Rear Left Stabilizer Link Assembly

Rear Stabilizer Link — Left Hand

(Tesla PN: 1044491-00-F)

Replacement Tesla Model 3 / Model Y rear stabilizer link assembly (left hand),
also known as the rear sway bar link or anti-roll bar link. This link connects the rear stabilizer bar to the suspension arm/knuckle, transferring roll forces between the left and right sides of the rear axle. Worn stabilizer links are a common source of rear-end clunks, knocks, and play during low-speed maneuvers and over bumps. This left-hand link is a direct-fit replacement for Tesla part number 1044491-00-F on most Model 3 and Model Y variants.

Built using Delphi OE safety technology, this stabilizer link is engineered and tested to OE-level standards:
Validated from below −40 °C to over 120 °C, subjected to up to 720 hours of salt spray, and checked with extensive dimensional and material analysis to ensure excellent compatibility with the original Tesla part. Delphi’s sway bar links are fatigue tested and feature ultrasonic molding to help prevent weld breakage and provide long-term durability.

• Anti-corrosion protection — Coated components for optimum corrosion resistance and clean appearance.
• Micron-level machining — Tight tolerances help ensure smooth joint operation and long service life.
• Fatigue-tested design — Validated to resist cracking and failure under repeated load.
• Ultrasonic-molded joints — Advanced manufacturing to help prevent weld breakage over time.

Why this part needs replacement

• Clunking from the rear — Worn or loose ball joints at either end of the link can cause sharp clunks or rattles from the rear suspension area when driving over rough roads, speed bumps, or driveway transitions.
• Play in the rear stabilizer bar — Excess clearance in the joints allows the sway bar to move independently of the suspension, reducing roll control and creating vague handling from the rear of the car.
• Contamination & wear — Once joint sealing is compromised, water, dirt, and road salt accelerate internal wear and can eventually lead to link failure.
• Noise during weight transfer — A worn rear stabilizer link may cause knocking or clicking noises when transitioning weight side-to-side or when entering/exiting driveways at an angle.
• Post-impact or suspension repair — After curb strikes, pothole impacts, or rear suspension work, stabilizer links are often replaced to restore factory ride and handling.

What this assembly does for your Model 3 / Model Y

• Controls rear body roll — Couples the rear suspension to the stabilizer bar so the car stays flatter and more composed during cornering.
• Improves stability and confidence — Reduces slop and delay between rear-axle response and chassis movement, helping the car feel more planted.
• Eliminates rear-end rattles — Fresh joints help quiet common clunks, rattles, and knocks from the rear sway bar area when driving over small bumps.
• Maintains consistent handling left-to-right — Ensures that both rear wheels share roll load correctly, preserving predictable, neutral handling.
• Direct bolt-in replacement — Designed to fit the OEM mounting points and geometry for vehicles equipped with Tesla PN 1044491-00-F on the left-hand side.
