Ball Joint Checking

WARNING: This page is about a different car, the 2003 Ford Windstar and 2002 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Prior to inspecting ball joints, it is necessary to inspect wheel bearings. See WHEEL BEARINGS .

With vehicle raised, position safety stand beneath lower control arm to be tested. While assistant pulls and pushes the top and bottom of the tire, watch for movement between lower end of knuckle and control arm. Movement indicates ball joint wear. If ball joint is perceptibly loose, replace lower control arm assembly. See LOWER CONTROL ARM under REMOVAL & INSTALLATION.
