Keep your front wheel properly located and your steering on-spec with the MOOG RK622203 Front Left Lower Suspension Control Arm and Ball Joint Assembly. This control arm installs as a direct-fit replacement for the 2010-2015 Toyota Prius, 2012-2015 Toyota Prius Plug-in and 2011-2017 Lexus CT200h, integrating the lower control arm, its bushings and a pre-assembled ball joint into a single front-left-lower unit.
MOOG premium control arms are engineered for structural strength and corrosion protection. Key features:
- Easy to install: Precision tolerances deliver a fit right out of the box and support proper steering alignment.
- Optimized bushings: Bushings tuned for quiet operation and resistance to wear, salt, road grime and oils.
- Durable ball stud: The ball stud shape supports fatigue life, compensating for sag and adding extra swing when needed.
- Corrosion protection: Coated studs plus e-coated cast iron and steel construction help inhibit premature deterioration; heat-treated to OE-level requirements.
If a worn ball joint or failed bushing on the original arm is behind clunking over bumps, loose or wandering steering, or uneven tire wear, replacing this assembly renews those pivot points in one part. An alignment is recommended after installation.
