MOOG Chassis Products Suspension Control Arm P/N:RK643771
MOOG Chassis Products RK643341 rear left lower control arm for the 2015-2018 Hyundai Sonata and other vehicles controls how the rear left wheel moves as the suspension travels.
A clunk from the rear over bumps, uneven rear tire wear or a wandering rear end can mean this suspension control arm or its bushings are worn, though a tired shock absorber or a worn wheel bearing can be behind the same signs. This listing is one piece for the rear left, and both sides are normally replaced together.
It fits the 2015-2018 Hyundai Sonata, and the same control arm fits the 2016-2017 Kia Optima. It is engineered to match or exceed OE requirements.
