Detailed Description

The TrakMotive TO-8407 CV axle shaft is engineered for front left driveline replacement on 2010-2018 Lexus RX350, 2019-2022 Lexus RX350, 2018-2022 Lexus RX350L, and 2014-2016 Toyota Highlander models listed with the updated design or North America built notes. It is a direct replacement style axle for vehicles that require a 24-spline inboard connection and 30-spline outboard connection, along with the included ABS tone ring for wheel speed sensing.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. The TO-8407 is built as a new replacement axle and is backed by TrakMotive’s limited lifetime warranty. The manufacturer also notes ISO 9001:1007 and TS 16949:2009 certification.

What This CV Axle Helps Address

• Clicking or popping during turns from worn CV joints
• Vibration or shudder during acceleration
• Grease leakage from a damaged axle boot
• ABS warning concerns related to a damaged tone ring or sensor signal path
• Driveline noise caused by excessive axle wear

Installation Notes and Tips

Verify front left fitment by year, model, and build notes before installation. This axle uses a 30 mm hex axle nut with M22 x 1.5 thread size and stake locking type, so confirm the vehicle’s hub and nut specification during service. ABS axles fit non-ABS applications unless otherwise noted, but the included tone ring should still be matched to the vehicle’s original configuration.

For the listed Lexus RX350, Lexus RX350L, and Toyota Highlander applications, compare overall compressed length, spline counts, and joint style against the original axle before installation.
