I bought a wheel hub assembly a month ago. Yesterday one of the wheel studs snapped which should not happen because I always use a torque wrench. When I asked for the warranty, they told me that studs are not covered under warranty? Really? On top, if they ever accept your claim, they will not refund you money. They will replace it with another defective, bad quality part and you will have the same problem again and again. So buy a quality part somewhere else. Your safety is more important.
