Delphi applies its OE steering expertise to this aftermarket assembly, with extensive dimensional and material analysis for close OE-to-aftermarket compatibility.
The arm locates the wheel while the integrated ball joint lets the steering knuckle pivot and travel with the suspension. If a worn arm or joint is the cause of loose steering or a front-end clunk, this assembly replaces both in one piece.
