Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect and Replace Rear Springs

Inspect Springs:
- Remove the rear wheels using a socket set.
- Visually inspect the rear coil springs for cracks, rust, or deformation.
Replace Springs:
- If springs are damaged, proceed to replace them:
  1. Use a spring compressor to safely compress the old springs.
  2. Remove the retaining bolts and take out the old springs.
  3. Install the new springs, ensuring they are seated correctly.
  4. Reinstall the retaining bolts to manufacturer torque specifications (typically around 40-45 ft-lbs).
  5. Release the spring compressor.

3. Inspect and Replace Shock Absorbers

Check Shocks:
- Inspect shock absorbers for leaks and physical damage.
Replace Shocks:
- If necessary:
  1. Remove the top bolts securing the shock to the mount.
  2. Remove the bottom bolts connecting the shock to the rear axle.
  3. Install new shocks in reverse order of removal, tightening to manufacturer specifications (usually around 30-35 ft-lbs on top and bottom).

4. Alignment Check

After replacing the springs and shocks, have the vehicle's alignment checked and adjusted by a professional to ensure proper handling and tire wear.
