Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Inspect and Replace Steering Components

Tools Required: Socket set, torque wrench, jack and jack stands, pry bar, safety gloves.
Inspect the tie rod ends:
- Remove the wheel on the side where the knocking is present.
- Use a pry bar to check for play in the tie rod ends.
- If worn, remove and replace the tie rod ends.
- Torque to manufacturer specifications (typically around 40-50 ft-lbs).
Inspect the ball joints:
- Check for wear using a similar pry bar test.
- If defective, remove the ball joint using a ball joint separator.
- Install the new ball joint and torque to specifications (usually about 32-45 ft-lbs).

3. Check Suspension Bushings

Remove the lower control arm if necessary:
- Unbolt the control arm from the chassis and the steering knuckle.
- Inspect the bushings for cracks or deterioration.
- Replace any damaged bushings and reassemble the control arm, torquing to specification.

4. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery.
Test drive the vehicle to ensure the knocking sound is no longer present.
