Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during the repair.

2. Check and Replace Power Steering Fluid

Locate the power steering reservoir and remove the cap.
Inspect the fluid; it should be clear and at the proper level. If it's discolored or low:
- Use a turkey baster to remove old fluid.
- Refill with the manufacturer-recommended power steering fluid (Toyota ATF Type T-IV).
Start the engine and turn the steering wheel from lock to lock to circulate fluid. Check for leaks again.

3. Inspect and Repair Steering Components

Lift the vehicle using a jack and secure it with jack stands.
Visually inspect the power steering pump, hoses, and connections for wear or leaks.
If leaks are found, replace the affected hoses or components. Tighten any loose fittings.
Inspect the steering rack; if it's leaking or damaged, it may require replacement.

4. Address Steering Linkage and Suspension

Check the tie rods and ball joints for wear. If they feel loose:
- Remove the wheel and inspect components closely.
- Replace any worn tie rods or ball joints.
Check for proper alignment; if misaligned, perform a wheel alignment.

5. Reassemble and Test

Reattach any components that were removed for inspection.
Reconnect the battery.
Start the vehicle and perform a test drive to ensure the issue is resolved.
