Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir and remove the cap.
Check the fluid level; if low, top off with the recommended fluid (Toyota ATF Type T-IV).
If the fluid is dirty or contaminated, drain the system using a turkey baster or a siphon pump.
Refill the reservoir with fresh fluid and bleed the system by turning the steering wheel from lock to lock.

3. Inspect and Replace Steering Rack

Remove any components obstructing access to the steering rack.
Disconnect the steering column from the rack following manufacturer's specifications.
Remove the mounting bolts securing the rack to the chassis.
Carefully pull the steering rack out and inspect for wear or damage.
Replace with a new steering rack if necessary, ensuring proper alignment and torque specifications.

4. Wheel Bearing and CV Joint Inspection

Lift the vehicle and secure it with jack stands.
Rotate each wheel by hand to check for grinding noise or roughness.
If noise is present, remove the wheel and inspect the wheel bearing.
Replace the wheel bearing if necessary, ensuring to use the correct torque specifications for the hub assembly.
Inspect the CV joints for any signs of cracks or leaks in the boot; replace if damaged.

5. Reassemble and Test

Reattach all components in reverse order of disassembly.
Ensure all nuts and bolts are torqued to specifications.
Reconnect the negative battery terminal.
Start the vehicle and check for any abnormal noises before taking it for a test drive.
