I don't get how those thing break. Where is the pressure coming from? cenrcer1, what did you do to make this stop happening? Tell me again, I don't understand your wording. If you know where I could get metal ones, tell me please, this happened to me like three times already. Maybe it's because of a bad wheel alignment, it's putting too much pressure on the part. It also seems a little weak and small for it's function.
