What It Helps Correct

• Rear suspension looseness or instability
• Excessive play from worn bushings
• Uneven rear tire wear caused by suspension geometry issues
• Noises from a worn rear upper lateral arm
• Handling changes related to rear suspension wear

Installation Notes and Tips

Install Dorman 526-204 at the rear right upper suspension position only. Verify vehicle year, make, and model before installation, and inspect adjacent suspension components for wear that could affect alignment. Because this is a bolt-on replacement arm, proper torque and a post-installation alignment check are recommended after service on 2017-2020 Kia Optima and 2016-2019 Hyundai Sonata applications.

Dorman designs this lateral arm as a precision-engineered replacement and subjects it to testing to support reliable OE-style service on the listed vehicles. Part number 526-204 is built to meet standard replacement needs for the rear suspension on select Hyundai Sonata and Kia Optima models.
