Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Suspension Components

Remove the Front Wheels
- Use a lug wrench to loosen and remove the lug nuts.
- Lift the vehicle with a jack and secure it with jack stands.
Examine Control Arm Bushings
- Inspect the control arm bushings for cracks or excessive wear.
- If damaged, remove the control arm bolts and replace the bushings.
- Torque the control arm bolts to the manufacturer’s specifications (typically around 40-50 Nm).
Check Tie Rods
- Inspect the inner and outer tie rods for play or damage.
- If necessary, remove the tie rod end from the steering knuckle using a tie rod separator.
- Replace with new tie rods and torque to specifications (typically around 30 Nm).
Inspect CV Joints
- Check the CV joint boots for tears or leaks.
- If the CV joint is damaged, remove the axle nut and detach the axle from the hub.
- Replace the CV joint or axle assembly and torque the axle nut to manufacturer specifications (typically around 200 Nm).

3. Reassemble and Test

Reinstall Front Wheels
- Place the wheels back on the vehicle and hand-tighten the lug nuts.
- Lower the vehicle from the jack stands and torque the lug nuts to specifications (typically around 120 Nm).
Reconnect Battery
- Reconnect the battery cable if it was disconnected earlier.
