Solution

1. Preparation

Gather tools and equipment: jack and jack stands, socket set, wrench set, and a torque wrench.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery before starting to avoid any electrical issues.

2. Inspect and Replace Steering Components

Lift the Vehicle
- Use a jack to raise the front of the vehicle and secure it with jack stands.
Check Steering Linkage
- Inspect the tie rods and ball joints for any signs of wear or looseness.
- If damaged, remove the tie rod end by loosening the nut and separating it from the steering knuckle.
Replace Worn Parts
- If any components are found to be faulty, replace them as necessary:
  - Tie Rod Ends: Remove the old tie rod end and install a new one, tightening the nut to the manufacturer’s specified torque.
  - Ball Joints: If they are worn, remove the old ball joint and install the new one, ensuring correct torque specifications are followed.

3. Check Power Steering System

Inspect Power Steering Fluid
- Check the power steering fluid level and top off if low. If fluid is dirty, consider flushing the system.
Examine Power Steering Pump
- Listen for unusual noises from the pump while turning the wheel. If noisy, it may need to be replaced.

4. Test Drive

After repairs, lower the vehicle and reconnect the battery.
Test drive the vehicle to ensure the knocking noise has been resolved.
