Detailed Description

Timken JLM506849 is a transfer case output shaft bearing engineered as a tapered roller bearing component for drivetrain assemblies that must manage both side load and thrust load. The bearing’s 55.00 mm inside diameter and 23.00 mm cone width make it a precise service option for applications that require stable shaft support and consistent rotational performance. This part number is also referenced as National JLM506849.

Vehicle coverage includes 1994-2001 Dodge Ram 2500 rear outer applications with Spicer 80 and 13 in. x 3.5 in. brakes, 1992-1993 Ford F-350 rear outer Spicer 80 Series axle applications, 1992-1993 Ford E-350 Econoline Club Wagon rear outer Spicer 80 Series axle applications, 1987-1988 Land Rover Range Rover front LT230 applications, and 1979-1986 Maserati Quattroporte rear inner applications. The Timken JLM506849 also appears in select Cadillac rear applications listed for manual transmission input shaft bearing, 9.5 in. ring gear, axle differential bearing, and seal kit service.

Common Problems This Bearing Can Address

• Excessive shaft play in transfer case or axle-related bearing locations
• Noise from worn tapered roller bearing surfaces
• Rough rotation caused by bearing wear or contamination
• Loss of load control in radial and axial directions
• Service issues in rear outer, rear inner, or front drivetrain bearing positions

Installation Notes and Tips

Replace the cone and cup together to maintain bearing geometry and service life. Confirm the bearing position, axle or transfer case configuration, and dimensions before installation, especially on applications such as Dodge Ram 2500 rear outer, Ford F-350 rear outer, and Land Rover Range Rover LT230 front service. Clean the housing thoroughly and inspect the shaft, race, and sealing surfaces for wear before assembly.

Quality Assurance

Timken is recognized globally for tapered roller bearing engineering, with products built to handle higher speeds, heavier loads, and long service intervals. The JLM506849 reflects that bearing expertise in a compact drivetrain service part for confirmed applications.
