Detailed Description

This Delphi suspension control arm and ball joint assembly is engineered for the front right lower position on the Mazda CX-5. The stamped steel construction provides a factory-style structure, while the included ball joint, bushings, and dust boot simplify replacement of a worn front suspension assembly. Delphi TC4409 is also cross-referenced to MOOG Chassis Products RK623704 for the same application.

Compatible With 2017-2024 Mazda CX-5, front right lower. Use TC4409 when replacing a worn lower control arm assembly on the Mazda CX-5 and when restoring proper front suspension geometry and steering response.

What It Helps Address

• Front-end clunking or knocking from a worn control arm assembly
• Excessive play from deteriorated bushings or ball joint wear
• Uneven tire wear caused by suspension looseness
• Steering pull or unstable road feel from front suspension wear
• Inspection failure related to damaged lower control arm components

Installation Notes and Tips

Install TC4409 at the front right lower position only. Because the ball joint is press-in and the stud uses a pinch-style connection, proper suspension tools and torque procedures are required. Verify alignment after installation, and inspect adjacent components such as the opposite control arm, tie rods, and strut hardware while the suspension is apart.

Quality Assurance

Delphi uses OE-oriented engineering and validation methods for its steering and suspension portfolio. This part is subjected to temperature extremes below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray testing, to support durability in real-world service.
