Delphi TC203 Suspension Ball Joint - Front Upper

Delphi TC203 Suspension Ball Joint

Delphi TC203 is a bolt-on suspension ball joint built for OE-style service on vehicles that use a threaded stud and tapered fitment. It combines a steel body, black finish, and dust boot protection with Delphi’s dimensional and material analysis for consistent aftermarket fit.

Key Features

• Steel suspension ball joint assembly with black finish
• Bolt-on mounting type with 3 mounting holes
• Threaded stud with tapered ends for secure suspension connection
• Dust boot included; chloroprene rubber (CR) boot material
• Mounting hardware, bolts, washers, and nuts included
• Standard suspension grade type; non-greaseable design
• Stud thread diameter: 14.0 mm; wrench size: 22.0 mm
• Part number TC203 for catalog and service reference

Detailed Description

Delphi TC203 is engineered for suspension service where precise fit and OE-style geometry matter. The assembly is designed with a 14.0 mm threaded stud, tapered stud ends, and a bolt-on mounting pattern with three holes and 36.5 mm between mounting holes. Delphi subjects its steering and suspension components to extreme temperature and salt-spray testing, helping verify durability in harsh road conditions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

For fitment-based searches, Delphi TC203 is the type of suspension ball joint used when replacing worn front-end components on vehicles such as Honda Civic and related applications that call for this OE-style design. If you are searching by part number TC203, this listing provides the core dimensions and mounting details needed to confirm application match before installation.

What It Helps Fix

• Front suspension looseness or play at the ball joint
• Clunking or knocking from worn steering and suspension joints
• Uneven tire wear caused by excessive joint movement
• Steering wander or reduced directional stability
• Boot damage that can expose the joint to contamination

Installation Notes

Confirm stud diameter, taper, mounting-hole spacing, and overall dimensions against the original part before installation. The TC203 uses a bolt-on mounting style and includes the required mounting bolts, washers, and nuts; it does not use a grease fitting, so no periodic greasing is required. Always torque fasteners to the vehicle manufacturer’s specification and inspect adjacent suspension components for wear during service.

Quality Assurance

Delphi applies OE-focused engineering to its aftermarket steering and suspension portfolio, with dimensional and material analysis used to support part-to-part compatibility. The TC203 is tested for temperature extremes and salt-spray exposure to help validate durability in demanding operating conditions.
