Timken JHM720249 Differential Bearing - Rear Left

Timken differential bearing for heavy-duty axles

The Timken JHM720249 is a differential bearing built for heavy-duty driveline service. It is specified for rear left applications on Ford trucks and medium-duty models equipped with the Rockwell 23180 axle.

Key features

• Tapered roller bearing design for managing radial and axial loads.
• Engineered for higher operating speeds, heavier loads, and extended service life.
• Compact bearing construction for demanding driveline packaging.
• Timken JHM720249 is backed by the brand’s bearing engineering and support expertise.

Detailed description

This differential bearing is part of Timken’s tapered roller bearing lineup, a product family known for handling combined load demands in driveline applications. The JHM720249 is used in rear left positions on Ford CF7000, CF8000, F-600, F-700, F-800, F-Super Duty, C8000, CF6000, FT800, B-600, B-700, B-7000, F-7000, and F-8000 models with the Rockwell 23180 axle. If you are servicing a Ford F-600 or Ford F-700 application, this bearing is selected for the specified axle position and load requirements. This part cross-references Timken (e.g., JHM720249) for the same application.

What it is used for

• Replacing a worn or noisy differential bearing.
• Addressing bearing play or rough rotation in the axle assembly.
• Restoring proper load support in the differential.
• Correcting wear related to high-mileage or heavy-duty service.

Installation notes and tips

Confirm axle identification before ordering, since fitment is tied to the Rockwell 23180 axle. Timken recommends replacing the inner cone and outer cup together to maximize reliability and service life. Verify bearing condition, race wear, and related axle components during service.

Quality assurance

Timken is a recognized global leader in tapered roller bearings, with engineering focused on durability and load management. The JHM720249 reflects that bearing expertise for demanding driveline applications.
