Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely raised with jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect Steering Rack

Tools Required: Wrench set, torque wrench
Check for any movement in the steering rack by wiggling the steering wheel while observing the rack.
If play is detected, replace the steering rack.

3. Check Power Steering Fluid

Tools Required: Fluid container
Remove the cap from the power steering reservoir.
Inspect the fluid level; if low, top off with manufacturer-recommended power steering fluid.
If the fluid is discolored or has debris, flush the system and replace the fluid.

4. Inspect Tie Rods and Ball Joints

Tools Required: Socket set, ball joint separator
Use a ball joint separator to disconnect the tie rod ends from the knuckle.
Check for excessive play by moving the tie rod back and forth; replace if any play is noted.
Inspect the ball joints for wear; replace if there’s any movement when wiggled.

5. Examine Suspension Components

Tools Required: Pry bar, socket set
Inspect control arms and bushings for cracks or excessive wear.
Use a pry bar to check for play in bushings; replace any worn components.

6. Check Steering Column and Alignment

Tools Required: Alignment tools (if available)
Inspect the steering column for any looseness or wear in connections.
If misalignment is confirmed, perform a wheel alignment to ensure proper steering response.
