Detailed Description

Timken M86647 is a transfer case output shaft bearing designed for driveline applications where load control and long service life matter. Timken’s tapered roller bearing design is used to manage combined loads while maintaining stable operation in demanding transfer case and axle locations. This part number is used across a wide range of vehicles, including 1984-1996 Chevrolet Corvette rear outer applications, 1987-1991 Ford Tempo front output shaft applications, and multiple Volvo rear outer applications such as the 1997-1998 Volvo S90 and V90, 1992-1997 Volvo 960, and 1991-1995 Volvo 940.

What It Helps Fix

• Excessive bearing noise from the transfer case output shaft area
• Rough or loose driveline operation caused by worn bearing surfaces
• Endplay or load instability in the output shaft assembly
• Service issues in rear outer, front, or front outer bearing positions
• Wear-related driveline vibration in supported applications
