Detailed Description

Delphi TC4266 is a front lower suspension ball joint engineered for 2004-2008 Acura TL vehicles. It features a press-in design, tapered stud, threaded stud type, and standard replacement construction for service work that requires a direct-fit suspension component.

Delphi applies OE-level dimensional and material analysis to help maintain proper fit and compatibility with the original suspension layout. The part is tested for demanding temperature extremes and salt exposure, reflecting the brand’s focus on durability in real-world driving conditions. This part cross-references MOOG Chassis Products K500117 for the same application.

What This Part Helps Address

  • Front-end looseness or play from a worn lower ball joint
  • Clunking or popping noises from the front suspension
  • Uneven steering response during turning or braking
  • Suspension movement issues caused by worn joint surfaces
  • Restoration of proper front lower suspension geometry on Acura TL models

Installation Notes and Tips

Fits 2004-2008 Acura TL, front lower. Verify left-thread orientation, press-in mounting style, and stud taper before installation. Because this is a suspension ball joint, proper removal and pressing tools are recommended to avoid damage to the control arm or surrounding components. Confirm alignment after installation.
