment: The 3-point factory-matched mounting holes ensure the powertrain stays in its original position, preserving drive efficiency and preventing uneven tire wear (caused by misaligned powertrains). Ill-fitting generic mounts force the powertrain out of alignment, leading to poor handling and increased tire replacement frequency.

3. What It Actually Does (No Tech Jargon)

• Holds the Rear Drive Unit Secure: This assembly acts like a “strong, flexible anchor” on the left side of the rear powertrain—it keeps heavy parts (like the rear drive unit) firmly attached to the chassis, so they don’t shift when you speed up, slow down, or take sharp turns.
• Makes Rides Quieter: The rubber bushing in the assembly soaks up vibration from the rear powertrain—you won’t hear loud humming on the highway or rattling when the drive unit is working, making long drives much more comfortable.
• Won’t Rust or Fall Apart: The aluminum bracket is coated to resist rust (even in snowy, salty weather), and the rubber bushing won’t crack or harden in the sun. Unlike cheap mounts that need replacing every year, this one lasts for years.
• Fits Like It Came from the Factory: It has the exact same mounting holes as your Tesla’s original part—you can bolt it on directly without drilling new holes or modifying the chassis. No guesswork, no risk of damaging your car.

4. Signs You Need to Replace This Mount Assembly

• Excessive Cabin Noise: Loud low-frequency hum from the rear of the vehicle (especially during acceleration) or high-frequency rattling when the drive unit is active—signals the rubber bushing has hardened or cracked, losing vibration-damping ability.
• Visible Damage: The bracket is bent, cracked, or has broken mounting tabs; the rubber bushing is split, bulging, or detached from the bracket—can’t secure the powertrain or absorb vibration.
• Powertrain Misalignment: Uneven tire wear (rear tires wearing faster on one side), difficulty steering at high speeds, or unusual noise from the rear drive shaft—indicates the mount has failed, shifting the powertrain out of factory position.
• Loose Mounting Bolts: Bolts securing the assembly to the chassis or powertrain keep coming loose (signals the bracket’s mounting holes are worn, or the bushing is deflecting excessively—requiring full assembly replacement).
• Vibration in the Steering Wheel/Seats: Vibrations from the rear powertrain transfer to the steering wheel or front seats (unusual for Teslas)—a clear sign the rear mount is no longer isolating vibration.

5. Why This Brand-Grade Assembly Outperforms Generic Alternatives

• Tesla-Spec Strength & Damping: Generic mounts use low-grade steel brackets (tensile strength <250 MPa) that bend under load, or soft rubber bushings (shore hardness <50A) that deflect too much. This assembly uses 320 MPa aluminum and 65A EPDM rubber—matching factory performance for strength and vibration control.
• Integrated Factory Design: Generic mounts often separate the bracket and bushing (requiring separate purchase and alignment), leading to fitment issues. This assembly is pre-assembled (bracket + bushing) to factory tolerances—no alignment guesswork, direct bolt-on installation.
• Durable Coatings & Compounds: Generic brackets use thin paint that peels off in 6–12 months; their bushings use non-UV-resistant rubber that cracks in sunlight. This assembly’s anodized coating and UV-resistant rubber last 6+ years, avoiding premature replacement.
• Perfect Fitment: Generic mounts have mismatched mounting holes (forcing users to drill the chassis—risking damage). This assembly’s 3-point alignment matches Tesla’s rear chassis exactly, no modifications needed.

6. Installation & What You Receive

• 1x Rear Left Hand Mount Assembly (1095337-00-D)
• 3x High-tensile mounting bolts (factory-spec thread size; pre-coated with anti-corrosion compound—avoids rusting in mounting holes)
• 1x Bolt torque specification card (lists Tesla’s official torque values for each mounting point—critical for safe installation)
• Digital Installation Guide: Step-by-step instructions with photos, including:
  1. Safety Prep: Secure the rear powertrain with a hydraulic support jack (to avoid dropping when the old mount is removed; use jack stands for additional safety).
  2. Removal Steps: Disconnect the old assembly’s mounting bolts (start with chassis bolts, then powertrain bolts), detach the worn mount, and clean mounting surfaces of debris/rust.
  3. Installation Steps: Align the new assembly with factory mounting points, hand-tighten all bolts, then torque to Tesla’s recommended values (refer to included card—over-tightening damages the bushing; under-tightening causes looseness).

7. After-Sales Support
