Product Details

TrakMotive AD-8189 is engineered as a CV axle shaft for rear applications where the original axle needs replacement without changing the vehicle’s driveline geometry or ride characteristics. The bolt-on inboard joint and spline-style outboard connection match the listed Audi fitments, including 2012-2018 Audi A6 Quattro, 2011-2018 Audi A8 Quattro, and 2013-2017 Audi S6 rear applications. Additional coverage includes 2013-2016 Audi Q5 and S7 rear, 2014-2016 Audi SQ5 rear, and 2014-2017 Audi RS7 rear.

TrakMotive’s CV Axle Shaft line focuses on direct-fit driveline replacement parts, and this AD-8189 axle follows that approach with application-specific dimensions and joint design. It is also listed for 2017 Audi Q5 and SQ5 rear applications with VIN FP (7th and 8th digit) and for 2014-2017 Audi A7 Quattro and 2013-2014 Audi S8 rear applications without torque vectoring differential.

Common Problems This Part Can Address

• Clicking or popping from a worn rear CV joint
• Vibration during acceleration from axle wear
• Boot damage that has led to grease loss and joint contamination
• Excessive driveline play in the rear axle assembly
• Noise or binding caused by a fatigued OE-style axle shaft

Installation Notes and Tips

Confirm rear position, drivetrain configuration, and any VIN-specific notes before ordering. This axle does not include an axle nut, and the axle bolt uses a 17 mm hex with M16x1.5 thread and 85 mm length. ABS tone ring is not included, and ABS axles fit non-ABS applications unless otherwise noted by the vehicle listing.

Verify spline count, bolt pattern, and compressed length against the original axle before installation. For Audi A6 Quattro, A7 Quattro, A8 Quattro, Q5, RS7, S6, S7, SQ5, and S8 applications, matching the listed notes is important for proper fitment.

Quality Assurance

TrakMotive states that this CV axle shaft is backed by a limited lifetime warranty. The brand also notes ISO 9001:2008 and TS 16949:2009 certified manufacturing standards for this product line.
