Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Inspect and Replace Shock Absorbers

Sub-steps:
1. Remove the rear wheels using a socket set.
2. Locate the rear shock absorber mounting bolts and remove them.
3. Pull the shock absorber out of its mounting.
4. Install the new shock absorber in the reverse order of removal.
5. Torque the mounting bolts to the manufacturer's specifications (usually around 35-45 ft-lbs).

3. Inspect and Replace Suspension Bushings

Sub-steps:
1. Use a wrench to remove any bolts securing the control arms.
2. Remove the control arm from the vehicle.
3. Press out the old bushings using a bushing tool.
4. Install new bushings and reattach the control arm, ensuring all bolts are torqued to specifications.

4. Inspect and Replace Springs

Sub-steps:
1. Use a spring compressor to safely compress the rear coil springs.
2. Remove the spring from its mount.
3. Install the new spring, ensuring it is seated correctly in its mounts and decompress the spring compressor.

5. Check Wheel Alignment

Sub-steps:
1. After replacing components, use an alignment tool to check rear wheel alignment.
2. Adjust as necessary to bring the alignment back to manufacturer specifications.
