Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle at the designated jacking points.
Secure the vehicle with jack stands for safety.

3. Inspect Suspension Components

Sub-step 1: Check the strut mounts for any cracks or wear.
Sub-step 2: Tighten or replace any loose bolts on the struts and sway bar links.
Sub-step 3: If shocks are leaking or not functioning properly, proceed to replace them.

4. Replace Shock Absorbers (if necessary)

Sub-step 1: Remove the wheel to access the shock absorber.
Sub-step 2: Unbolt the top and bottom of the shock absorber using the appropriate socket.
Sub-step 3: Install the new shock absorber and torque bolts to the manufacturer's specifications (typically around 35-45 ft-lbs).
Sub-step 4: Reinstall the wheel and lower the vehicle.

5. Address Other Suspension Components

If control arms or bushings are worn, replace them:
- Sub-step 1: Remove the wheel and locate the control arm.
- Sub-step 2: Unbolt the control arm from the frame and the knuckle.
- Sub-step 3: Install the new control arm, ensuring bushings are properly seated.
- Sub-step 4: Torque all bolts to the specified settings.
