Remove the Wheel
- Use a lug wrench to loosen and remove the wheel bolts.
- Take off the wheel to access the suspension components.
Check Suspension Bushings
- Inspect control arm bushings for cracks or wear.
- If damaged, proceed to replace them.
Replace Control Arm Bushings
- Use a bushing removal tool to extract the old bushings.
- Press in new bushings using a hydraulic press or a suitable tool.
- Reinstall the control arms, torque bolts to manufacturer specifications (usually around 45-65 Nm).

3. Inspect and Replace CV Joints

Inspect CV Boots
- Look for tears or leaks in the CV boots.
- If damaged, replace the CV joint assembly.
Remove the CV Axle
- Remove the axle nut using a socket (typically 30-36 mm).
- Disconnect the CV axle from the wheel hub and transmission.
Install New CV Axle
- Insert the new CV axle into the wheel hub and transmission.
- Torque the axle nut to the specified value (usually around 200 Nm).
- Reattach the wheel.
