Yes, it is generally recommended to perform an alignment after replacing control arm bushings. Control arm bushings play a crucial role in maintaining the correct alignment of the suspension system. When these bushings wear out, it can lead to misalignment, causing uneven tire wear, reduced handling, and potentially unsafe driving conditions.

Replacing the control arm bushings restores the stability and proper functioning of the suspension system. However, the act of removing and reinstalling the control arms can slightly alter the alignment settings. Even small changes in alignment can impact camber, caster, and toe angles, affecting the vehicle's tire wear, steering response, and overall handling.

To ensure optimal performance and safety, it is recommended to have a professional perform an alignment after replacing control arm bushings. They will use specialized equipment to measure and adjust the suspension angles to the manufacturer's specifications. This helps to extend tire life, improve handling, and maintain proper alignment for safe driving.
