Built For OE Fit And Material Match

Delphi applies OE engineering practices to its aftermarket steering and suspension portfolio, and TC1515 reflects that approach with careful dimensional and material analysis. The ball joint uses a steel body, a chloroprene rubber dust boot, and a tapered threaded stud to support secure installation in the front right lower suspension position. This part cross-references MOOG Chassis Products K90347 and Dorman - OE Solutions 524-154 for the same application.

Common Repair Symptoms

• Front-end clunking or popping over bumps
• Loose or wandering steering feel
• Uneven tire wear from worn suspension joints
• Excessive play in the lower control arm connection
• Inspection failure from worn or damaged ball joint components

Installation Notes

Verify vehicle fitment by year, make, model, and front right lower position before installation. Inspect the surrounding suspension components, control arm mounting points, and fasteners for wear or damage during service. Because this is a bolt-on assembly with included hardware, installation is straightforward when the mounting surfaces are clean and the tapered stud seats correctly.

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 helps support OE-level durability expectations for daily driving and routine suspension repair.
