Timken LM102949 Tapered Roller Bearing Cone

Product Description

The TIMKEN LM102949 is a tapered roller bearing cone designed to handle both radial and axial loads in demanding drivetrain applications. This component is the inner race assembly of a tapered roller bearing set and works in conjunction with a matching cup (outer race) to support shaft and hub rotation under heavy loads and higher operating speeds. Licensed HVAC, plumbing, and mechanical service professionals working on axle and differential assemblies rely on precision-grade components like this to restore proper bearing function. The cone geometry allows simultaneous management of thrust and radial forces, making it well suited for front axle and differential service positions.

The LM102949 cone is used in front axle and differential applications on medium-duty and light-duty vehicles. Based on application data included with this part, fitment includes front axle differential service on FW-RWD configurations for MD platforms spanning 1988 through 2017, as well as 4WD front axle differential service on MIT TK applications from 2006 through 2008. This bearing cone is sold as a single unit and is intended for professional installation in axle, differential, and hub assemblies where precise load management is required.

Key Features

• Tapered roller design supports simultaneous radial and axial load management
• Engineered for higher operating speeds and extended service life in drivetrain positions
• Inner cone component matches Timken cup for a complete, precision-fitted bearing set
• Compact envelope delivers durability without excessive space requirements
• Sold individually as one cone; replacement of both cone and cup at the same time is strongly recommended

Compatibility

Fits front axle differential service on FW-RWD MD platforms (1988-2017) and 4WD front axle differential applications on MIT TK platforms (2006-2008). Always verify fitment against the specific assembly before installation.

Installation Notes

Installation should be performed by a qualified drivetrain or mechanical service technician. Before servicing, de-energize all related systems and safely support the vehicle on approved stands. Use a proper bearing driver or press to seat the cone squarely against the shoulder; never drive a bearing with a hammer strike to the rolling elements or cage. Both the cone and cup should be replaced as a matched set to maintain proper load distribution and bearing life.
