Detailed Description

Timken JLM506810 is a differential pinion race engineered for applications that require accurate bearing geometry and durable load handling. Timken tapered roller bearing components are known for managing combined loads while maintaining consistent performance in compact axle and differential assemblies. For service work on a Lexus LX470 or Toyota Land Cruiser, this bearing cup is a direct-fit component for front inner use, while other listed applications include rear outer and rear inner positions on select Dodge, Ford, Land Rover, and Maserati vehicles. This part number, JLM506810, is also cross-referenced by National under the same application.

What It Helps Solve

• Excessive differential or axle bearing noise
• Rough rotation caused by worn bearing races
• Improper bearing support in front inner or rear outer positions
• Wear from heat, load, and mileage in driveline assemblies
• Service issues on Lexus LX470, Toyota Land Cruiser, and other listed vehicles

Installation Notes and Tips

Replace the inner cone and outer cup together to maintain bearing geometry and service life. Verify the bearing dimensions, cup radius, and vehicle application before installation. For fitment-specific service, confirm the correct position such as front inner, rear outer, front, or rear inner on the exact year, make, and model. The JLM506810 is used in applications including 1998-2007 Lexus LX470 front inner, 1998-2007 Toyota Land Cruiser front inner, 1994-2001 Dodge Ram 2500 rear outer with Spicer 80 - 13 in. x 3.5 in. brakes, and 1992-1993 Ford E-350 Econoline Club Wagon rear outer with Spicer 80 Series axle.
