Detailed Description

TrakMotive NI-8649 is a CV axle shaft for front right driveline replacement on 2013 Infiniti G37, 2015 Infiniti Q40, 2016-2019 Infiniti Q50, and 2017-2018 Infiniti Q60. This axle shaft is configured with a 25-spline inboard side, 27-spline outboard side, and a 23.19-inch compressed length to match the listed applications. The included axle nut uses a hex head, M24 x 1.5 thread, and cotter pin locking style. TrakMotive identifies this part as a new component and notes that ABS axles fit non-ABS applications unless otherwise noted.

The TrakMotive CV Axle Shaft line focuses on replacement driveline components for passenger vehicles, and NI-8649 follows that product line approach with application-specific dimensions and joint styles. This part cross-references 39100JK50B and 391004HK1A for the same application.

What It Helps Address

• Clicking or popping during turns from a worn front right CV axle
• Vibration under acceleration caused by axle wear or imbalance
• Torn or deteriorated axle boot conditions
• Grease leakage from a failing constant velocity joint
• Driveline noise from damaged splines or joint wear

Installation Notes and Tips

Verify front right fitment by year, model, and drivetrain configuration before installation. Confirm axle nut thread size, spline count, and compressed length against the removed part to ensure proper match. Inspect the hub, seals, and surrounding suspension components during replacement, and torque the axle nut to the vehicle manufacturer’s specification.

Quality Assurance

TrakMotive states that this axle shaft is backed by a limited lifetime warranty. The company also notes ISO 9001:1007 and TS 16949:2009 certification, supporting controlled manufacturing and quality processes.
