We highly recommend using fresh Toyota hardware, including lower ball joint bolts and caliper bolts, with any spindle installation. This helps ensure a seamless process and provides peace of mind by reducing the risk of hardware failures, which can be both costly and dangerous. For added security, apply a dab of blue Loctite and torque the bolts to the specified settings. With the included hardware, you'll be ready to go.
