Solution

1. Preparation

Gather tools and parts for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electronic suspension components.

2. Replace Shock Absorbers

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel on the side where the shock absorber will be replaced using a socket set.
Disconnect the shock absorber:
- Remove the bolts securing the shock absorber to the lower control arm.
- Remove the upper mounting bolts from the vehicle body.
Install the new shock absorber:
- Position the new shock absorber in place and secure the upper mounting bolts.
- Reattach the lower bolts to the control arm and torque them to the manufacturer's specifications (typically around 50-70 lb-ft).
Reinstall the wheel and lower the vehicle back to the ground.

3. Inspect and Replace Springs (if necessary)

Remove the wheel as outlined in step 1 of the previous section.
Remove the shock absorber as detailed in step 3 of the previous section.
Inspect the coil spring for cracks or deformation. If damaged, proceed to replace:
- Use a spring compressor to safely compress the coil spring.
- Remove the retaining clips and carefully take out the spring.
- Install the new spring, ensuring it is positioned correctly.
- Remove the spring compressor once the spring is secured.
