Last year I decided to change all of my mounts save for the transmission mount, because I was burning through engine torque mounts every month. I must have replaced that thing 5 times last year.
So I replaced the front, which was completely broken. It wasn't just the hydraulic part that had separated, but the metal had torn as well. In the meantime, I also replaced the rear mount. The rear mount had two bolts to the subframe and one bolt to the block, but two bolt holes. I figured it would be fine to put only one back.
So I put only one back, and shortly after, I would hear a clunking noise when going from reverse to drive or back, and I never knew what it was, until recently.
Recently I blew another front engine mount, and I discovered the reason was because the rear engine mount had started to become loose, so the engine was actually angled forward a bit, putting lateral stress on the torque mount. I quickly found a bolt that fit the second hole, pushed the engine back, and replaced the front mount. The engine torque mount is starting to tear, but is not torn yet, so that'* still in good shape. When I took the side cover off to replace the parking pawl rod in January, the transmission mount seemed fine. A few days ago, I checked the front mount and that seemed fine.
Now the only possible explanation would be a broken rear engine mount because of the way it had flexed due to the missing bolt.. However, would this cause as much vibration as I'm getting now?
