Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues during repair.

2. Inspect Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; top off with manufacturer-recommended fluid if low.
Inspect the fluid for any discoloration or contamination.

3. Check for Leaks

Visually inspect all power steering hoses and connections for signs of fluid leaks.
If leaks are found, replace the damaged hoses or fittings.
Clean any residual fluid to identify new leaks after the system is reassembled.

4. Examine Steering Linkage

Raise the front of the vehicle and secure it with jack stands.
Inspect the tie rod ends and steering rack for play or excessive wear.
Replace any worn or damaged components as necessary.

5. Test Power Steering Pump

With the engine running, listen for unusual noises from the power steering pump.
Use a pressure gauge to check the pump's output; replace the pump if it does not meet specifications.

6. Inspect Steering Rack

Check the steering rack for any signs of fluid leakage or physical damage.
If the rack is faulty, remove it by disconnecting the tie rods and securing bolts.
Install a new steering rack according to manufacturer specifications.
