Dorman - OE Solutions Suspension Control Arm and Ball Joint Assembly P/N:521-057
Dorman - OE Solutions Suspension Control Arm and Ball Joint Assembly P/N:521-057
$87.99

Replace a worn front left lower arm and its ball joint together with the Dorman control arm 521-057 from Dorman - OE Solutions, which arrives with the ball joint and bushings already installed. It is a direct replacement for the original assembly on the 2001-2006 Hyundai Santa Fe. See the Buyer's Guide tab for engine-level fitment.

As a Dorman lower control arm, it connects the wheel assembly to the chassis so the wheel can travel up and down, while the ball joint gives the steering a pivot point. Dorman evaluates the design with the aim of a smooth ride, directional stability and predictable dynamics.

  • Trustworthy replacement: Directly replaces the original assembly on specific vehicle applications.
  • Pre-installed components: Each assembly comes with the ball joint and bushings already in place, saving time and labor.
  • Quality engineering: Put through industry-leading testing intended to deliver a smooth, stable and safe ride.
  • Rust and corrosion resistance: Additional coatings help protect against rust and corrosion.

This arm is for the front left lower position. Replacing the right side at the same time is recommended when both arms are worn. Signs that a control arm or ball joint may need replacing include clunking over bumps, loose or wandering steering, and uneven tire wear. Other suspension and steering parts can cause the same symptoms, so diagnose the cause before replacing.
