TrakMotive CV Axle Shaft Product Line Details

The TrakMotive CV Axle Shaft product line focuses on delivering new, high-quality constant velocity axle shafts designed for direct replacement applications. This line emphasizes precise engineering with bolt-on inboard joints and conventional outboard joints to maintain factory specifications. The use of neoprene boots and self-locking axle nuts ensures long-lasting performance and secure installation.

Technical Specifications and Features

The AD-8138 CV axle shaft features a hex head axle nut measuring 36 mm across flats with a height of 21.5 mm and a length of 41.5 mm. The axle nut is self-locking, providing secure fastening without additional locking mechanisms. The inboard joint uses a bolt-on connection style with six M10*1.5 Allen head bolts, each 55 mm in length, ensuring a robust and reliable attachment. The neoprene boot material offers resistance to wear and environmental factors, protecting the joint from contaminants. The outboard joint is conventional with 30 splines, designed to fit precisely with the vehicle’s hub assembly. The overall compressed length of 20.67 inches (525 mm) matches OEM specifications for proper driveline geometry.

Applications and Problem Solving

• Replacement for worn or damaged CV axle shafts on Audi Q7, Porsche Cayenne, and Volkswagen Touareg
• Resolves issues related to axle shaft vibration or clicking noises during turns
• Addresses grease leakage or torn CV boots causing joint contamination
• Fixes axle nut loosening problems with included self-locking hex nut
• Restores driveline integrity and smooth power transfer to wheels

Installation Notes and Tips

Installation requires removal of the old axle shaft and proper torque application of the included self-locking hex axle nut (M24*1.5 thread). The bolt-on inboard joint uses six Allen head bolts (M10*1.5 thread), which should be tightened to manufacturer torque specifications. Ensure the neoprene boot is properly seated to prevent contamination. Verify the overall compressed length matches the vehicle’s requirements to maintain suspension and driveline alignment.
