It is a direct-fit replacement for many vehicles, among them the 2019-2025 Toyota RAV4, 2023 Toyota bZ4X and 2023 Toyota Crown. See the "Vehicles it fits" section for the full list and engine details.
MOOG backs its ball joints with quality materials and thorough testing for dependable performance. Its problem-solving features are designed to make installation quick and straightforward.
- Problem Solver® Gusher Bearing: A metal-to-metal design adds strength and lets grease flow across the bearing surface for reduced friction and long life.
- Heat-treated ball studs: Heat treated to match or exceed OE requirements, helping inhibit premature failure and improve fatigue strength.
- Greaseable socket and pre-installed dust boot: New lubricant can be added to flush out contaminants and reduce corrosion and wear. The boot shields the socket components from dirt and water.
- Belleville preload washer and patented pressed-in cover plate: The washer absorbs impact and helps keep the bearing package tight as the bearings wear. The cover plate seals out debris and minimizes looseness to reduce bearing wear.
Precision tolerances are intended for easy installation and steering alignment. MOOG draws on 50+ dedicated engineers and 50+ patents, and it engineers every part with purpose. Signs a lower ball joint may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear, and a torn boot. Inspect the suspension to confirm the cause before replacing.
