Wheel Bearing for Heavy-Duty Rear Inner Applications

InMotion WT45291 is a taper wheel bearing built for rear inner service in a wide range of Dodge, Ram, and Plymouth heavy-duty trucks and vans. With a 2.25 in. inside diameter, 1.219 in. width, and cylindrical bearing geometry, it is built for smooth rotation, reduced friction, and stable load support in demanding driveline use.

2.25 in. inside diameter (57.2 mm)
1.219 in. width (31 mm)
0.25 in. cone radius (6.4 mm)

Universal-style bearing design for multiple industrial and automotive uses
Part number WT45291 for ordering and cross-reference

Detailed Description

WT45291 is an InMotion wheel bearing engineered for rear inner positions where consistent rotational performance matters. It is listed for 2011-2018 Ram 3500 rear inner applications with dual rear wheels, 2003-2010 Dodge Ram 3500 rear inner applications with dual rear wheels, and multiple Dodge heavy-duty truck and van configurations including Ram 2500, Ram 3500, B350, D250, D350, W250, and W350. This part number, WT45291, is also associated with older Spicer 60 Heavy Duty Axle and Spicer 71 Axle setups, making it a practical service part for classic and late-model heavy-duty driveline repair.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

Rear wheel bearing noise in Dodge Ram 3500 and Ram 2500 rear inner service
Excess friction at the axle end of heavy-duty rear driveline assemblies
Loose or unstable wheel rotation caused by worn bearing surfaces
Service needs on dual rear wheel Ram 3500 applications
Maintenance on older Dodge and Plymouth trucks with Spicer axle configurations

Installation Notes and Tips

Verify axle type, brake package, and rear inner position before ordering. Confirm the bearing dimensions against the original part, especially on 1975-2018 Dodge, Ram, and Plymouth applications with Spicer 60 Heavy Duty Axle, Spicer 71 Axle, or dual rear wheel configurations. Professional installation and proper bearing preload or adjustment procedures are recommended for heavy-duty wheel bearing service.
