QU50397 Timken® Bearing Cup is most commonly used in axle differential applications. This is a First Class, original equipment quality Bearing Cup that meets or exceeds all vehicle manufacturer specifications making it the top choice for heavy-duty applications like yours. Country of origin may vary as Timken produces Bearings in plants located around the globe, however QU50397 is almost always made in either Canada or the United States.
Always replace the cup and cone at the same time.
This cup is usually used on differential applications so a cup installer is not needed, however, if you need an Installer Plate for your application, order QT1804 Bearing Cup Installer separately.
Rebearing service procedures are covered in my TM4400 Pinion and Differential Bearing Service on Dana-Spicer Monobeam Axles.
Vehicle Applications too numerous to list.
This Cup is used on the differential of Dana 60, 61, and 70 axles plus many corporate axles and for some wheel bearing applications. Refer to the specific vehicle page for your truck from the links list above.
