Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is on a flat surface and securely parked.
Disconnect the battery to avoid any electrical issues while working.

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, add the appropriate power steering fluid (consult owner's manual for specifications).
Inspect the fluid for contamination or debris; if dirty, proceed to flush the system.

3. Address Leaks

Examine hoses and connections for any signs of leaks.
If leaks are found, replace damaged hoses or seals.
Use a torque wrench to tighten any loose connections to manufacturer specifications.

4. Check Power Steering Pump

Remove the drive belt from the power steering pump.
Inspect the pump for any signs of damage or wear; test its operation by rotating the pulley by hand.
Replace the pump if it feels stiff or produces noise while turning.

5. Inspect Steering Rack and Pinion

Raise the vehicle and secure it on jack stands.
Remove the wheels for better access to the steering components.
Inspect the steering rack for any signs of damage, wear, or binding; replace if necessary.

6. Reassemble and Test

Reinstall components in reverse order.
Ensure all connections are secure and the fluid level is correct.
Reconnect the battery and perform a test drive to confirm that steering has returned to normal.
