Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Safety warning: Ensure the vehicle is securely supported on jack stands if lifted.

2. Inspect and Replace Worn Components

Inspect Bushings:
- Remove any undercarriage covers if necessary.
- Visually check for cracks or excessive wear on control arm bushings and sway bar bushings.
Replace Damaged Bushings:
- Use a bushing removal tool to remove worn bushings from the control arm.
- Clean the control arm before installing new bushings.
- Install new bushings using a bushing press, ensuring they are seated properly.

3. Check and Replace Shock Absorbers

Test Shock Absorbers:
- Perform a bounce test: push down on the front or rear of the car and release; the vehicle should return to its original position without excessive bouncing.
Replace if Necessary:
- Remove the wheel for access.
- Unbolt the top and bottom mounts of the shock absorber.
- Replace with a new shock absorber, tightening to manufacturer specifications (usually around 15-20 ft-lbs for top mounts and 50-70 ft-lbs for bottom mounts).

4. Tighten Suspension Components

Torque Suspension Bolts:
- Inspect all accessible bolts in the suspension system.
- Use a torque wrench to tighten to the specified torque values (refer to the service manual for specific values).
