NISSAN 40242-VB000 Front Grease Catcher Plate

The genuine NISSAN 40242-VB000 (Front Grease Catcher Plate / CATCHER, GREASE FRONT) is a premium-quality, original equipment manufacturer part that plays a crucial role in ensuring proper lubrication of the front wheel hub and bearings, as well as protecting the braking system.

Key Functions and Operating Principle:

The front grease catcher plate is positioned directly at the front wheel hub assembly. Its primary purpose is to retain the grease required for wheel bearing lubrication in the appropriate location, preventing it from leaking out. Additionally, it forms a physical barrier that shields the brake discs and brake pads from escaping lubricant, which would otherwise drastically reduce braking efficiency. It also protects the bearings from external contamination, such as dust, mud, water, and road salt.

Technical Specifications:

• Manufacturer: NISSAN (Original Equipment Manufacturer - OEM)
• Part Number: 40242-VB000
• Part Type: Front Grease Catcher Plate (Catcher, Grease Front)
• Fitting Position: Front axle (left/right side at the wheel hub)
• Material: Durable pressed steel with a corrosion-resistant coating, resistant to high temperatures and mechanical stress.

Signs of Failure or Wear:

Because this part is continuously exposed to environmental conditions, it can wear out over time. Common symptoms and issues include:

• Severe corrosion: Moisture and road salt can cause the plate to rust through, compromising its sealing and protective functions.
• Mechanical damage: During wheel bearing replacement or suspension service, the plate can easily become deformed, resulting in rubbing noises or improper alignment.
• Grease leakage: If the plate is damaged or aged, grease escaping from the wheel hub bearing can spread to the wheel rim or brake components, creating a serious safety hazard.

To maintain the safe operation of the suspension and braking systems, a damaged or corroded grease catcher plate must be replaced promptly. Genuine NISSAN OEM components ensure a precise fit and long service life.
