There are two sets of control arms, uppers and lowers, that work together to keep the axels and attached wheel hubs properly aligned and in a fixed radius of articulation. Made of durable materials and protected by tough rubber bushings, these devices typically last for years without incident. But when a control arm does bend or break, it can cause a whole host of problems, including increased road noise, premature wear, and poor steering and handling. Because they traverse difficult terrain, many serious off-roading enthusiasts replace their stock control arms and accessories with heavy-duty fixed or adjustable arms.
