Solution

1. Preparation

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

2. Replace Worn Shocks/Struts

Lift Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
Remove Wheels: Use a lug wrench to remove the wheels for access to the suspension components.
Disconnect Old Shocks/Struts:
- Locate the mounting bolts for the shocks/struts.
- Use a socket set to remove the top and bottom mounting bolts.
- Carefully detach the shock/strut from its mount.
Install New Shocks/Struts:
- Position the new shock/strut in place.
- Reattach and tighten the mounting bolts to the manufacturer’s torque specifications (generally 30-50 ft-lbs but check specific values).
Reinstall Wheels: Put the wheels back on and hand-tighten the lug nuts.

3. Check and Replace Bushings

Inspect Bushings: Look for cracks or signs of deterioration in the control arm bushings.
Remove Control Arm:
- If necessary, remove the bolts securing the control arm using a socket set.
- Replace the bushings with new ones by pressing them out and in using a bushing tool.
Reattach Control Arm: Reinstall the control arm and secure it with the appropriate torque.

4. Realign Suspension

After all repairs, take the vehicle to a professional alignment shop to ensure proper alignment settings.
