Which component's wear could lead to changes in camber and caster, causing steering pull?

The wear of control arm bushings can significantly impact the alignment of the suspension components, particularly camber and caster angles. Control arm bushings are designed to provide a pivot point and maintain proper alignment of the control arms, which are critical for keeping the vehicle’s wheels positioned correctly relative to the body of the vehicle and the road.

When control arm bushings wear out, they can lose their ability to hold the control arm in its proper position. This loss of precise positioning can alter the angles of camber and caster, resulting in uneven tire wear and potentially causing the vehicle to pull to one side when driving. A change in these suspension angles can also compromise handling and stability.

In contrast, while ball joints, track rods, and shock absorbers are also important components of the suspension system, their primary functions differ. Ball joints allow for movement of the control arms and affect steering response, while track rods help maintain wheel alignment and direction but are less directly involved with camber and caster adjustments. Shock absorbers primarily dampen the motion of the vehicle's suspension system and maintain ride comfort. Therefore, while they all play vital roles in steering and suspension, the specific link between wear in control arm bushings and changes in camber and caster directly correlates
