OE-Style Rear Left Upper Control Arm
Delphi TC3771 is a suspension control arm and ball joint assembly built for the rear left upper position on select Kia Sedona and Hyundai Entourage applications. It combines a stamped steel arm with a pre-greased ball joint, rubber bushings, and a dust boot to support precise rear suspension movement and consistent steering response in power-steering-equipped vehicles.
Key Features
- Part number TC3771 for direct reference and ordering
- Fits 2006-2012 Kia Sedona, rear left upper
- Fits 2007-2008 Hyundai Entourage, rear left upper
- Stamped steel control arm with black finish
- Ball joint included with press-in mounting type
- Pre-greased design with bushings included
- Dust boot included with chloroprene rubber construction
- Mounting hardware and locking nut included
- Premium grade replacement for OE-style suspension service
Detailed Description
Delphi TC3771 is engineered as a rear left upper suspension control arm and ball joint assembly for the Kia Sedona and Hyundai Entourage. The stamped steel arm uses rubber bushings and a press-in ball joint design to match the original suspension layout, while the threaded ball joint stud and included locking nut support secure installation. Delphi applies dimensional and material analysis to help maintain OE-level fitment compatibility, and the part is tested across extreme temperatures and salt-spray exposure to evaluate durability in demanding conditions. If you are replacing a worn rear upper control arm on a 2014 Kia Sedona or 2006-2012 Kia Sedona, this assembly provides a direct-service solution. It also serves 2007-2008 Hyundai Entourage rear left upper applications. This part cross-references Dorman - OE Solutions 521-049 for the same application.
Common Problems This Part Can Address
- Rear suspension clunking or knocking from worn bushings or ball joint wear
- Excessive rear wheel movement caused by a fatigued control arm
- Uneven tire wear related to suspension looseness
- Loose or unstable rear-end handling over bumps and turns
- Corrosion-related replacement needs on the original arm assembly
Installation Notes and Tips
Install TC3771 at the rear left upper position only. Verify the threaded stud direction, bushing dimensions, and mounting points before installation, and torque all fasteners to the vehicle manufacturer’s specifications. Because the ball joint is pre-greased and not greaseable, no routine lubrication is required after installation. A professional alignment is recommended after suspension component replacement.
Quality Assurance
Delphi builds this suspension control arm and ball joint assembly using OE-focused engineering practices, including temperature cycling and extended salt-spray testing. The brand’s aftermarket steering and suspension portfolio is developed from OE expertise to support fit and material consistency across the listed Kia Sedona and Hyundai Entourage applications.
