Restore tight, quiet steering and control with the MOOG Chassis Products Suspension Control Arm and Ball Joint Assembly RK80539, a Front Left Lower unit that combines the control arm, bushings, and integrated ball joint in one assembly.

• Carbon-fiber bearing: Induction-hardened studs paired with a patent-pending carbon fiber-reinforced bearing reduce socket friction versus typical non-reinforced bearings for longer socket life.
• Optimized bushings: Engineered for quiet operation and resistance to wear, salt, road grime, and oils.
• Enhanced strength & corrosion protection: Heat treated to match or exceed OE requirements; coated studs with e-coated cast iron and steel control arms help inhibit premature deterioration.
• Hardware included: Comes with the necessary hardware, with precision tolerances for straightforward installation and steering alignment.

The ball stud shape is designed to support fatigue life and accommodate suspension movement. Worn control arms or ball joints can produce clunking on acceleration or over uneven roads, loose steering, or uneven tire wear — if the original is the cause, this assembly replaces it.
