Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues during the repair.

2. Inspect and Replace Suspension Components

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, impact wrench (if necessary).
Lift the front of the vehicle using a jack and secure it with jack stands.
Visually inspect control arms, ball joints, and tie rod ends for signs of wear or damage.
If any components are worn, proceed to replace them:
1. Remove the wheel to access suspension components.
2. Use a socket set to remove bolts securing the damaged component.
3. Use a pry bar if necessary to detach the component from its mount.
4. Install the new component, ensuring to torque bolts to manufacturer specifications (consult service manual for specific torque values).
5. Reinstall the wheel and lower the vehicle.

3. Inspect and Replace CV Joints (if applicable)

Tools Required: CV joint removal tool, socket set, grease.
If the clicking noise persists, inspect the CV joints:
1. Check for visible damage to the CV boot (cracks or tears).
2. If damaged, remove the axle from the vehicle:
  - Remove the wheel and loosen the axle nut.
  - Disconnect the lower control arm or other mounting points as necessary.
  - Slide the axle out of the transmission and replace the CV joint or entire axle assembly.
3. Apply new grease if only the joint is being replaced and reassemble, ensuring all bolts are torqued correctly.
