Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Power Steering Fluid

Check the power steering fluid reservoir for level and clarity.
If the fluid is low or contaminated, drain the old fluid using a turkey baster.
Refill with manufacturer-recommended power steering fluid (Toyota PSF or equivalent) until full.

3. Inspect Steering Components

Lift the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels for better access.
Inspect the steering rack for any signs of leaks or damage.
Check the tie rods for play by grasping them and attempting to move them side to side; replace if loose.

4. Check Suspension Components

Examine the ball joints and control arm bushings for excessive wear; look for cracking or separation.
If worn, use a socket set to remove the affected components and replace them with new, OEM parts.
Tighten all bolts to manufacturer specifications.

5. Reassemble and Test

Reattach the wheels and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
Start the vehicle and perform a steering test to ensure the knocking sound is resolved.
