OE-Style Construction

Delphi TC4408 is engineered for the front left lower position on the Mazda CX-5 and uses a stamped steel arm for consistent fit and serviceability. The assembly includes the ball joint, bushings, and dust boot, with a pre-greased design and non-greaseable construction for straightforward replacement service. Delphi subjects its steering and suspension parts to extreme temperature and salt-spray testing, and uses dimensional and material analysis to help maintain OE-level compatibility.

This part cross-references MOOG Chassis Products RK623703 for the same application.

Common Replacement Reasons

• Clunking or knocking from the front suspension
• Excessive play in the front left lower control arm
• Uneven tire wear caused by worn suspension joints or bushings
• Steering pull or unstable road feel on Mazda CX-5 models
• Cracked bushings, damaged dust boot, or worn ball joint movement

Installation Notes

Replace this assembly on the front left lower corner of the Mazda CX-5 and verify alignment after installation. Because the ball joint uses a press-in mounting type and pinch-style stud, confirm the knuckle and mounting points are clean and in good condition before assembly. Mounting hardware is not included, so reuse or source the required fasteners as needed.

Quality Assurance

Delphi applies OE-focused engineering and durability testing to its aftermarket steering and suspension portfolio. TC4408 is tested across extreme temperature ranges and extended salt-spray exposure to support long-term corrosion resistance and fit consistency for Mazda CX-5 front suspension service.
