Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, chassis ear or mechanic's stethoscope.

2. Lift the Vehicle

Use the jack to lift the front of the vehicle.
Securely place jack stands under the vehicle to ensure safety.

3. Remove Wheels

Remove the front wheels to gain access to the suspension components.
Tools Required: Lug wrench.

4. Inspect and Replace Components

Ball Joints:
- Use a pry bar to check for play in the ball joints. If excessive play is detected, replace them.
- Sub-steps:
  1. Remove the cotter pin and nut from the ball joint.
  2. Use a ball joint separator to detach it from the control arm.
  3. Install the new ball joint and torque to the manufacturer’s specifications (typically around 40 Nm).
Tie Rod Ends:
- Check for looseness and replace if necessary.
- Sub-steps:
  1. Remove the nut securing the tie rod end to the steering knuckle.
  2. Use a tie rod end puller to disconnect it.
  3. Install the new tie rod end and torque to specifications (approximately 50 Nm).
Strut Mounts:
- Inspect strut mounts for wear; replace if they show signs of damage or separation.
- Sub-steps:
  1. Remove the top strut mount bolts.
  2. Detach the strut from the knuckle and remove it.
  3. Replace the strut mount and reassemble, torquing to specifications.

5. Reassemble

Reattach the wheels and lower the vehicle back to the ground.
Tools Required: Torque wrench for wheel lugs.

6. Final Checks

Ensure all fasteners are secure and components are properly installed.
Prepare for a test drive to verify the repair.
