Detailed Description

TrakMotive CV Axle Shaft AD-8191 is engineered for the rear driveline on the Audi Q7, covering 2017-2022 model years. The axle uses a bolt-on inboard joint and a spline-style outboard connection with an Audi-style spline bolt, matching the OE-style layout needed for this application. TrakMotive positions this CV axle shaft within its CV Axle Shaft line for direct driveline replacement work where maintaining factory ride characteristics matters. This part cross-references OE-style numbers such as 4M0501203D and NCV20002K for the same application.

What It Helps Address

• Clicking or popping noises from a worn rear CV joint
• Vibration during acceleration from a damaged axle shaft
• Grease leakage from torn or deteriorated boots
• Excessive play in the rear driveline
• Loss of smooth power transfer to the rear wheels

Installation Notes and Tips

Verify rear-position fitment before installation on the Audi Q7. Confirm axle bolt size, thread pitch, spline count, and overall length against the removed part before assembly. This axle does not include an axle nut, and ABS tone ring hardware is not included. Because the inboard and outboard joint designs are application-specific, compare the OE axle configuration to the replacement part before final installation.

Quality Assurance

TrakMotive manufactures this axle as a premium-grade replacement from an ISO 9001:2008 and TS 16949:2009 certified company. The AD-8191 is backed by a limited lifetime warranty.
