Function：Ball joints are usually ball and socket design, lubricated with grease and covered with dust boots. Most of the ball joints are now sealed to prevent dust, grit and other impurities from damaging the joint and to prevent maintenance.
How do you know when it's time to replace your control arms？If there is a problem with the ball joint, it is usually necessary to replace the whole assembly. Depending on the type of suspension, most cars have up and down ball joints. Due to the weight of the front, the lower ball joints are usually larger and wear faster.
