Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a flat surface and the engine is off.
Raise the vehicle using a jack and securely support it with jack stands.

2. Inspect and Replace Suspension Components

2.1. Inspect Suspension Components

Visually inspect the struts, shocks, and all bushings for signs of wear or damage.
Use a pry bar to check for play in control arms and bushings.

2.2. Replace Worn or Damaged Components

Tools Required: Socket set, torque wrench, pry bar, jack stands.
Remove the damaged component (e.g., strut, sway bar link).
- Use a socket to remove the bolts securing the component.
- Carefully detach the component from the suspension.
Install the new component.
- Align the new part into position.
- Hand-tighten the bolts, then use a torque wrench to tighten them to the manufacturer's specifications.
Repeat for all identified components needing replacement.

3. Reassemble and Lower Vehicle

Ensure all tools are removed from the work area.
Carefully lower the vehicle back to the ground.
Recheck the torque on all bolts after lowering the vehicle.
