Detailed Description

Delphi TC4268 is engineered as a front upper suspension ball joint for Toyota Tacoma, Toyota 4Runner, Toyota Tundra, and Toyota Sequoia applications. It uses a press-in mounting style, a tapered stud, and a rubber dust boot to support secure installation and long-term joint protection. The unit is pre-greased and supplied as a complete ball joint assembly with a castle nut, cotter pin, cotter pin hole, and mounting hardware included.

Delphi applies OE-level dimensional and material analysis to help ensure proper interchange with the original part. The part number TC4268 is also referenced in aftermarket cross listings for the same application, including MOOG Chassis Products K90255 and Mevotech Supreme MK90255.

Common Repair Applications

• Front-end looseness or play in the upper suspension joint
• Clunking or popping from the front suspension over bumps
• Uneven tire wear related to worn steering and suspension components
• Steering wander or reduced front-end stability
• Service replacement for a worn press-in upper ball joint

Installation Notes

Verify vehicle year, model, and front upper position before installation. This part uses a counterclockwise (left) thread direction and a press-in mounting design, so proper suspension service tools are required. Inspect the control arm, surrounding hardware, and alignment settings during replacement. After installation, a professional wheel alignment is recommended.

Quality Assurance

Delphi tests steering and suspension components under extreme temperature and corrosion conditions, including sub-zero and high-heat exposure plus extended salt spray testing. That validation supports OE-style durability for front suspension service on Toyota Tacoma, Toyota 4Runner, Toyota Tundra, and Toyota Sequoia applications.
