Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Safety: Disconnect the battery before beginning work on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Check the fluid level; if low, top off with the manufacturer's recommended fluid.
If the fluid appears dirty or contaminated, drain and replace it.

3. Check and Replace Worn Suspension Components

Raise the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels to access the suspension components.
Inspect the tie rods and ball joints for play or wear. If damaged, replace them:
- Sub-steps for replacement:
  - Disconnect the tie rod end or ball joint from the steering knuckle.
  - Remove the retaining nut and bolt.
  - Install the new component and torque it to the manufacturer’s specifications.

4. Inspect and Replace Wheel Bearings (if necessary)

Remove the brake caliper and rotor to access the wheel hub.
Check for any play in the wheel bearing by grabbing the wheel at the 12 and 6 o'clock positions and rocking it.
If worn, replace the wheel bearing:
- Sub-steps for replacement:
  - Remove the wheel hub assembly.
  - Press out the old bearing and install the new one using a bearing press.
  - Reassemble the hub and torque to specifications.

5. Examine and Replace CV Joints (if necessary)

Inspect the CV joints for any torn boots or grease leakage.
If damaged, replace the CV axle:
- Sub-steps for replacement:
  - Remove the axle nut and disconnect the CV joint from the transmission.
  - Pull the axle out of the hub.
  - Install the new axle and secure with the axle nut, torquing to specifications.
