318ti Intermittent Vibration from Rear Hi all, When driving on the highway (around 65-75mph), my car will occasionally begin to vibrate violently. It gets worse very quickly as I continue to drive. Once I slow down to 10mph and speed up again, the vibration is gone. It has done this about 4 times in the past 6 months, with the last 3 occurring within the last couple weeks. It's as if it catches some frequency and only clears when you slow down to stop the oscillation. The car has a 3.73 LSD out of an e30. The PO said the RTABS were replaced. Any ideas? |
