Detailed Product Features and Specifications

This Dorman suspension control arm (part number 522-221) is designed to replace the original equipment part on Mitsubishi Lancer vehicles. The control arm features a single black rubber bushing that measures 39.6 mm in outside diameter and 92 mm in length, providing effective isolation from road vibrations. The boxed steel construction improves durability under normal driving conditions, while the coated finish helps resist rust and corrosion. The ball joint mounting type is welded, and the stud is threaded, allowing for secure ball joint installation (ball joint sold separately). This control arm does not include mounting hardware or grease fittings, so those components must be sourced separately if needed.

Common Suspension Issues Addressed

• Worn or damaged control arm bushings causing steering instability
• Corroded or bent control arms affecting wheel alignment
• Excessive suspension noise due to degraded bushings
• Uneven tire wear linked to faulty suspension components
• Reduced handling performance from compromised control arm integrity

Installation Notes and Tips

When installing the Dorman 522-221 control arm on a Mitsubishi Lancer, ensure the vehicle is securely lifted and supported. Remove the old control arm carefully, noting the orientation of the bushings and ball joint mounting points. Since the ball joint is not included, transfer the existing ball joint or install a new compatible unit. Verify that the bushing is properly seated and that all bolts are torqued to manufacturer specifications. It is recommended to perform a wheel alignment after installation to maintain proper suspension geometry and handling.
