Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Worn Components

Steering Components
- Remove the front wheels using a socket set.
- Inspect the tie rods and ball joints for any play or damage.
- If worn, replace the tie rod ends and/or ball joints.
  - Tools Required: Socket set, torque wrench
  - Torque to manufacturer specifications (typically around 50-70 Nm for tie rods).
Suspension Components
- Check the control arm bushings and struts for signs of wear.
- If the bushings are cracked or degraded, remove the control arm and replace the bushings.
  - Tools Required: Socket set, bushing removal tool
  - Torque the control arm bolts to manufacturer specifications (usually around 100 Nm).
CV Joints
- Inspect CV joints for torn boots or grease leakage.
- If damaged, replace the entire CV axle assembly.
  - Tools Required: Socket set, pry bar
  - Ensure proper grease is used and torque the axle nut to specifications (typically around 200 Nm).

3. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Reconnect the battery and perform a test drive to confirm the noise has been resolved.
