What would be a symptom of a worn CV joint?
A worn CV joint typically presents with a distinctive clicking or popping noise when turning, often accompanied by a torn boot that leaks grease. As wear progresses, drivers may also notice vibrations or a less smooth transfer of power. Recognizing these signs early can help prevent a roadside failure.
Common symptoms
Here are the most common indicators that a CV joint is worn or damaged. Note that symptoms often start subtly and worsen with time.
- A sharp, intermittent clicking or popping noise when turning, especially at low speeds; this is typically linked to the outer CV joint
- Vibration or a noticeable shudder during acceleration or at highway speeds, which can grow louder as the joint wears
- Grease leakage or a visibly torn CV boot; you may see grease on the inside of the wheel, under the vehicle, or along the axle
- A clunk or grinding sensation when starting from a stop or during abrupt changes in direction, indicating significant wear
If you notice one or more of these signs, have a qualified mechanic inspect the CV joints and boot promptly to prevent a potential failure that could strand you.
What to do if you suspect a worn CV joint
Taking the right steps can save time and money and reduce risk on the road. Use this checklist to guide action.
- Inspect the CV boots for tears or cracks and check for grease splatter around the wheel, axle, and undercarriage
- Schedule a professional inspection and road test with a mechanic or dealership to confirm joint wear and boot condition
- Avoid long highway trips and high-speed driving until the joint is inspected or repaired, as continued use can cause failure
- Repair options include replacing the boot to prevent further contamination, and replacing the CV joint or axle if wear is evident or the joint has failed
Prompt attention is essential; continued driving on a worn CV joint risks a sudden loss of drive, damage to the axle, or even a dangerous breakdown.
Summary
A worn CV joint usually begins with a turning-related clicking noise and can progress to noticeable vibration, especially during acceleration, along with grease leakage from a torn boot. If any of these signs appear, seek a professional inspection quickly to avoid more extensive and costly repairs.
