Installation Notes

Confirm the vehicle year, make, model, and steering position before ordering. For this part, use the application data to verify front or left placement where listed, since position can vary by vehicle. Inspect the steering rack, tie rod ends, and surrounding seals during service so the replacement bellows is installed on a clean, damage-free assembly.

Quality Assurance

Delphi applies OE steering expertise to its aftermarket parts and validates this bellows kit through extreme temperature and corrosion testing. The part is engineered using dimensional and material analysis to support proper OE-to-aftermarket fit and consistent steering-system protection.
