• Position on Vehicle: Rear axle, track rod arm / control-link connecting the axle carrier to the body or sub-frame, controlling lateral and longitudinal motion of the rear axle.

• Cross-Reference / Alternative Numbers: OE reference 981 331 045 03, replaces number 981 331 045 02

• Applications: Suitable for replacement when the original link shows wear, has failed bushings/joints, produces rear suspension noise, causes misalignment or uneven tyre wear, or is being renewed as part of a rear suspension service.

The rear track rod arm is a key component in maintaining the correct geometry of the rear axle - the lateral control, alignment setting and load path all rely on it performing correctly. A failing or worn link can result in:
• Unstable rear-end behaviour under cornering or load
• Premature or uneven tyre wear especially on the rear axle
• Noise or clunks from suspension movement under load
• Inability to hold alignment settings or poor road feel

Replacing the component ensures your rear suspension remains factory-accurate, the tyres wear evenly, handling remains sharp and the car instils confidence.

When and why to replace:
• You hear clunking or knocking from the rear suspension when driving over bumps or changing direction
• Rear tyre wear is uneven or alignment cannot be maintained
• The original link shows play in the bushings or joints or is visibly corroded or bent
• During a rear suspension overhaul, axle servicing or after accident damage
• On higher-mileage vehicles where original suspension links have undergone significant service life.
