Timken 25877 Transfer Case Output Shaft Bearing

Timken 25877 Transfer Case Output Shaft Bearing

Timken 25877 is a transfer case output shaft bearing built for applications that need controlled support under radial and axial load. With a 1.375 in. (34.93 mm) inside diameter, 0.969 in. (24.61 mm) cone width, and 0.059 in. (1.50 mm) cone radius, this tapered roller bearing is sized for compact driveline packaging and dependable shaft support.

Use this bearing when servicing rear, rear inner, or rear forward positions on select Jeep, Ford, Nissan, Chevrolet, Pontiac, Chrysler, Dodge, GMC, and Isuzu applications. Timken 25877 is also a direct reference point for transfer case and manual transmission service on vehicles such as Jeep CJ7, Ford Bronco, and Nissan 300ZX.

What It Helps Address

• Transfer case shaft noise from worn bearing surfaces
• Excessive shaft play in rear output or input shaft locations
• Vibration caused by bearing wear in driveline service
• Rough operation during transfer case or transmission rebuilds
• Loss of bearing support in high-load, high-mileage applications

Installation Notes and Tips

Inspect the mating cup/race during service and replace the inner cone and outer cup together to maintain bearing life and reliability. Confirm the exact position, spline count, and transfer case or transmission type before installation, especially on Jeep, Ford, and Nissan applications with multiple bearing variants. Clean and inspect the shaft, housing, and seal surfaces before assembly.

Quality Assurance

Timken is recognized globally for tapered roller bearing engineering. This bearing is built to manage both radial and axial loads while maintaining durability in a compact space, making it a practical choice for transfer case output shaft service and related driveline repairs.
