I have owned this car for 2 years now and it is on its third top tranny mount.


The first one went I think due to a bad pot hole. I was able to pull the broken stud out and replace it with a Grade 8 bolt. About a year later that bolt breaks, don't know when or how I just found it like that when I was cleaning the filter. I wasn't able to replace the bolt on that one since it broke inside the shaft. The third one broke last night, the funny thing was all I was doing was backing into my garage. I put it in reverse slowly started to roll back then I hear a pop noise and it felt like I ran something over with the front tire. I check the driveway and there was nothing there pop the hood and sure enough there it is sitting on its side in the hole.
Now is there any reason as to why I am breaking these so often. I don't beat on the car, its only driven on nice days, I have only put 13,000 miles on it in the 2 years I have had it. Would it be possible that something is not aligned correctly?
TIA
