Detailed Description

FAG 102549 is a rear drive axle shaft repair bearing used in driveline and axle service where the original bearing has worn, become noisy, or no longer maintains proper shaft support. FAG develops and produces roller bearings, spherical bearings, and plain bearings for a broad range of applications, and this bearing reflects that engineering focus with application-specific dimensions and broad vehicle coverage. It is listed for rear use on vehicles such as Ford Mustang, Ford F-150, Dodge Ram 1500, Jeep Cherokee, and Chevrolet Blazer, along with many additional truck, van, SUV, and passenger car platforms.

For fitment-based searches, this part is commonly referenced as a rear drive axle shaft repair bearing for 2005-2014 Ford Mustang, rear; 1994-2006 Dodge Ram 1500, rear; and 1993-2001 Jeep Cherokee, rear. The FAG 102549 part number is also used across multiple interchange catalogs, making it easier to verify the correct bearing during axle repair work.

What It Is Used For

• Rear axle bearing noise from a worn drive axle shaft support
• Axle shaft play caused by bearing wear or surface damage
• Rear driveline vibration related to bearing deterioration
• Service repairs on rear axle assemblies with the listed dimensions
• Replacement during axle shaft or differential service on supported vehicles

Installation Notes and Tips

Confirm the rear axle configuration, ring gear size, and bearing dimensions before ordering. Several listed applications include axle-specific notes such as 8.25 in., 8.375 in., 8.50 in., 8.80 in., 9.25 in., or 10.50 in. ring gear references, so matching the vehicle alone is not enough. Verify the old bearing measurements against the FAG 102549 dimensions and compare the application notes for your exact Ford, Dodge, Jeep, or Chevrolet rear axle setup.

For best results, inspect the axle shaft, bearing seat, and related seals during service so the replacement bearing is installed on a clean, properly measured surface.
