The arm uses steel tubular construction and includes bushings with neoprene rubber material. Delphi subjects its steering and suspension components to extreme temperature and salt-spray testing, along with dimensional and material checks, to support consistent fitment and long-term service in demanding road conditions.

Common Repair Applications

• Front-end clunking or looseness from worn control arm bushings
• Uneven tire wear caused by suspension geometry issues
• Steering wander or reduced directional stability
• Excessive play in the front right lower suspension point
• Replacement after corrosion, bushing wear, or structural damage

Installation Notes and Tips

Verify vehicle year, model, and front right lower position before installation. This control arm does not include mounting hardware, a grease fitting, or a ball joint, so inspect related suspension components and replace worn hardware as needed during service. A professional alignment is recommended after installation to restore proper suspension angles and tire wear characteristics.

Quality Assurance

Delphi uses OE-focused engineering, dimensional analysis, and material validation to support aftermarket fit and performance. The TC3782 is tested for temperature extremes and salt-spray exposure to help confirm durability in real-world suspension service.
