Keep the front suspension tight and steering responsive with the MOOG K6539 Front Lower Suspension Ball Joint. It drops in as a direct-fit replacement for the 1999-2006 Chevrolet Silverado 1500 and GMC Sierra 1500, plus the 2007 Chevrolet Silverado 1500 Classic and 2007 GMC Sierra 1500 Classic — see the Buyer's Guide tab for engine-level fitment. Designed for OE fit and function, this greaseable joint locates the lower control arm to the steering knuckle while allowing the suspension to move and pivot.
Built with heavy-duty gauge steel construction for strength and durability, K6539 installs with precision tolerances for easier alignment. A worn ball joint may show up as clunking, loose steering, or uneven tire wear — if the joint is the cause, this replaces it and helps restore vehicle handling.
What vehicles does the MOOG K6539 fit?
It fits the 1999-2006 Chevrolet Silverado 1500 and GMC Sierra 1500, plus the 2007 Chevrolet Silverado 1500 Classic and 2007 GMC Sierra 1500 Classic. Check the Buyer's Guide tab for engine-level details.
What position is this ball joint?
K6539 is a front lower suspension ball joint. It connects the lower control arm to the steering knuckle on the listed applications.
Is this ball joint greaseable?
Yes. It has a greaseable socket, so new lubricant can flush out contaminants to reduce corrosion and wear, and its Gusher Bearing lets grease flow through the bearing surface.
What are signs my ball joint may need replacing?
Common signs include clunking over the front end, loose or wandering steering, and uneven tire wear. Have the cause diagnosed, since these symptoms can come from other worn parts too.
Does it come with a dust boot?
Yes, a premium dust boot is pre-installed to shield the socket components from dirt and water, and a Belleville preload washer helps keep the bearing package tight as the bearings wear.
