Front Shock Absorber Mount Bushing/Rubber for 2017–2023 Tesla Model 3 / Model Y | SZ460C3301 (CFN Brand)

Core Functions

1. Vibration & Noise Isolation
   Made of high-elastic rubber, it absorbs high-frequency vibrations generated by the front shock absorber during driving (e.g., over potholes, gravel roads, or speed bumps). It blocks the transfer of mechanical noise from the shock absorber to the cabin, avoiding “rattling” or “hum” sounds in the front end and preserving the Model 3/Y’s quiet ride quality.
2. Shock Absorber Positioning
   Maintains the front shock absorber in its factory-calibrated vertical position, preventing lateral displacement caused by road impacts or steering forces. This ensures the shock absorber’s damping performance is fully exerted (e.g., stable rebound and compression), avoiding uneven tire wear or loose steering feel due to misaligned shock absorbers.
3. Impact Buffering
   Softens the direct impact between the shock absorber and strut tower during sudden loads (e.g., emergency braking, hitting curbs). It reduces mechanical stress on both the shock absorber top mount and body strut tower, extending the service life of these components and preventing premature fatigue damage.

Durable Construction

• Rubber Material: Uses OEM-grade chloroprene rubber (CR) with excellent elasticity (compression set ≤10% after 72 hours at 100°C) and anti-aging properties. It resists cracking, hardening, or degluing even under long-term exposure to engine heat, rain, or road salt.
• Structural Stability: Embedded with a metal inner sleeve (galvanized carbon steel, tensile strength ≥350MPa) for bolt installation. The sleeve ensures the bushing doesn’t deform under torque loads, while the galvanized coating prevents rust from underbody moisture.
• Environmental Adaptability: Withstands extreme temperatures (-40°C to 120°C) — remains flexible in cold winters (no brittle cracking) and stable in hot summers (no softening). It also resists corrosion from car wash chemicals or road de-icing salt.

Installation 要点

1. Vehicle Preparation: Lift the front end with jack stands, remove the front wheel, and gently peel back the fender liner to expose the front shock absorber top mount (under the hood’s front strut tower).
2. Old Bushing Removal: Use a 13mm socket to remove the 3 bolts securing the shock absorber top mount; take out the old bushing (note its orientation). Clean the mount’s surface to wipe away dust or residual rubber.
3. New Bushing Installation: Align SZ460C3301 with the top mount’s grooves, press it into place (ensure no tilting), then hand-tighten the 3 bolts to avoid cross-threading.
4. Torque Fastening: Use a torque wrench to tighten the bolts to 22±2 Nm (per Tesla’s specs) — over-tightening may compress the rubber excessively, reducing damping performance.
5. Post-Installation Check: Reinstall the wheel and fender liner, lower the vehicle, and road-test for abnormal front-end noise. If steering feels “stiff,” recheck the bushing’s alignment.

Note: For consistent performance, replace left and right bushings in pairs. Avoid using petroleum-based lubricants (they damage CR rubber); use OEM-spec rubber lubricant if needed.
