Solution

1. Preparation

Gather necessary tools and park the vehicle on a level surface.
Ensure the engine is off and the keys are removed from the ignition.
Disconnect the battery before starting work on electrical systems.

2. Check and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, add the recommended fluid type (Honda PSF or equivalent).
If fluid is dark or contaminated, proceed to replace it:
- Sub-steps:
  - Using a turkey baster, remove old fluid from the reservoir.
  - Refill with fresh power steering fluid.
  - Turn the steering wheel from lock to lock to bleed air from the system.

3. Inspect and Replace Power Steering Pump

Locate the power steering pump.
Check for any signs of leaks or damage.
If the pump is faulty, remove it:
- Sub-steps:
  - Disconnect the power steering pump belt using a socket set.
  - Remove the mounting bolts and disconnect the fluid lines (use a catch pan for spills).
  - Install the new pump by reversing the removal steps and torque bolts to specifications (typically 15-20 ft-lbs).

4. Inspect and Replace Drive Belt

Locate the drive belt connected to the power steering pump.
Check for signs of wear, cracking, or looseness.
Replace the belt if necessary:
- Sub-steps:
  - Loosen the tensioner and remove the old belt.
  - Route the new belt around the pulleys, ensuring proper alignment.
  - Re-tension the belt according to the manufacturer’s specifications.

5. Check Wheel Bearings and Suspension

Raise the vehicle using a jack and secure it with jack stands.
Inspect wheel bearings for play by grabbing the wheel at 12 and 6 o’clock and checking for movement.
If bearings are worn, replace them:
- Sub-steps:
  - Remove the wheel and brake caliper.
  - Take off the hub assembly and replace the bearings.
  - Reassemble all components ensuring correct torque specifications.
