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.
