Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent accidental electrical issues.

2. Inspect and Replace CV Joints

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar.
Remove the wheel of the affected side.
Inspect the CV joint boots for tears or leaks; if damaged, proceed to replace the CV joint.
Remove the axle nut using a socket set and pull the axle out of the hub.
Use a pry bar to remove the CV joint from the transmission, if necessary.
Install the new CV joint and reassemble in reverse order, ensuring the axle nut is torqued to manufacturer specifications (usually around 200-250 Nm).

3. Check and Replace Wheel Bearings

Tools Required: Bearing puller, socket set, torque wrench.
After removing the wheel, inspect the wheel bearing by spinning it; listen for unusual noises.
If the bearing is faulty, use a bearing puller to remove it from the hub assembly.
Install the new wheel bearing, ensuring it is pressed in correctly and torqued to specifications (generally around 170-220 Nm).
Reinstall the wheel and lower the vehicle.

4. Inspect Steering and Suspension Components

Tools Required: Wrench set, socket set, torque wrench.
Inspect tie rod ends for damage or play; replace if necessary.
Check the steering rack for leaks or damage; replace if faulty.
Inspect all suspension components for wear, particularly struts and bushings, and replace if needed.
