A PEUGEOT 206 Control arm act as the link between steering knuckle and vehicle body in the case of independent wheel suspensions. Dependent on their design, there are two-point and three-point links; less frequently also four-point links. They provide for a precise wheel control thus ensuring optimum tire use in all driving conditions.
PEUGEOT 405 Ball joints serve as the pivot points between the steering knuckle and lower and upper control arm suspension. This pivot action allows the suspension to travel up and down and tires to turn left to right. Ball joints support the entire weight of the vehicle.
Ball joints are located in the front suspension an inch or so behind the front tire. The lower ball joint is the pivot joint between the lower control arm and steering knuckle. The upper ball joint, if you have one is the pivot joint between the upper control arm and steering knuckle.
Control arms should be placed in shelf, out of high temperature and humidity, and no other lubricant should be added to the ball joint when installing. Semiannual inspection is recommended for dust cover tear and excessive play.
