Solution

1. Preparation

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

2. Inspect and Replace Power Steering Fluid

Using a funnel, check the power steering fluid reservoir. If low, top off with the recommended fluid type (Toyota ATF Type T-IV).
If the fluid is dirty, proceed to replace it:
- Locate the power steering pump and remove the return line using a wrench.
- Drain the old fluid into a suitable container.
- Reconnect the return line and refill the reservoir with fresh fluid.

3. Check and Repair Steering Linkage

Raise the front of the vehicle using a jack and secure it with jack stands.
Inspect the tie rods and ball joints for any signs of wear or damage.
If any components are damaged, replace them:
- Use a socket set to remove the damaged tie rod or ball joint.
- Install the new component and secure it to the correct torque specifications as stated in the manufacturer’s service manual.

4. Inspect Suspension Components

Examine the control arms and struts for damage or misalignment:
- If any part is damaged, replace it with a new part.
- Re-align the suspension components as necessary, ensuring they are torqued to the specified values.

5. Test Steering Functionality

Lower the vehicle and reconnect the battery.
Start the engine and turn the steering wheel side to side to ensure fluid circulation.
Check for any unusual noises or resistance.
