Delphi TC5433 Suspension Control Arm - Front Left Lower

OE-Style Front Lower Control Arm

Delphi TC5433 is a standard replacement suspension control arm built for the front lower position on select Nissan Pathfinder and INFINITI QX4 applications. It uses stamped steel construction with rubber bushings to support stable suspension movement and consistent alignment geometry.

Built from OE-focused dimensional and material analysis, this Delphi control arm is made for drivers replacing worn front suspension components on a 1996-2004 Nissan Pathfinder or 1997-2003 INFINITI QX4. The TC5433 is a direct-fit style solution for front left lower service, with fitment also listed for front right lower use where specified by the vehicle application.

• Fits 1997-2003 INFINITI QX4, front left lower

Detailed Description

The Delphi TC5433 front lower control arm is engineered for suspension repair where worn bushings, looseness, or alignment instability have developed. Its stamped steel body and rubber bushing design help restore controlled wheel movement and maintain the suspension geometry expected in Nissan Pathfinder and INFINITI QX4 front-end service. Delphi applies OE-level dimensional and material analysis to improve part-to-vehicle consistency, and the component is tested for temperature extremes and salt-spray exposure to support durability in demanding conditions. This part cross-references MOOG Chassis Products RK640330 for the same application.

What It Helps Fix

• Front-end clunking or knocking from worn control arm bushings
• Loose or unstable steering feel during braking or cornering
• Uneven tire wear caused by suspension geometry issues
• Excessive play in the front lower suspension
• Alignment problems after control arm wear or failure

Installation Notes and Tips

Fits 1996-2004 Nissan Pathfinder, front left lower. Fits 1997-2003 INFINITI QX4, front left lower. Verify the vehicle’s exact position before ordering, since the application tab should be used to confirm side-specific fitment. Mounting hardware is not included. Because this is a bolt-in ball joint design, inspect related suspension wear items and perform a professional alignment after installation.

Quality Assurance

Delphi builds this control arm using OE-focused engineering practices and durability testing that includes extreme temperature exposure and extended salt-spray evaluation. The TC5433 is a standard replacement part intended to match the fit and material expectations of the original suspension component.
