Solution

1. Preparation

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

2. Inspect and Replace CV Joints

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar.
Lift the front of the vehicle and secure it with jack stands.
Remove the wheel on the side making the noise using a socket set.
Inspect the CV joint for any tears in the boot or play in the joint.
If damaged, remove the axle nut using a socket.
Detach the CV joint from the wheel hub and pull the axle out of the transmission.
Replace the CV joint or entire axle assembly as necessary, ensuring proper alignment.
Reinstall the wheel, torque the axle nut to the manufacturer’s specification.

3. Inspect and Replace Suspension Components

Tools Required: Socket set, wrench set, pry bar.
With the vehicle still lifted, visually inspect the control arms, bushings, and sway bar links.
If any bushings are cracked or the sway bar links are loose, replace them.
Remove the old components by unbolting them from the chassis and suspension.
Install new parts, ensuring proper torque specifications are followed.
Reassemble the suspension components and lower the vehicle.

4. Check Wheel Bearings

Tools Required: Socket set, torque wrench.
With the vehicle on the ground, check for any wheel bearing play by shaking the wheel side to side and up and down.
If play is detected, remove the wheel and brake components to access the hub assembly.
Replace the wheel bearings if they are worn or noisy.
