Delphi TC5329 Suspension Control Arm and Ball Joint Assembly - Front Left Upper

Front Left Upper Control Arm for Hummer H3 and H3T

Delphi TC5329 is a front left upper suspension control arm and ball joint assembly built for OE-style replacement on select Hummer applications. It combines an aluminum control arm with a pre-greased ball joint, rubber bushings, and included mounting hardware for a direct-fit service part.

Key Features

• Fits 2006-2010 Hummer H3, front left upper
• Fits 2009-2010 Hummer H3T, front left upper
• OE-focused aftermarket design from Delphi
• Aluminum control arm construction with casting/forged design
• Pre-greased ball joint with machined mounting type
• Rubber bushings included
• Standard replacement grade for front suspension service
• Mounting hardware included
• Part number: TC5329

Detailed Description

Delphi TC5329 is engineered for the front left upper position and is built to match OE dimensional and material requirements for proper suspension geometry. The aluminum arm uses a machined, grooved-stud ball joint design and rubber bushings to support controlled movement and consistent front-end operation on the Hummer H3 and H3T. Delphi validates its steering and suspension components through extreme temperature and corrosion testing, including sub-zero and high-heat exposure plus extended salt spray testing, to help confirm durability in demanding road conditions. If you are replacing a worn front left upper control arm on a 2006-2010 Hummer H3 or 2009-2010 Hummer H3T, TC5329 provides a direct service solution. This part cross-references Dorman Premium CB91007PR for the same application.

What This Part Helps Address

• Front-end clunking or knocking from a worn upper control arm assembly
• Uneven tire wear caused by suspension geometry changes
• Loose or unstable steering feel from worn ball joint or bushings
• Excessive suspension play at the front left upper corner
• Inspection failure related to worn suspension components

Installation Notes and Tips

Install TC5329 in the front left upper position only and verify alignment after replacement. Inspect adjacent suspension components, fasteners, and steering parts before installation so the new control arm is not paired with worn hardware elsewhere in the front suspension. Because this assembly is pre-greased and not greaseable, no grease fitting is provided. Confirm vehicle year, model, and position against the fitment data before ordering.

Quality Assurance

Delphi applies OE engineering practices to its aftermarket steering and suspension portfolio. TC5329 is tested for temperature extremes and salt-spray exposure, and it is built using dimensional and material analysis to support OE-level fit and compatibility.
