Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, mechanic's stethoscope.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported before working.

2. Inspect and Replace Struts/Shocks

Sub-steps:
1. Lift the vehicle using a jack and place it on jack stands.
2. Remove the wheel to access the strut assembly.
3. Inspect the strut for leaks and damage; if damaged, proceed to replace.
4. Remove the strut mounting bolts and detach the strut from the assembly.
5. Install the new strut and torque the bolts to the manufacturer’s specifications (typically around 30-40 ft-lbs).
6. Reinstall the wheel and lower the vehicle.

3. Replace Suspension Bushings

Sub-steps:
1. Remove the affected suspension component (control arm or sway bar) to access the bushings.
2. Carefully pry out the old bushings using a bushing removal tool.
3. Clean the mounting surfaces and install new bushings, applying grease as needed.
4. Reattach the suspension component and torque to specification.

4. Replace Sway Bar Links

Sub-steps:
1. Identify the sway bar links and remove the retaining nuts.
2. Detach the old sway bar link and inspect surrounding components.
3. Install the new sway bar link, ensuring proper orientation.
4. Torque the sway bar link nuts to manufacturer specifications (typically around 15-25 ft-lbs).
