Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if electrical components are involved.

2. Inspect and Replace Shock Absorbers

Sub-steps:
- Lift the vehicle using a jack and secure it on jack stands.
- Remove the wheels to access the shock absorbers.
- Inspect the shock absorbers for leaks, dents, or corrosion.
- If defective, unbolt the top and bottom mounts of the shock absorber.
- Replace with new shock absorbers, ensuring proper alignment of the mounting holes.
- Torque the bolts to the manufacturer’s specifications (typically around 30-40 lb-ft for top and bottom mounts).

3. Check and Replace Suspension Bushings

Sub-steps:
- Inspect all suspension bushings for cracks or excessive wear.
- If worn, remove the affected suspension component (e.g., control arm) to access the bushings.
- Use a bushing removal tool to extract old bushings and install new ones.
- Reassemble the suspension component and torque bolts to manufacturer's specifications.

4. Wheel Alignment

Sub-steps:
- After replacing shocks and bushings, ensure the vehicle is on a level surface.
- Measure and adjust the alignment angles (camber, caster, toe) according to the specifications using an alignment machine.
- Test drive the vehicle to confirm proper handling.
