Detailed Product Description

This Dorman suspension control arm (part number 521-824) is constructed using a casting and forging process to ensure structural integrity and long-lasting performance. The iron material provides the necessary strength to handle suspension loads, while the coated black finish helps protect against rust and environmental wear. The control arm includes a single rubber bushing with a 14.3 mm inside diameter and 39.6 mm outside diameter, designed to absorb road vibrations and reduce noise. The bushing length measures 92 mm, and the control arm’s overall length is 262.5 mm, ensuring proper alignment and fitment on compatible Volvo models.

Compatible Vehicles and Applications

This control arm is specifically designed for use on Volvo 740, 760, 780, 940, and 960 models. It is ideal for replacing worn or damaged suspension control arms to restore proper handling and suspension geometry. The welded ball joint mounting type requires a separate ball joint installation, allowing for flexibility in suspension maintenance and repair.

Common Issues Addressed by This Control Arm

• Excessive suspension play or looseness
• Uneven tire wear due to misalignment
• Clunking or knocking noises from worn bushings
• Reduced steering stability and control
• Vibration and harshness transmitted through the suspension

Installation Notes and Tips

Installation of the Dorman 521-824 control arm requires removal of the old control arm and proper alignment of the new part. Since the ball joint is not included, ensure the correct ball joint is installed separately. The press-in end and bushing linkage end should be carefully pressed into place using appropriate tools to avoid damage. It is recommended to have a professional alignment performed after installation to maintain optimal suspension geometry and vehicle handling.
