Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and a steering wheel puller.
Ensure the vehicle is parked on a level surface and the engine is off. Engage the parking brake.

2. Inspect and Tighten Steering Components

Sub-steps:
1. Remove the steering wheel cover if necessary to access the steering column.
2. Tighten any loose bolts or nuts on the steering column and associated components.
3. Use a torque wrench to ensure all fasteners are tightened to factory specifications.

3. Replace Worn Suspension Components

Sub-steps:
1. If any suspension components (such as tie rods or control arms) are found to be damaged, remove the old part by loosening the bolts and using a pry bar if necessary.
2. Install the new component and tighten it to the manufacturer’s torque specifications.
3. Reassemble any removed components and ensure proper alignment before lowering the vehicle.

4. Check and Replace Wheel Bearings

Sub-steps:
1. Lift the vehicle and remove the wheel to access the hub assembly.
2. Inspect the wheel bearing for any signs of excessive play; if necessary, remove the bearing.
3. Replace with a new wheel bearing and ensure it is properly seated.
4. Reinstall the wheel and lower the vehicle.

5. Final Assembly and Testing

Sub-steps:
1. Reassemble any components that were removed during inspection.
2. Perform a test drive to ensure the knocking noise has resolved.
3. Recheck all newly installed components for proper tightness after the test drive.
