Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, safety glasses
Safely elevate the vehicle using a jack and secure it on jack stands.
Remove the wheel corresponding to the affected side for better access to suspension components.

2. Inspect and Replace Struts/Shocks

Sub-steps:
1. Disconnect the upper and lower mounting bolts of the strut using a socket set.
2. Remove the strut assembly from the vehicle.
3. Inspect for leaks or damage on the strut; replace if necessary.
4. Install the new strut by reversing the removal process, ensuring to torque the bolts to the manufacturer specifications (typically around 50-60 ft-lbs for strut bolts).
5. Repeat for the opposite side if required.

3. Replace Sway Bar Links/Bushings

Sub-steps:
1. Locate the sway bar links and inspect for any damage or detachment.
2. Remove the nuts securing the sway bar links using a socket set.
3. Replace any damaged sway bar links and bushings with new parts.
4. Reinstall by tightening to manufacturer specifications (usually around 30-40 ft-lbs).

4. Check and Replace Control Arm Bushings

Sub-steps:
1. Use a pry bar to check for play in the control arm bushings.
2. If excessive movement is detected, remove the control arm by undoing the mounting bolts.
3. Replace worn bushings with new ones using a bushing press.
4. Reinstall the control arm and torque the bolts to manufacturer specifications.
