DIFFERENTIAL BUFFER - Febi - AB-NS-006

A differential buffer, also known as a jounce bumper or bump stop, is a rubber or polyurethane component installed on the vehicle's rear axle. Its main function is to cushion the impact when the suspension compresses to its limit, preventing direct metal-on-metal contact between the vehicle chassis and the differential housing. This protects the differential from damage and helps maintain a smoother ride.

Common signs of a worn or damaged differential buffer include harsh thumping or banging noises from the rear suspension when going over bumps, especially when carrying a load. Visually inspect the buffer for cracks, tears, crumbling, or if it appears to be completely missing or detached.

While it's possible for experienced DIY mechanics with proper tools and safety equipment, professional installation is highly recommended. The process involves safely lifting the vehicle, accessing the rear suspension, and ensuring correct alignment and torque specifications, which can be complex and dangerous if done improperly.

This Febi Differential Buffer (AB-NS-006) is compatible with specific Nissan models including PICK UP (D21), TERRANO II (R20), TERRANO I (WD21), NAVARA Pick-up (D21), and Pathfinder I (WD21). It is crucial to verify your vehicle's engine type (3.0 4WD, 2960cc) and manufacturing year (1986.07-1995.08) for exact compatibility.

No, this is not an OEM part. It is a high-quality OE replacement part manufactured by Febi, a reputable automotive parts supplier. It is designed to meet or exceed the specifications of the original equipment part it replaces (OE#55060-0F600, 550600F60A, and 5506041G00).

The lifespan of a differential buffer can vary greatly depending on driving conditions, vehicle load, and material quality. Under normal conditions, they can last many years. However, frequent driving on rough roads, carrying heavy loads, or exposure to harsh environmental elements can accelerate wear. Regular inspection helps determine when replacement is necessary.

Double-check the OE part numbers (55060-0F600, 550600F60A, 5506041G00) and your vehicle's specific make, model, engine type (3.0 4WD), and manufacturing year (1986.07-1995.08). Even slight variations can affect fitment. If discrepancies are found, return the part and acquire the correct one.

While the differential buffer addresses impacts, other suspension components can also cause noise. Inspect your vehicle's shock absorbers, leaf springs, spring bushings, and sway bar links for signs of wear, damage, or looseness. A professional mechanic can diagnose other potential issues.

Verify that the buffer was correctly installed and securely fastened. Ensure there are no external factors like fluid leaks (e.g., from shocks or differential) or extreme heat exposure causing premature deterioration. Also, confirm the buffer is not being over-compressed due to continuously overloaded vehicle conditions or other failing suspension components.

While a new buffer will absorb impacts, it won't correct issues with worn-out shocks or springs. Evaluate the condition of your shock absorbers and leaf springs; if they are failing, they can cause a stiff or uncontrolled ride. Ensure tire pressures are set to manufacturer specifications.
