Toyota Hilux Surf 215 Cushion Sub-Assy Cab Mounting NO.2 Upper FE

The Cushion Sub-Assy Cab Mounting, often simply referred to as the cab mount or cab mounting cushion, is a component of a vehicle’s chassis or frame system. Its primary function is to provide a cushioned connection between the vehicle’s cab or passenger compartment and the frame or chassis.

Components and Design:

• Rubber or Polyurethane Material: The cab mount is typically made of rubber or polyurethane material that absorbs vibrations and shocks, providing a smoother and more comfortable ride for occupants.
• Metal Inserts or Reinforcements: Some cab mounts may have metal inserts or reinforcements to provide additional strength and durability, helping to maintain the structural integrity of the vehicle’s chassis.
• Mounting Bolts or Fasteners: The cab mount is attached to the vehicle’s cab and frame/chassis using mounting bolts or fasteners, securing it in place while allowing for some degree of flexibility and movement.

Benefits;

1. Vibration Damping:

• Reduced Vibrations: The cushion sub-assembly absorbs and dampens vibrations generated by the engine, drivetrain, and road surface, resulting in a smoother and more comfortable ride for occupants.

2. Noise Reduction:

• Quieter Cabin: By isolating the cab or body structure from chassis vibrations and road noise, the cushion sub-assembly helps reduce noise levels inside the vehicle, providing a quieter and more enjoyable driving experience.

3. Enhanced Comfort:

• Improved Ride Quality: A properly functioning cushion sub-assembly contributes to improved ride quality by minimizing harshness and impacts transmitted from the road surface to the vehicle occupants, leading to greater comfort on long journeys.

4. Structural Integrity:

• Maintains Structural Integrity: The cushion sub-assembly helps support and stabilize the cab or body structure, preventing excessive flexing or distortion, which could lead to premature wear or damage to other vehicle components.

5. Longevity and Durability:

• Extended Component Life: By reducing the transmission of vibrations and shock loads, the cushion sub-assembly helps prolong the lifespan of various vehicle components, including the cab or body structure, suspension components, and drivetrain.

6. Improved Handling and Stability:

• Enhanced Stability: A well-maintained cushion sub-assembly contributes to improved handling and stability by minimizing body roll, sway, and lateral movement, especially during cornering or evasive maneuvers.

7. Protection Against Corrosion:

• Prevents Corrosion: The cushion sub-assembly helps prevent metal-to-metal contact and corrosion between the cab or body structure and the chassis, particularly in areas prone to moisture and road salt exposure.

Signs a car needs a new one;

1. Excessive Noise and Vibration:

• Increased Noise: Worn or damaged cushion sub-assembly cab mounts can cause increased noise and vibration inside the vehicle’s cabin, especially during acceleration, deceleration, or when driving over bumps or rough roads.
• Excessive Vibration: A noticeable increase in vibrations felt in the vehicle’s cabin, particularly at certain speeds or under load, may indicate deteriorating cab mounts.

2. Loose or Unstable Cabin:

• Cabin Movement: A failing cushion sub-assembly cab mount may result in increased play or movement in the cabin structure, leading to a loose or unstable feeling, especially during cornering or sudden maneuvers.
• Unusual Handling: Handling characteristics may become compromised, with the vehicle feeling less stable and more prone to body roll or sway.

3. Uneven Tire Wear:

• Uneven Tire Wear: Worn cushion sub-assembly cab mounts can lead to uneven weight distribution and suspension alignment, causing irregular tire wear patterns. Inspect the tires for signs of abnormal wear, such as cupping or scalloping.

4. Fluid Leaks:

• Leaking Fluids: Inspect the cab mounts for signs of fluid leaks, which may indicate a failing cushion sub-assembly cab mount. Leaks can occur due to increased movement and stress on the cab structure caused by worn mounts.

5. Visual Inspection:

• Visible Damage or Wear: Inspect the cushion sub-assembly cab mounts visually for signs of damage, such as cracking, tearing, or deterioration. Pay close attention to the condition of the rubber or polyurethane material surrounding the mounts.
• Shifted or Misaligned Mounts: Misalignment or shifting of the cab mounts may indicate wear or failure, requiring replacement to restore proper alignment and function.

6. Suspension Sag or Sagging Ride Height:

• Uneven Ride Height: A noticeable sagging or uneven ride height in the cabin area, especially on one side, may indicate a problem with the cushion sub-assembly cab mounts. This occurs as the mounts lose their ability to support the weight of the cabin structure.
