Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, and a flashlight.
Ensure the vehicle is on a flat surface, and engage the parking brake.

2. Inspect Steering Components

Remove the front wheels using a socket set.
Inspect the tie rods and steering rack for any signs of damage or excessive play.
Check all fasteners for tightness and torque to manufacturer specifications.

3. Check Wheel Bearings

While the wheel is off, grasp the hub and try to move it side to side.
If there is any play, the wheel bearings may need to be replaced.
If the bearings are faulty, proceed to remove the hub assembly as needed for replacement.

4. Evaluate CV Joints

Inspect the CV boots for tears or leaking grease.
If the boots are damaged, the CV joints may need to be replaced.
Remove the axle nut and disconnect the CV joint from the hub to replace it.

5. Inspect Suspension Components

Check the control arm bushings and struts for signs of wear or damage.
Replace any worn bushings with new ones, ensuring they are torqued to specification.
Reassemble any components that were removed during the inspection.
