Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface, and secure it with wheel chocks.
Raise the vehicle using a jack and secure it on jack stands.

2. Inspect and Replace Suspension Components

a. Inspect Struts and Shocks

Tools Required: Socket set, torque wrench
Remove the wheel to access the struts/shocks.
Inspect for leaks or damage on the strut/shock absorber.
If damaged, proceed to replace the struts/shocks.

b. Replace Worn Bushings or Control Arms

Tools Required: Socket set, pry bar, torque wrench
Inspect control arms and bushings for wear.
If damaged, remove the control arm by unbolting it from the chassis and wheel hub.
Replace bushings if necessary and install new control arms, tightening to manufacturer specifications.

c. Replace Sway Bar Links and Bushings

Tools Required: Wrench set, torque wrench
Remove the sway bar link by unbolting it from the sway bar and control arm.
Install new sway bar links and bushings, tightening them to the specified torque.

3. Reassemble and Lower the Vehicle

Reinstall the wheel and tighten lug nuts to the manufacturer’s torque specification.
Remove jack stands and lower the vehicle back to the ground.
