Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the vehicle and support it with jack stands.

2. Inspect and Replace Suspension Components

Check Shocks/Struts:
- Remove the wheel to access the suspension components.
- Inspect shocks/struts for leaks or physical damage.
- If defective, proceed with the next step to replace.
Remove and Replace:
- Use a socket set to remove the bolts securing the struts to the vehicle.
- Disconnect any electrical connectors if applicable.
- Install new struts by reversing the removal process, ensuring to torque bolts to manufacturer specifications (typically around 50-70 ft-lbs).

3. Inspect and Replace Sway Bar Links and Bushings

Check Links:
- Inspect sway bar links for looseness or damage.
- Remove the links using a wrench and socket.
- Replace with new sway bar links and torque to specifications (usually around 30-40 ft-lbs).
Replace Bushings:
- Remove the old bushings from the sway bar.
- Install new bushings and ensure they are seated properly.

4. Inspect Ball Joints and Control Arms

Check for Play:
- Use a pry bar to check for excess movement in the ball joints and control arms.
- If any play is detected, replace the worn components.
- Follow the manufacturer's specifications for torque when reinstalling.
