Keep your front suspension tight and your steering precise with the MOOG Front Upper Suspension Ball Joint K90255. This greaseable ball joint is a direct-fit replacement for the front upper position on the 1996-2002 Toyota 4Runner, 2001-2007 Toyota Sequoia, 1995-2004 Toyota Tacoma, and 2000-2006 Toyota Tundra — see the Buyer's Guide tab for engine-level fitment details.
Gusher Bearing design: a metal-to-metal bearing lets grease flow through the bearing surface to reduce friction and support long service life.
Greaseable socket: allows fresh lubricant to flush out contaminants, helping reduce corrosion and wear.
Heat-treated ball stud: the ball stud is heat treated to match or exceed OE requirements to inhibit premature failure and improve fatigue strength.
Premium boot & pressed-in cover plate: the boot keeps out contaminants and a Belleville preload washer helps keep the bearing package tight as bearings wear.
Built with heavy-duty gauge steel construction and designed for OE fit and function, this ball joint replacement helps restore vehicle handling. If a worn upper ball joint is behind clunking over bumps, wandering steering, or uneven tire wear, installing the K90255 replaces it. Ball joints wear as a pair — inspect and service both sides for balanced handling.
