Detailed Description
TrakMotive NI-8725 is a front right CV axle shaft engineered for the Infiniti QX50 platform across 2019, 2020, and 2021 model years.

What It Helps Address

- Grease leakage from a torn or deteriorated boot
- Excessive play in the front right driveline assembly
- Loss of smooth power transfer to the front wheel
Installation Notes and Tips
Verify front right fitment by year and configuration before installation. Confirm spline counts, axle nut thread size, and compressed length against the removed part. Because this axle does not include an ABS tone ring, match the vehicle’s ABS setup before ordering. Use proper torque procedures and replace any worn related hardware or seals as needed during service.
