Lexus 48231-0E030 Spring, Coil, Rear

Before raising the vehicle, measure the distance from the ground to the bottom of the rear suspension arm and record the measurement. Loosen the rear wheel lug nuts, then raise the rear of the vehicle and support it securely on jackstands before removing the rear wheels. Remove the fasteners and shield of the rear suspension arm plastic shield, if equipped. Disconnect the rear stabilizer bar link from the suspension arm. Using paint or a permanent marker, mark the position of the adjuster cams on the rear suspension arm for accurate reinstallation, then loosen the inside bolt and nut. Place a floor jack with a wooden block under the rear suspension arm below the coil spring pocket and raise the arm approximately 1 inch. Remove the lower arm-to-rear axle carrier (outer) bolt and slowly lower the rear suspension arm until the coil spring can be safely removed. Check and replace, if necessary, the coil spring upper and lower insulators. Set the coil spring into the rear suspension arm with the identifying mark facing outwards, then place the floor jack and wooden block under the rear suspension arm and begin to raise the arm until the top of the spring is seated against the upper insulator and rear subframe. Install the lower arm-to-axle carrier (outer) bolt and nut. Using the floor jack, raise the rear suspension arm to simulate the ride height measured earlier. Tighten the lower suspension arm nuts and bolts to the specified torque, ensuring the adjuster cams are in their original locations before tightening. Install the rear stabilizer bar link and tighten the nut to the specified torque. Finally, install the rear wheels and tighten the lug nuts to the specified torque, and consider having the rear alignment checked and adjusted if necessary.

The first step is to remove the strut and spring assembly as outlined in Section 3 (front) or Section 10 (rear). Then, mount the strut assembly in a vise, ensuring to line the vise jaws with wood or rags to prevent damage, and avoid tightening the vise excessively.
