Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface, and the engine is turned off.
• Disconnect the battery for safety.

2. Inspect and Replace Serpentine Belt

• Tools Required: Socket set, belt tensioner tool
• Remove the belt tensioner using the socket set.
• Slide the serpentine belt off the pulleys and inspect for cracks, fraying, or glazing.
• If damaged, replace it with a new belt according to manufacturer specifications.

3. Check Power Steering Fluid

• Tools Required: Funnel, power steering fluid
• Locate the power steering reservoir and check the fluid level.
• If low, fill to the recommended level with the correct type of power steering fluid.
• Check for leaks around the power steering pump and hoses.

4. Inspect and Replace Power Steering Pump (if necessary)

• Tools Required: Socket set, wrench set
• Disconnect the power steering lines from the pump.
• Remove the mounting bolts and take out the old pump.
• Install the new pump and reconnect the lines, ensuring they are tight and leak-free.

5. Wheel Bearing Inspection (if applicable)
