• Outside diameter: 84.00 mm (3.307 in.)
• Width: 17.50 mm (0.689 in.)
• Bearing cup radius: 1.50 mm (0.059 in.)
• Built for applications that require both radial and axial load handling
• Cross-reference: National JLM704610

Detailed Description

Timken JLM704610 is a differential race used in rear axle assemblies across many classic and late-model trucks and vans, including Dodge Ram 1500, Dodge Dakota, Dodge Durango, and Ram 1500 applications. It also serves select Chrysler, Plymouth, and Mitsubishi rear differential setups. Timken’s tapered roller bearing design is engineered for durability in compact spaces, helping maintain proper bearing support under load. For reliable service life, the inner cone and outer cup should be replaced together during bearing work. This part number, JLM704610, is a direct fit reference for technicians servicing rear differential bearing assemblies on vehicles such as the Ram 1500 and Dodge Dakota.

What It Helps Address

• Rear differential bearing noise
• Excessive play or looseness in the pinion bearing area
• Wear from heat, load, or mileage in tapered roller bearing assemblies
• Improper bearing surface condition during differential rebuilds
• Service needs on rear axle setups in Dodge Ram 1500 and Dodge Dakota models

Installation Notes and Tips

• Confirm axle and ring gear configuration before ordering, especially on Dodge Ram 1500, Dodge Dakota, and Ram 2500 applications.
• Several listed fitments note that the differential pinion race must be used with the differential pinion seal for proper installation.
• Replace the matching cone and cup together to maintain bearing geometry and service life.
• Verify dimensions against the original race before pressing into the housing.

Quality Assurance

Timken is recognized globally for tapered roller bearing engineering and technical support. The JLM704610 differential race reflects that focus with load-handling capability for rear axle service and precise dimensional control for differential rebuild work.
