NISSAN 40242-VC200 Grease Catcher Plate

This genuine Nissan (OEM: 40242-VC200) grease catcher plate (CATCHER-GREASE) is a precision-engineered protective component that plays a vital role in the reliable operation of the vehicle's suspension and braking systems. The primary function of this part is to retain lubricant within the wheel hub bearings and axle joints, as well as to protect braking surfaces from contamination.

Key Functions and Operating Principle

The grease catcher forms an effective physical barrier between rotating and stationary components. It prevents lubricating grease—which thins at high operating temperatures—from escaping the bearing housing and splashing onto the brake discs or brake pads, an occurrence that would cause a severe reduction in braking efficiency. At the same time, it shields the bearing and seals against external environmental hazards such as dust, mud, water, and road salt.

Technical Specifications

• Material: Premium-grade cold-stamped steel plate resistant to mechanical impacts and vibration.
• Surface Protection: Specialized corrosion-resistant coating for extended service life and oxidation protection.
• Factory Quality: Genuine Nissan OEM component ensuring exact dimensional tolerances and a perfect fit to the original stub axle.

Common Symptoms of Wear and Failure

Although the grease catcher is not a typical wear-and-tear item, it may require replacement due to the following factors:

• Corrosion: Road salt and moisture can thin or rust through the sheet metal, compromising its protective barrier.
• Mechanical Damage: Stone impacts, road hazards, or improper servicing procedures can deform the plate.
• Rubbing Noises: If a deformed plate contacts the rotating brake disc or wheel hub, it can generate a metallic squealing or rubbing noise.
• Grease Stains: Visible grease on the inner side of the wheel rim or around brake components, indicating lost sealing effectiveness.
