Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; if low, top off with the recommended fluid type (Toyota Genuine ATF Type T-IV).
If the fluid appears dirty or contaminated, drain and replace the fluid using a turkey baster or similar tool.

3. Inspect Steering Components

Lift the front of the vehicle using jack stands for safety.
Remove the front wheels to gain access to the steering components.
Check the tie rods for play and replace if necessary (new tie rods should be torqued to manufacturer specifications).
Inspect the steering rack for leaks; if leaking, replace the steering rack assembly.

4. Examine CV Joints

Inspect the CV joints for any tears in the rubber boots or play in the joint.
If damaged, remove the axle nut using a socket set (torque to manufacturer's specifications upon reinstallation).
Replace the CV joint or axle assembly if necessary.

5. Check Wheel Bearings

Spin the wheel by hand and listen for grinding noises.
If noise is present, remove the hub assembly and replace the wheel bearings. Ensure proper torque specifications are followed during reassembly.
