Installation Notes and Tips
Install 339137 on the front left side only for the listed application. Follow Toyota service procedures for strut and coil spring assembly replacement, and inspect related suspension components during service. KYB recommends new strut mounts, part number SM5179, to reduce noise and vibration, and a KYB strut boot, part number SB101, to help protect the strut from dirt, debris, and salt.
