Product Details
TrakMotive HO-8638 is engineered for direct replacement service on the front right side of select Honda Pilot and Acura MDX vehicles.

This part cross-references 44305TZ5A11 for the same application.
As part of the TrakMotive AAR CV Axle Shaft line, HO-8638 is built for applications that require OE-style fitment and the correct axle geometry for the vehicle platform. It is a direct-fit option for 2019-2020 Honda Pilot front right, 2016-2018 Honda Pilot front right, and 2014-2015 Acura MDX front right service needs.
Common Issues This Part Can Address
- Clicking or popping from a worn CV joint during turns
- Vibration or shudder caused by a damaged axle shaft
- Torn boot conditions that expose the joint to contamination
- Axle noise from spline or joint wear
- Loss of driveline smoothness at the front right corner
Installation Notes and Tips
Verify the axle nut thread size, hex size, and locking style before installation. Confirm the vehicle uses the listed front right configuration and compare spline counts and compressed length to the original part. Because this axle does not include an ABS tone ring, confirm the vehicle application does not require one.
