Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the vehicle’s 12V battery to ensure safety while working on electrical components.

2. Inspect and Replace Steering Components

Inspect Steering Rack:
- Remove any covers or shields obstructing access to the steering rack.
- Check for any visible leaks or damage on the steering rack.
Replace Worn Tie Rods:
- Use a socket set to detach the tie rod ends from the steering knuckle.
- Measure the length of the old tie rod to set the new one to the same length.
- Install the new tie rods and secure them according to the manufacturer's torque specifications.
Lubricate Joints:
- Apply appropriate lubricant to the steering joints and bushings if they are dry.
- Ensure that all moving parts are adequately lubricated to reduce friction and noise.

3. Test Power Steering Motor

Reinstall and Reconnect:
- Reconnect the battery and turn the vehicle on without starting the engine.
- Activate the power steering to ensure the motor functions correctly without abnormal noise.

4. Alignment Check

Perform Wheel Alignment:
- Take the vehicle to a professional alignment shop to ensure proper alignment.
- Adjust as necessary according to manufacturer specifications.
