Delphi TC4611 Suspension Control Arm and Ball Joint Assembly - Front Left Lower

OE-Style Front Left Lower Control Arm

Delphi TC4611 is a front left lower suspension control arm and ball joint assembly built for direct replacement service on select Toyota and Lexus applications. It combines a stamped steel arm, pre-greased ball joint, and rubber bushings to support stable steering response and consistent suspension geometry.

Compatible With 2018-2023 Toyota Camry, 2019-2022 Toyota Avalon, 2019-2023 Lexus ES300h, 2020-2023 Lexus ES350, and 2021-2023 Lexus ES250 in the front left lower position.

• Stamped steel control arm with painted finish
• Pre-greased ball joint included
• Rubber bushings and rubber dust boot included
• Ball joint uses a bolt-in mounting type with threaded stud
• Castle nut and cotter pin included
• Standard replacement grade for OE-style service
• Black control arm, bushings, and boot components

Built For OE Replacement Service

Delphi TC4611 is engineered as a direct-fit suspension control arm assembly for the front left lower location. Delphi applies OE-focused dimensional and material analysis to help maintain proper fit between the replacement part and the original suspension layout. The assembly is tested for temperature extremes below -40 degrees C and above 120 degrees C, and it is exposed to 720 hours of salt spray to evaluate durability in demanding conditions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Part Helps Address

• Front-end clunking or looseness from a worn lower control arm assembly
• Uneven tire wear caused by suspension geometry changes
• Steering wander or reduced directional stability
• Noise from deteriorated bushings or a worn ball joint
• Restoring proper front left lower suspension support on Toyota Camry, Avalon, and Lexus ES models

Installation Notes

Verify vehicle fitment by year, make, model, and front left lower position before installation. This assembly is not adjustable and is not greaseable. Mounting hardware is not included, so confirm whether additional fasteners are needed for your application. Because the ball joint is pre-greased and supplied with a dust boot, installation should focus on correct alignment of the arm, bushings, and stud connection during service.

Quality Assurance

Delphi uses OE-based engineering and validation methods for its steering and suspension portfolio. TC4611 is built with stamped steel construction, rubber isolation components, and corrosion testing protocols intended to support consistent aftermarket replacement performance on the listed Toyota and Lexus applications.
