Federal-Mogul has introduced its Moog Problem Solver front lower ball joint for 2000-2005 Lincoln LS sedans. The new part (p/n K500084, model years 2000-2001; K500085, model years 2002-2005) eliminates the need for technicians to purchase and install a steering knuckle when replacing the OE front lower ball joint, the company reported. The ball joint has been specially equipped with a durable resin-plated housing to help prevent galvanic corrosion when mated with the aluminum steering knuckle, the maker added.
