I have been having vibration issues with my car while driving on the highway. Most of the vibration is felt through the gas pedal (like a foot massager). Shifting gears could also be a lot smoother. I have replaced just about every suspension part and my rear diff mount is not leaking. I have been annoying with posts on here because I do not know what is causing this feeling. Feels like my car is going to break apart over bumps and every small crack is felt through the gas pedal.

Another example...if I'm going 70 on the highway, back off the gas for a second, then just tap the gas pedal slightly the whole car jerks like the drivetrain is trying to catch up to the wheel speed. The whole car feels like it lurches forward and backs off. Kind of hard to explain.

Here are videos to show how much the engine moves. I'm pretty sure it's banging too as the whole car rocks when I rev it in neutral.



Thanks,
Aaron

 

I put a jack under the engine and raised it a little bit with all mounts still connected. Normal?

I need help guys!
