Features of the AAR CV Axle Shaft Product Line

The AAR CV Axle Shaft line by TrakMotive focuses on delivering new, high-quality CV axle components engineered for precise fit and function. This product line emphasizes compatibility with specific vehicle makes and models, ensuring that each axle shaft meets the exact specifications required for optimal driveline performance. The SB-8120 model continues this standard by providing a robust neoprene boot and a stake-type locking axle nut to maintain secure connections under demanding driving conditions.

Detailed Product Description

The TrakMotive SB-8120 CV axle shaft features a male inboard joint type with 25 splines and a conventional outboard joint with 27 splines, both utilizing spline shaft connection styles for reliable torque transfer. The included axle nut is a hex head type measuring 1.25 inches (31.8 mm) across the flats, with a height of 0.79 inches (20 mm) and a length of 1.45 inches (36.72 mm). The stake locking mechanism on the axle nut ensures it remains securely fastened during operation. The neoprene boot material provides resistance to wear and environmental factors, helping to protect the CV joint from contaminants and extend service life. This CV axle shaft is a new component, not remanufactured, ensuring consistent quality and performance.

Common Applications and Problem Solving

  • Replacement for worn or damaged CV axle shafts on Subaru Legacy and Outback
  • Addresses issues with axle vibration or clicking noises during turns
  • Resolves grease leakage caused by torn or degraded CV boots
  • Fixes axle nut loosening problems with stake locking design
  • Restores driveline stability and smooth power delivery

Installation Notes and Tips

When installing the TrakMotive SB-8120 CV axle shaft, ensure the axle nut is torqued to manufacturer specifications and properly staked to prevent loosening. Verify spline engagement on both inboard and outboard joints for secure fitment. Inspect the neoprene boot for any damage before installation and replace if necessary. This axle shaft is designed for direct fitment on Subaru Legacy and Outback models, so no modifications should be required.
