### Step 5: Inspect the CV joint boots
Carefully examine the condition of the CV joint boots. Look for any signs of wear, such as cracks, tears, or holes. Additionally, check for grease leakage, as this is an indication of a damaged boot.
### Step 6: Check the boot clamps
Inspect the clamps that secure the CV joint boots in place. Ensure they are tight and properly positioned. Loose or missing clamps can lead to dirt and moisture entering the boots, causing premature CV joint failure.
### Step 7: Assess CV joint movement
Gently grip the CV joint and attempt to move it in different directions. There should be minimal play or movement. Excessive movement indicates worn-out joints that may need to be replaced.
### Step 8: Clean and lubricate the CV joints
If the CV joints appear to be in good condition, use a shop towel or rag to wipe off any dirt or debris. Apply a small amount of CV joint grease to the joints, ensuring they are adequately lubricated.
### Step 9: Reinstall the CV joint boots and wheels
If the CV joint boots were removed for inspection, carefully reattach them using new clamps if necessary. Reinstall the wheels and tighten the lug nuts securely.
### Step 10: Lower the vehicle and test drive
Safely lower your vehicle from the jack stands and remove the stands. Take your car for a short test drive to ensure that the CV joints are functioning correctly. Listen for any abnormal noises or vibrations.
