You can Select Your Vehicle to check if 90389-18002 fits your vehicle.

All models are equipped with a two-piece bushing pressed into each spring eye, which should be inspected for cracks, damage, and looseness indicating excessive wear. To check for wear, jack up the frame until the weight is removed from the spring bushing and pry the spring eye up-and-down to check for movement; considerable movement indicates a worn bushing that should be replaced. For spring removal, it is recommended to work on one side at a time to maintain axle control and use the other side as a guide for reassembly. Begin by loosening the front or rear wheel lug nuts, raising the vehicle, and securely supporting it on jackstands before removing the wheel. Position a floor jack under the axle and raise it just enough to support the axle. Remove the lower shock mounting bolts and move the shock absorber aside. Unscrew the U-bolt nuts, then remove the spring tie plate and U-bolts from the axle. Next, remove the spring-to-shackle bolt and the spring eye-to-frame bracket bolt, then take the spring out of the vehicle. The leaf spring bushings can be removed by inserting a screwdriver into the inner diameter of the bushing half and pushing outward; if they won't loosen due to dirt and rust, apply penetrating oil and let it soak. Coat the inside of the spring eye with a thin layer of chassis grease and press the new bushing into position. Installation is the reverse of removal, ensuring that the spring mounting bolts and U-bolt nuts are tightened to the specified torque, with the vehicle sitting at normal ride height before tightening the front and rear mounting bolts.
