Product Details

The TrakMotive AAR CV Axle Shaft line is built for OE-style axle replacement where factory geometry and driveline alignment matter. HO-86042 is specified for rear right use on the Acura RDX and Acura TLX applications listed above, with compressed and extended lengths of 29.94 in. and 31.75 in. to match the original driveline dimensions. TrakMotive HO-86042 is also cross-referenced to NCV21096 for the same application.

Common Problems This Part Can Address

  • Clicking or popping from a worn CV joint during acceleration or turning
  • Vibration caused by an axle shaft with excessive wear or imbalance
  • Boot deterioration that can lead to grease loss and joint contamination
  • Driveline noise from spline or joint wear in the rear axle assembly
  • Loss of smooth power transfer to the rear wheel on the listed Acura models

Installation Notes and Tips

Verify rear right fitment by year, model, and OE AAR design before installation. Confirm axle nut thread size, hex size, and locking style match the vehicle specification. Inspect mating seals, hub surfaces, and splines for wear or damage during replacement. Because this axle uses a stake-style axle nut, follow the vehicle service procedure for proper tightening and staking.
