What It Helps Address

• Transmission bearing wear at the countershaft race surface
• Excessive play or looseness in tapered roller bearing support
• Noise caused by a worn or damaged race
• Reduced bearing life from incorrect race dimensions
• Service issues on Chrysler and Dodge rear outer original equipment applications

Installation Notes

Replace the inner cone and outer cup together to maintain bearing geometry and service life. Verify the race dimensions against the original part before installation, and inspect the mating bearing surfaces for scoring, pitting, or contamination. Clean assembly practices matter in manual transmission service, especially on high-load tapered roller bearing components.
