Fault Codes:

P0811 (Excessive Clutch Slippage – can be triggered by drivetrain imbalance) C1044 (Wheel Speed Sensor Fault – may appear if debris contaminates sensor near axle) No dedicated OBD-II code exists specifically for a torn CV joint boot; instead, secondary driveline and ABS codes may be logged when grease loss or joint wear progresses.

The CV joint boot, made of rubber or thermoplastic, protects the constant velocity joint by sealing in grease and shielding it from dirt and water. Over time, exposure to heat, road debris, and flexing causes cracks or splits. Once compromised, grease leaks out, contaminants enter, and the CV joint wears prematurely, leading to noise, vibration, and eventual driveline failure.

Symptoms:

• Grease splatter around the inner wheel or suspension components.
• Clicking or popping noise when turning, especially under acceleration.
• Vibration in the steering wheel or floorboard during driving.
• Clunking sounds when shifting from drive to reverse.
• Progressive drivability issues if the CV joint itself becomes damaged.
