Product Details

TrakMotive GM-8393 is engineered as a direct replacement CV axle shaft for 2018-2019 Buick LaCrosse, front left, 2017-2018 Chevrolet Malibu, front left, and 2016 Chevrolet Malibu, front left with the updated design and new style VIN Z (4th digit) application.

What This Part Helps Address

• Clicking or popping noises during turns from a worn CV joint
• Vibration felt through the drivetrain from a damaged axle shaft
• Torn or deteriorated boot material that can expose the joint to contamination
• Axle shaft wear that affects front-wheel-drive power transfer
• Fitment issues when replacing the front left axle on the listed Buick LaCrosse and Chevrolet Malibu models

Installation Notes

Confirm front left fitment, spline count, and axle nut thread size before installation. This axle uses a hex-style axle nut with cotter pin locking and includes no ABS tone ring. ABS axles fit non-ABS applications unless otherwise noted, so verify the vehicle’s original configuration against the listing details before service. Professional installation and proper torque procedures are recommended for driveline repairs.
