Product Details

TrakMotive HO-8591 is an AAR CV axle shaft for the front right side of the Acura TLX. It fits 2015-2019 Acura TLX, front right, and 2020 Acura TLX, front right. The updated design for the 2015-2019 Acura TLX application supports direct replacement service, while the 2020 Acura TLX listing notes inspection of the intermediate shaft if damage is present during CV axle replacement. This part cross-references OE number 44305TZ4A01 for the same application.

As part of TrakMotive’s AAR CV Axle Shaft line, HO-8591 is built for driveline repair where the original axle has worn splines, joint play, or boot failure. The listed dimensions, spline counts, and axle nut specifications help match the OE-style fitment requirements for Acura TLX front right service.

Common Repair Uses

  • Clicking or popping during turns from a worn CV joint
  • Vibration under acceleration from axle wear or imbalance
  • Grease leakage from a damaged axle boot
  • Clunking or looseness from spline or joint wear
  • Front right driveline replacement after axle damage

Installation Notes

Verify front right fitment before installation on the Acura TLX. Confirm axle nut thread size, hex size, and compressed length against the original part. When replacing a CV axle on the 2020 Acura TLX, inspect the intermediate shaft for damage and replace it if needed. Always follow vehicle-specific torque procedures and service manual steps for axle nut staking and final assembly.

Quality Assurance

TrakMotive states that this axle is backed by a limited lifetime warranty and produced by an ISO 9001:1007 and TS 16949:2009 certified company.
