Description

Keep the front suspension located and the steering tight with the MOOG K6663 Front Lower Suspension Ball Joint. This front lower ball joint pivots the steering knuckle against the control arm, letting the wheel steer and travel while the suspension moves. It drops in as a direct-fit replacement for the 2004-2007 Buick Rainier, 2003-2006 Chevrolet SSR, 2002-2009 Chevrolet Trailblazer, 2002-2006 Chevrolet Trailblazer EXT, 2002-2009 GMC Envoy, 2002-2006 GMC Envoy XL, 2004-2005 GMC Envoy XUV, 2003-2008 Isuzu Ascender, 2002-2004 Oldsmobile Bravada, and 2005-2009 Saab 9-7X — see the Buyer's Guide tab for the full list.

Gusher Bearing design: Metal-to-metal bearing lets grease flow across the bearing surface for reduced friction.
Greaseable socket: Allows fresh lubricant to flush contaminants, helping reduce corrosion and wear.
Heat-treated ball stud: Treated to match or exceed OE requirements to improve fatigue strength.
Pre-installed dust boot: Premium boot shields the socket components from dirt and water.

A Belleville preload washer helps keep the bearing package tight as bearings wear, and heavy-duty gauge steel construction adds strength. Designed for OE fit and function with precision tolerances for straightforward installation. Replacing a worn ball joint helps restore vehicle handling.
