Rear Suspension Knuckle - Left for Tesla Model S (2016-2021) | 1042506-00-B

The Foundation of Rear-End Stability – OEM-Grade Strength for Precision Handling

Why This Knuckle Matters for Your Model S

The rear suspension knuckle is the critical link between your Model S’s wheels and suspension system, bearing the full force of road impacts, cornering, and braking. The 1042506-00-B is engineered to Tesla’s exact specifications, ensuring your 2016-2021 Model S maintains its signature smooth ride and responsive handling.

  • Model-Specific Fit: Exclusively designed for left rear suspension of Model S (2016–2021), with geometry tailored to match the vehicle’s rear track width (66.9 inches) and suspension travel (5.3 inches).
  • Load-Bearing Core: Supports up to 1,800 lbs of static load (per side) – critical for Model S’s battery-heavy rear end – while withstanding dynamic forces during hard acceleration or sudden stops.

Core Functions: Beyond “Just a Metal Bracket”

This knuckle is the backbone of rear suspension performance, responsible for:

  • Precise Wheel Alignment: Maintains camber (-1.5° ±0.5°) and toe (0° ±0.1°) settings, ensuring even tire wear and stable straight-line tracking.
  • Force Distribution: Channels lateral forces (from cornering) and longitudinal forces (from braking) to the suspension links, reducing stress on bushings and ball joints.
  • Hub Integration: Houses the rear wheel hub and bearing, providing a rigid mounting point for consistent rotation at speeds up to 155 mph (Model S Plaid).

Signs It’s Time to Replace Your Rear Knuckle

Don’t wait for a critical failure – watch for these warnings:

  • Uneven Tire Wear: Excessive inner/outer shoulder wear on rear left tire (indicates camber misalignment due to knuckle deformation).
  • Vibration at Speed: Shaking in the rear end above 60 mph, often caused by a bent knuckle throwing off wheel balance.
  • Clunking Noises: Metallic “clunks” when hitting bumps (signals worn mounting points or cracks in the knuckle).
  • Alignment Failures: Inability to maintain proper camber/toe despite repeated adjustments (a sure sign of structural damage).

Engineering That Matches Tesla’s Rigor

  • Material: Forged from SAE 1045 high-strength steel (tensile strength: 850 MPa), heat-treated to resist bending under extreme loads – 30% stronger than cast aluminum alternatives.
  • Precision Machining: CNC-machined mounting holes and hub bore (tolerance: ±0.02mm) ensure perfect alignment with suspension links and wheel hub.
  • Corrosion Resistance: E-coated with a 7-layer protective finish, tested to withstand 1,000 hours of salt spray (equivalent to 10+ years in harsh winter climates).

Professional Installation Guidelines

Due to safety-critical alignment requirements, professional installation is recommended:

  1. Pre-Installation Prep: Disconnect the 12V battery, remove rear left wheel, brake caliper, and rotor.
  2. Removal Steps:
    • Detach stabilizer bar link, upper/lower control arms, and trailing arm from the knuckle.
    • Extract the hub bearing assembly (use a press tool to avoid damaging the new knuckle).
  3. Installation:
    • Press in a new hub bearing (recommended: 1043284-00-A) and torque mounting bolts to 85 Nm.
    • Reattach suspension links with torque specs: control arms (120 Nm), trailing arm (150 Nm).
  4. Post-Installation: Perform 4-wheel alignment to reset camber/toe, and test drive to verify no vibrations.
