Silence a clunking, vibrating front corner with the KYB strut mount kit (SM5804), a direct-fit suspension strut mount kit that drops in for the 2011-2020 Toyota Sienna. This front assembly pairs the mount with its bearing plate — the plate serves as the steering pivot and helps support vehicle weight, making it critical to steering feel and wheel alignment.
KYB strut mounts are designed to reduce the noise, harshness and jarring that old, hardened rubber insulators transmit into the cabin, cushioning impacts from road bumps.
- Superior rubber: helps reduce noise, vibration and harshness.
- Mount bearing: supports smoother steering and helps retain front-end alignment.
- OE-quality build: replacement components designed for each application.
- Matched grade studs and nuts: included for a secure, correct-torque installation.
If worn, hardened, or noisy front strut mounts are the cause of your vibration, ride harshness, or steering-related noise, this kit replaces them on the listed application.
