  • Addresses issues such as uneven tire wear caused by faulty control arms
  • Eliminates clunking noises or vibrations from deteriorated bushings
  • Restores proper wheel alignment and handling performance
  • Improves overall suspension stability and vehicle safety

Installation Notes and Tips

Installation of the Dorman 521-418 control arm requires removal of the old control arm and proper alignment of the new part. Since the ball joint is not included, ensure compatibility and availability of the correct ball joint for your Acura TL or TSX. The control arm’s bushings are pre-installed, but verify that all mounting points are clean and free of debris before installation. Professional alignment after installation is recommended to maintain proper suspension geometry and tire wear.
