Keep steering tight and suspension movement controlled with the MOOG Chassis Front Lower Suspension Ball Joint K5301. It installs as a direct-fit replacement for the front lower position on the 1988-1996 Buick Regal, 1990-2001 Chevrolet Lumina, 1995-1999 Chevrolet Monte Carlo, 1988-1997 Oldsmobile Cutlass Supreme, and 1988-1996 Pontiac Grand Prix — see the Buyer's Guide tab for engine-level details.
Gusher Bearing design: a metal-to-metal bearing lets grease flow through the bearing surface to reduce friction and support long life.
Greaseable socket: the part can be re-greased to help flush contaminants and debris from the bearing package.
Belleville preload washer: helps keep the bearing package tight as the internal bearings wear.
Heat-treated ball stud: heat treated to match or exceed OE requirements to help inhibit premature failure and improve fatigue strength.
A premium boot helps keep out contaminants, while a pressed-in cover plate seals against debris to minimize looseness. The joint is coated for corrosion resistance and built with heavy-duty gauge steel for strength and durability. Designed for OE fit and function, this ball joint replaces a worn original; if a failing front lower ball joint is the cause of clunking over bumps or when turning, loose steering, or uneven tire wear, replacing it helps restore proper handling.
