Hello. I have a 2009 Toyota Venza and there’s been a heavy vibration in the engine. I checked underneath the hood one day and it was shaking like crazy. The first idea that came to my mind would be the motor mounts. It's about to reach 261k and I’ve never had them changed. The dealer said it was all good still and they see no issues. But when I’m driving you can literally see the hood shaking. I don’t think they are good personally speaking but I would like an expert's opinion on this. I tried to take videos of the transmission mount and the motor mount on the passenger side both are located near the fender liners. ( I uploaded a imgur link so you can see the videos below). I changed the dog bone mount already so I don’t think that would be the problem. There is also another one in the engine bay near the driver-side front but that one for sure I know is good. You can hear the clunk when you shift from drive to reverse or from reverse to drive. I also tried to upload a video of the engine shaking but it's hard to see on camera only in person you can see it well. The camera doesn't pick it up well but I tried to zoom in and show the engine shaking. Any feedback would be greatly appreciated.
