Signs of Damage: Through noises (squeals, squeaks, rumbles); Poor driving performance; Increasingly vague and inaccurate steering; Uneven tire wear.

I. How to Detect Damage to the Control Arm:

Use a pry bar to shake the tire up and down/left and right, observing the looseness gap of the control arm ball joint; observe whether there are cracks and damage to the bushings and dust covers.

II. Common Damage Cases of Control Arms:

Cracks in the rubber bushings; Damaged or missing ball joint dust covers; Loose or broken ball joints; Deformed or broken arm bodies.

III. Replacement Cycle of Car Control Arms:

The replacement cycle of car control arms is typically around three years due to the tendency of the bushings to age and crack. Once damaged, the vehicle will exhibit a series of problems such as veering and instability, even after a four-wheel alignment. If you carefully inspect the chassis, damage to the rubber bushings is easy to detect. Generally speaking, control arms should be replaced every three years or so. Control arms of different materials in car suspensions have different service lives. When we go to a 4S shop for maintenance, we can ask the technicians if we need to replace the control arms. Additionally, when one control arm encounters a problem, it can also affect other connecting rods or control arms. Therefore, after a wheel has suffered a significant impact, even if no issues are visually apparent, it is necessary to promptly inspect the control arms and related components.
