Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety while working on the electrical system.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick.
If low, add the manufacturer-recommended power steering fluid until it reaches the appropriate level.
Check for any debris or contamination in the fluid.

3. Inspect Power Steering Pump

Locate the power steering pump.
Visually inspect for any signs of leaks or cracks.
Test the pump's electrical connection with a multimeter to ensure proper voltage supply.
If the pump is faulty, remove it by disconnecting the hoses and mounting bolts.

4. Examine Steering Rack and Pinion

Locate the steering rack and visually check for any signs of damage or leaks.
Ensure that the tie rod ends and bushings are in good condition.
If the rack is damaged, remove it by loosening the mounting bolts and disconnecting it from the steering column.

Refill the power steering fluid if it was drained.
Reconnect the battery and start the engine.
Turn the steering wheel from lock to lock to bleed any air from the system.
