• Timken engineering support and bearing manufacturing expertise
• Direct replacement part number: JLM104948

Detailed Description

Timken JLM104948 is a transfer case output shaft bearing used in driveline assemblies that require precise shaft support and consistent rotation. The tapered roller design helps manage side load and thrust load together, which is important in transfer case and axle service where alignment and load control affect bearing life. This bearing is listed for applications such as 2011-2017 Chevrolet Caprice rear, 2014-2017 Chevrolet SS rear, 1999-2005 Ford F-250 Super Duty front, 1997-2003 BMW 540i rear, and 1975-1997 Toyota Land Cruiser front inner and rear inner positions.

Common Problems This Part Can Help Address

• Noise from a worn transfer case or driveline bearing
• Excess shaft play in the output shaft assembly
• Rough rotation caused by bearing wear or fatigue
• Vibration related to degraded bearing surfaces
• Reduced service life from a mismatched or worn bearing component

Installation Notes and Tips

Inspect the mating cone and cup before installation. Timken recommends replacing both the inner cone and outer cup at the same time to help maximize reliability and service life. Verify the vehicle application, axle configuration, and position before ordering, especially on Ford Dana/Spicer 50 Series and Toyota full-floating axle applications.

Quality Assurance

Timken is recognized for tapered roller bearing engineering and application support. JLM104948 is manufactured to support demanding driveline service where load capacity and bearing consistency are important.
