Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure it is securely lifted with jack stands.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace Suspension Components

Control Arms and Bushings
- Remove the wheel to access the suspension components.
- Inspect the control arm bushings for cracks or excessive wear.
- If damaged, remove the control arm by unbolting it from the chassis and ball joint. Use a socket set for this.
- Replace the control arm with a new one, ensuring to torque the bolts to the manufacturer's specifications (typically around 70 Nm for M12 bolts).
- Install new bushings if applicable or as a complete control arm assembly.
Tie Rods
- Check the tie rod ends for any play by pulling and pushing them.
- If worn, remove the tie rod end from the steering knuckle using a ball joint separator.
- Replace with a new tie rod end and tighten to manufacturer specifications.
CV Joints
- Inspect the CV joints for any tears in the boot or excessive play.
- If necessary, remove the axle by unbolting it from the hub and transmission.
- Replace the CV joint or axle assembly as needed, ensuring proper installation and torque specifications.

3. Reassemble and Test

Reattach the wheel and lower the vehicle.
Reconnect the battery.
Test drive the vehicle to ensure the noise is resolved.
