Applications

The C-4308 Bearing Cup Installer is primarily used for installing rear pinion bearing cups in Chrysler 8 1/4" and 9 1/4" axles. These axles have been extensively used in various Chrysler Group vehicles, including passenger cars, trucks, and vans since the early 1970s.

This versatile tool also applies to several Dana axle models, specifically the 186FIA, 216RBA, 226RBA, and 286RBI. The Dana 186FIA (also known as Dana 30a) is an independent front axle commonly found in Jeep Liberty models. Dana 226RBA axles are associated with Jeep Grand Cherokee and Commander models. The 286RBI axle (often a Dana 80 or similar heavy-duty unit) is typically found in larger Dodge Ram 2500 and 3500 trucks.

Furthermore, the C-4308 is essential for servicing NV4500 and NV5600 transmissions. The NV4500 is a heavy-duty 5-speed manual transmission used in GM and Dodge trucks from the early 1990s through the 2000s, known for its robust internals. The NV5600 is a heavy-duty, close-ratio 6-speed manual transmission primarily used in Dodge Ram 2500 and 3500 series trucks with Cummins engines from 1999 to 2005.

This tool's usage covers a broad range of Chrysler Group vehicles from 1985 through current models, with specific applications noted between 2006 and 2012 for systems related to Transmission and Transfer Case (System 21) and Differential and Driveline (System 3).
