Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Remove the wheels for better access to the suspension components.

3. Inspect and Replace Shock Absorbers or Struts

Sub-step 1: Locate the shock absorbers or struts on the front and rear suspension.
Sub-step 2: Remove any bolts or nuts securing the shocks/struts using a socket set.
Sub-step 3: Carefully detach the shock or strut from the mounting points.
Sub-step 4: Compare the old shock/strut with the new one to ensure proper fit.
Sub-step 5: Install the new shock or strut, tightening bolts to the manufacturer's specified torque settings (typically 30-50 ft-lbs).

4. Inspect and Replace Suspension Bushings

Sub-step 1: Identify any worn or cracked bushings in the control arms or sway bars.
Sub-step 2: Use a bushing removal tool to detach the old bushings.
Sub-step 3: Install new bushings, ensuring they are seated properly.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and lower the vehicle off the jack stands.
Perform a final torque check on the wheel bolts.
