1. Locate the power steering reservoir.
2. Check the fluid level; top off with manufacturer-recommended fluid if low.
3. If fluid is contaminated or has a burnt smell, drain and replace it.
Tools Required: Fluid pump, funnel, container for old fluid.

3. Replace Worn Steering Components

Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Remove the front wheels for better access to the steering and suspension components.
3. Inspect tie rods and ball joints for wear; replace if necessary.
4. Use a torque wrench to tighten new components to manufacturer specifications.
Tools Required: Socket set, torque wrench, ball joint separator.

4. Inspect and Replace Suspension Components

Sub-steps:
1. Examine struts and shock absorbers for leaks or damage.
2. Replace any worn bushings.
3. Reassemble the suspension, ensuring all bolts are torqued to specification.
Tools Required: Spring compressor (if replacing struts), socket set, torque wrench.

5. Wheel Bearing Inspection

Sub-steps:
1. Spin the wheel by hand; listen for grinding noises indicating a bad bearing.
2. If noise is present, remove the wheel hub and replace the bearing.
3. Reassemble and torque the hub assembly to specifications.
Tools Required: Hub puller, socket set, torque wrench.
