Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect Suspension Components

Tools Required: Socket set, torque wrench, pry bar.
Visually inspect control arms, ball joints, and bushings for signs of wear or damage.
Use a pry bar to check for excessive play in the ball joints.
If any components are damaged, they will need to be replaced.

3. Check Power Steering System

Tools Required: Fluid syringe or funnel, rags.
Remove the power steering fluid reservoir cap and check the fluid level.
If low, top off with the recommended power steering fluid (consult the owner's manual).
Inspect the hoses for leaks.

Tools Required: Wrench set, flashlight.
Inspect the tie rod ends and rack and pinion for play or damage.
Tighten any loose bolts to manufacturer specifications.
Replace any worn or damaged parts as necessary.

5. Inspect CV Joints and Boots

Tools Required: Jack and jack stands, socket set.
Lift the front of the vehicle and secure it on jack stands.
Inspect the CV joints for cracks or tearing in the boots.
If the boots are damaged or if the CV joint shows signs of wear, replace the CV axle.
