Lower Steering Shaft for 2015-2021 Tesla Model X | 1027826-00-A

Why This Shaft Defines Your Model X’s Steering Precision

What It Does (Beyond “Just a Metal Rod”)

• Direct Power Transmission: Connects the upper steering column to the steering rack, transferring rotational force from the wheel to the rack with zero loss. No “loose” feeling when turning—just immediate response.
• Vibration Dampening: Built with rubber isolators that absorb road vibrations, preventing them from traveling up to the steering wheel. Say goodbye to shaky hands on rough roads.
• Telescoping Flexibility: Works with your Model X’s adjustable steering column, allowing smooth height/tilt adjustments without binding or stress on the shaft.
• Safety Under Stress: Reinforced steel construction withstands sudden torque (like hitting a pothole or avoiding an obstacle), ensuring the steering system stays intact when you need it most.

Signs Your Lower Steering Shaft Needs Replacement

• Steering Play: The wheel moves 2-3 inches before the wheels respond. This “slop” is a classic sign of a loose or worn shaft.
• Clunking Noises: A “thud” or “click” when turning, especially at low speeds. Often caused by worn universal joints in the shaft.
• Vibration in the Wheel: Shaking or buzzing during acceleration or turns, indicating the shaft is no longer dampening road vibrations.
• Stiff Steering: The wheel feels harder to turn, especially at low speeds. A seized or binding shaft can restrict movement, risking loss of control.

Built to Tesla’s Rigorous Standards

Why It Outperforms Aftermarket Alternatives

• Tesla-Calibrated Fit: Precisely machined to match Model X’s steering column and rack, ensuring zero binding during adjustments.
• Sealed Universal Joints: Unlike aftermarket parts with exposed joints (prone to rust), these are 终身密封 (lifetime-sealed) to resist dirt, water, and corrosion.
• OEM-Grade Steel: Heat-treated to withstand the torque demands of Model X’s heavy-duty steering system, preventing bending or warping.
