Solution

1. Preparation

Gather tools: socket set, torque wrench, jack, jack stands, and pry bar.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety Warning: Always engage the parking brake and use wheel chocks.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure it with jack stands to ensure safety while working underneath.

3. Inspect and Replace Suspension Components

A. Control Arms and Bushings

Remove the bolts securing the control arms to the chassis and the wheel hub.
Inspect the bushings for signs of cracking or excessive wear.
If damaged, replace the control arms or bushings as necessary.
Torque the control arm bolts to the manufacturer’s specifications (typically around 50-70 ft-lbs).

B. Strut Assembly

Remove the strut assembly by unbolting it from the upper strut mount and lower knuckle.
Inspect the strut for signs of leakage or damage.
If the strut is faulty, replace it with a new unit.
Reinstall the strut and tighten the fasteners to the specified torque (usually around 40-50 ft-lbs for upper mount, 60-80 ft-lbs for lower mount).

C. Sway Bar Links

Check the sway bar links for play or damage.
If they are worn, remove the bolts securing them to the sway bar and the strut.
Install new sway bar links and torque to manufacturer specifications.

4. Reassemble and Lower the Vehicle

Reinstall any components that were removed for inspection.
Ensure all bolts are tightened to the specified torque.
Remove jack stands and lower the vehicle back to the ground.
