Solution

1. Preparation

Tools Required: Socket set, wrench set, OBD-II scanner, fluid catch pan, multimeter
Park the vehicle on a level surface and ensure the engine is off.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Check and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level. If low, top off with the recommended fluid type (usually ATF or specific power steering fluid).

Sub-steps:
1. Locate the power steering pump (generally near the engine).
2. Disconnect the power steering hoses from the pump using a wrench.
3. Remove the mounting bolts using a socket set and carefully extract the pump from its bracket.
4. Install the new pump by reversing the removal steps and ensure all connections are tight.
5. Reconnect the hoses and ensure there are no leaks.

4. Inspect and Replace Steering Rack (if necessary)

Sub-steps:
1. If the steering rack is found to be damaged, raise the front of the vehicle and secure with jack stands.
2. Remove the front wheels for better access.
3. Disconnect the steering linkage from the rack.
4. Remove any mounting bolts securing the steering rack to the vehicle.
5. Carefully extract the old steering rack and replace it with a new one, securing it with bolts and reconnecting the linkage.
