Caution! When removing the rear suspension spring, it is necessary to use a special tool to compress the spring and hold it in this position while removing the spring.
Removal
1. Raise the rear of the vehicle and secure it on stands. Remove the corresponding rear wheel.
2. Using a special device, compress the spring so that it moves away from the top. When using a special device for compressing springs, make sure that the spring coils are firmly grasped and compress the spring from opposite sides. The spring has a very high compression force, so use only a very reliable tool. Never tie the spring with wire.
3. Unscrew the screws and remove the protective cover from the base of the lower rear suspension arm. Support the lower rear suspension arm with a jack through a wooden block.
4. Remove the nut and pivot bolt that secures the rear lower control arm to the rear subframe. Also remove the nut and pivot bolt that secures the stabilizer bar link to the lower control arm.
5. Carefully lower the rear lower control arm enough to allow the spring and upper plate to be removed.
6. Inspect the coil spring and upper support cup for signs of wear, damage or corrosion and replace if necessary.
Installation
1. Check and, if necessary, clean the lower spring support cup, then install the spring with the upper cup in place.
