Installation

Rear axle shaft replacement requires lifting and supporting the vehicle safely, removing the wheel and brake assembly, disconnecting the axle from the differential and hub, and installing the new unit. This is an intermediate-to-advanced repair. Professional installation by a qualified technician is strongly recommended to ensure proper torque specs and drivetrain alignment. Always inspect CV boots, clips, and related hardware at the time of installation.
