Hi all. So, I've been having an issue for quite a while now. A year ago or so, I was coming down the highway, when suddenly my car took a little bump and I felt a very strong vibration on the entire car, specially the steering wheel. When I was about to park my car home, I heard a metallic sound like if something had broken, right afterwards the car began vibrating quite a lot. Oh snap I need a new engine mount I thought. So I took it to my personal mechanic and indeed the engine mount was kaput, I bought a new one, changed it and voila, vibration gone. Now, for over a couple of months now, when the car is cold, I can feel the vibrations again, specially when the car is gonna take a bump or a speed bump, and the higher the RPM, the stronger the vibration. This starts to reduce once the engine begins to warm up (I'm thinking that maybe the rubber on the mount gets warmed up and the vibration reduces?) It's getting worse now, everyday I can feel the vibration stronger and it takes longer to reduce... So, given that my engine mount is fairly new, could this be that the transmission mount (opposite side from the engine mount) is starting to break? Or maybe the lower mount I think is called the dogbone? What could be a good way to diagnose which mount is bad? Any help would be appreciated, thanks and excuse my English.
