Solution

1. Preparation

Gather tools and materials: jack, jack stands, socket set, torque wrench, screwdriver set, and safety glasses.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues while working.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Components

A. CV Joint Inspection

Remove the wheel using a socket set.
Inspect the CV joint for any torn boots or excessive play.
If damaged, replace the CV joint by:
1. Removing the axle nut using a socket.
2. Detaching the lower control arm from the knuckle.
3. Pulling the axle out of the hub and replacing it with a new one.

B. Sway Bar Links and Bushings

Locate the sway bar links and bushings.
Inspect for cracks or wear; replace if necessary by:
1. Removing the nuts from the sway bar link using a wrench.
2. Installing new sway bar links and tightening to manufacturer specifications.

C. Suspension Components

Inspect struts and shocks for leaks or damage.
If replacement is needed:
1. Remove the bolts securing the strut to the knuckle.
2. Detach the strut from the vehicle.
3. Install the new strut and torque the bolts to the manufacturer’s specifications.

4. Reassemble and Lower the Vehicle

Reinstall the wheel and torque the lug nuts to the specified value.
Lower the vehicle and reconnect the battery.
