Detailed Description

Delphi TC6934 is engineered as a direct replacement suspension control arm assembly for the rear left upper rearward location. It includes the ball joint, bushings, dust boot, mounting hardware, and locking nut, reducing the need to source separate components during service. The arm uses a steel construction with black coating, while the ball joint and boot materials are selected for durability in demanding underbody conditions.

Delphi applies OE-focused dimensional and material analysis to help maintain proper fit and suspension geometry. The brand also subjects steering and suspension components to temperature extremes and extended salt-spray exposure during validation, supporting consistent performance in harsh environments. For Genesis G80 and Hyundai Genesis rear suspension service, TC6934 provides a complete assembly solution that matches the original mounting position.

Common Problems This Part Can Address

• Excessive rear suspension play or looseness
• Clunking or knocking from the rear left suspension area
• Worn or cracked bushings
• Ball joint wear at the rear upper rearward control arm location
• Uneven rear tire wear caused by suspension geometry issues

Installation Notes and Tips

Verify the rear left upper rearward position before installation and compare the original arm length, bushing dimensions, and ball joint orientation to the replacement part. Because this assembly is non-greaseable and pre-greased, no routine lubrication point is provided. After installation, perform a wheel alignment to confirm rear suspension geometry and tire tracking.

Quality Assurance

Delphi builds this assembly using OE-oriented design and validation methods, including dimensional and material analysis for fit consistency. Components are tested across extreme temperature ranges and salt-spray exposure to support durability in real-world suspension service.
