Installation notes and tips

Verify the vehicle position and fitment before installation. Inspect related suspension components, fasteners, and alignment settings during replacement. Because this assembly is pre-greased and includes a grease fitting, service checks should confirm proper lubrication after installation.

Quality assurance
