Dorman - OE Solutions Suspension Control Arm P/N:521-855
Dorman 520-855 front left lower control arm for the 2001-2005 Hyundai Sonata and other vehicles connects the front left wheel to the vehicle and lets the suspension move. This Dorman control arm is a standard replacement grade, non-adjustable arm.
A clunk over bumps, loose or wandering steering, or uneven tire wear can mean a worn front left lower control arm. These signs alone do not prove the arm is at fault, since a worn sway bar link can clunk too. This listing is one arm for the front left, and both front sides are normally replaced together.
It is a direct-replacement lower control arm for the 2001-2005 Hyundai Sonata, the 2001-2006 Kia Optima, the 2004-2006 Kia Amanti and many other vehicles.
