Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical systems.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; top off if low with manufacturer-recommended fluid.
If fluid is dark or contaminated, drain and replace with fresh fluid.

3. Replace Worn or Damaged Steering Components

Tools Required: Socket set, torque wrench, jack and jack stands.
Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the wheel to access the steering components.
Check the tie rods for play. If worn, remove the tie rod end nut and disconnect it from the steering knuckle. Replace with a new tie rod and torque to manufacturer specifications.
Inspect the rack and pinion for leaks or damage and replace if necessary.

4. Inspect and Replace Suspension Components

Inspect struts and control arms for wear; replace if bushings are cracked or components show signs of damage.
Tighten any loose fasteners to the recommended torque settings.
If struts are worn, remove the strut assembly, replace the strut cartridge or complete assembly, and torque all bolts according to specifications.

5. Check and Replace Wheel Bearings

Rotate the wheel by hand; listen for grinding or roughness.
If noise is present, remove the wheel and brake caliper to access the hub.
Use a hub puller to remove the hub assembly if necessary and replace the wheel bearing. Reassemble and torque all components to specifications.
