Solution

1. Preparation

Gather tools such as a jack, jack stands, socket set, and a torque wrench.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to avoid any electrical issues while working on the vehicle.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir and check the fluid level.
If the fluid is low, top it off with the recommended power steering fluid.
If the fluid is dirty or contaminated, drain the reservoir and replace it.

3. Inspect Steering and Suspension Components

Lift the vehicle using a jack and secure it with jack stands.
Visually inspect the tie rods and ball joints for wear. Look for any cracks or play in the components.
If any parts are worn or damaged, remove and replace them using a socket set.

4. Check and Replace CV Joints

Inspect the CV joints and boots for tears or damage.
If the boots are torn, replace them and add new grease to the CV joint. If the joint itself is damaged, it must be replaced.
To replace, remove the axle nut, disconnect the lower control arm, and pull out the CV axle from the transmission.

5. Wheel Bearing Inspection

Spin the wheel while listening for grinding noises that indicate worn bearings.
If necessary, replace the wheel bearing by removing the wheel, brake caliper, and hub assembly.

6. Reassemble and Tighten Components

Reinstall any removed components, ensuring all fasteners are tightened to the manufacturer's torque specifications.
Reconnect the battery once all repairs are complete.
