Central Bearing - Propeller Shaft
After hearing noise under the car I looked and I found one bolt - that supposed to attach central bearing from the propeller shaft to the body - missing and the other one loose. The car is almost 3 years old, 70.000 km and serviced at Subaru every 15.000 km. How could this happen? Is there anything I could have done wrong? Could something from under the car (like a rock) do this (unscrewing the bolt) without damaging anything to the exhaust system? And if this was like this for a number of km, is there damage already done to the propeller shaft? I attached the central bearing to the body now and everything seems fine. Subaru service is in vacation now until January.
Thank you for taking the time to read and help!
