Solution

1. Preparation

Tools Needed: Socket set, torque wrench, OBD-II scanner, multimeter, steering wheel puller.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Replace Power Steering Fluid (if applicable)

Locate the power steering reservoir.
Remove the cap and check fluid level; add manufacturer-recommended fluid if low.
If the fluid appears dark or contaminated, perform a fluid flush:
- Disconnect the return line from the steering rack.
- Use a siphon pump to drain old fluid into a suitable container.
- Reconnect the return line and fill the reservoir with new fluid.
- Start the vehicle and turn the steering wheel from lock to lock to circulate the fluid, checking for leaks.

3. Examine and Service Steering Column

Remove the steering wheel:
- Use a steering wheel puller to carefully detach the wheel.
- Disconnect any wiring harnesses connected to the steering wheel.
Inspect the steering column for any signs of binding or obstruction.
Lubricate the column with manufacturer-approved grease if necessary.

4. Check Electric Power Steering System

Reconnect the battery and turn on the ignition.
Use an OBD-II scanner to check for any fault codes related to the electric power steering system.
If codes are present, follow the manufacturer’s guidelines for troubleshooting and repair.

5. Inspect and Replace Tie Rod Ends and Ball Joints

Lift the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels for better access.
Inspect tie rod ends and ball joints for signs of wear or damage.
Replace any worn components with OEM parts, following torque specifications for installation.
