Solution

1. Preparation

Tools Required: Jack stands, socket set, torque wrench, pry bar, flashlight.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during the inspection.

2. Inspect Front Suspension

Lift the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the lower control arms, upper control arms, and bushings for any signs of cracks or wear.
Use a pry bar to check for play in the ball joints; if any movement is detected, they may need replacement.

3. Check Sway Bar Links

Locate the sway bar links and examine them for damage or looseness.
Tighten any loose bolts to the manufacturer's specifications.
If the links are damaged or excessively worn, replace them with new components.

4. Examine CV Joints and Axles

Inspect the CV boots for any tears or grease leakage.
Move the axles up and down while observing the CV joints; any clicking or popping indicates they may need to be replaced.
If necessary, replace the faulty CV joints or axles, ensuring to torque all bolts to the specified values.

5. Reassemble and Lower Vehicle

Reinstall any components removed during inspection.
Lower the vehicle and reconnect the battery.
Ensure all fasteners are tightened to the manufacturer's specifications.
