Detailed Product Description

  • Addresses issues such as uneven tire wear caused by faulty control arms
  • Improves vehicle handling and steering response by restoring suspension geometry
  • Eliminates clunking noises from suspension due to deteriorated bushings

Installation Notes and Tips

Installation of the Dorman 521-377 control arm requires basic suspension knowledge and tools. Since the ball joint is not included, ensure your existing ball joint is in good condition or replace it separately. The control arm features a press-in end type and includes the rubber bushing, but mounting hardware is not included, so retain or source necessary bolts and nuts. Proper torque specifications should be followed to maintain suspension integrity. It is recommended to have a professional alignment performed after installation to ensure optimal vehicle handling.
