TrakMotive HO-86045 Rear Left CV Axle Shaft

The TrakMotive AAR CV Axle Shaft HO-86045 is a premium replacement axle for the rear left position on select Acura MDX models. It is built for 2022-2023 Acura MDX applications with OE AAR design, and it includes the axle nut for a cleaner service replacement.

The AAR CV Axle Shaft line focuses on application-specific driveline fitment and OE-style construction. For Acura MDX rear left service, HO-86045 provides the correct spline counts, compressed and extended lengths, and non-ABS configuration details needed for a direct replacement.

Key Features

  • Fits 2022-2023 Acura MDX, rear left
  • TrakMotive HO-86045 CV axle shaft for driveline and axle service
  • OE AAR design for the listed application
  • Premium grade construction
  • Includes axle nut with M26x1.5 thread size
  • Non-ABS axle configuration with no tone ring included
  • 25 inboard splines and 30 outboard splines
  • Thermoplastic boots on the inboard and outboard joints

Detailed Description

HO-86045 is a rear left CV axle shaft for the 2022-2023 Acura MDX, engineered around the OE AAR layout for the listed vehicle application. It uses a male inboard joint with spline connection, a conventional outboard joint, and the specified axle dimensions to match the original driveline geometry. The axle measures 30.94 inches compressed and 32.81 inches extended, helping maintain proper suspension travel and axle engagement on the Acura MDX rear left position. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

What It Helps Repair

  • Clicking or popping from a worn CV joint
  • Vibration during acceleration from axle wear
  • Grease leakage from damaged axle boots
  • Axle play caused by worn splines or joint wear
  • Driveline noise from a failing rear left axle assembly

Installation Notes and Tips

Verify the rear left position, spline count, axle nut thread size, and non-ABS configuration before installation. The included axle nut uses a stake-style locking design with a 35 mm hex size. Confirm compressed and extended length against the original axle to ensure proper fit on the Acura MDX.

Quality Assurance

TrakMotive lists this axle shaft under its AAR CV Axle Shaft line and states that the company is ISO 9001:2008 and TS 16949:2009 certified. Manufacturer coverage includes a limited lifetime warranty.
