MOOG Chassis Products Suspension Control Arm P/N:RK643149
MOOG Chassis RK642812 front left lower control arm for the 2013-2016 Audi S8 and other vehicles links the front left wheel to the chassis and lets it move with the suspension.
A clunk over bumps, uneven tire wear or a steering wheel that drifts can mean a worn bushing or a bent arm. If you suspect this suspension control arm, look it over with the car parked and the engine off: cracked or torn rubber and any visible bend are worth finding first, because other suspension parts give similar signs.
It fits the 2013-2016 Audi S8 and the 2011-2015 Audi A8 Quattro, and each takes one on this side. This listing is one arm for the front left; the right side is a separate part, and the two are normally replaced together.
