Installation Notes and Tips

Verify the rear upper inner forward position before ordering, since this bushing is application-specific. Inspect the control arm and surrounding mounting points for wear, corrosion, or damage before installation. Because mounting hardware is not included, reuse or replace related fasteners as needed based on vehicle condition and service procedure. Professional installation and a post-repair alignment are recommended after suspension work.
