Hello my name is ***** ***** thank you for your question.
This vibration, do you feel it feel it only when moving?
The most common thing that I am going to say that can give you a vibration at idle and moving is a bad engine mount. The right side engine mount which is right in front of the engine on the passenger side are the most common engine mounts to go. When that goes it can cause the vibration you are talking about and also produce it when driving. I would have that right side engine mount checked and replaced as needed. I would also have all the others checked. When one mount goes it can put pressure on the others. If you let it go to long it can damage other engine mounts as well.
Do you have any more questions on this?
There is one you didn't replace, I am taking it that it is the rear engine mount?
That is the hardest one anyway! The subframe normally has to come down to remove it.
How is your exhaust mounting?
I would just get under the car and bang around on it to see if it seems loose.
I have a test you can do. I can keep this question open till you do this as well.
Try to get the car up to that 60 mph or so when you are feeling the vibration, if you are handy, you can do this. If you don't feel comfortable then don't do this. Make sure your in a safe location and no many cars or trucks around you and put the car into neutral and turn the car off and coast. See if you still feel the vibration. That will help isolate the vibration. This will tell me if the vibration is in the engine at that speed. If the vibration goes away, you are going to want to recheck your engine mounts. Possibly a after market mount that is to stiff. If you still feel it, then it would be in the wheels. High road force in a tire or wheel bearing or something.
Once you have felt it go away, or stay.. Since you are in neutral coasting, just turn the key to start the car, and put it back into gear to continue driving.
Do you think you can try that?
Ok.. Let me know what you find.
I don't recall anything about a noise.. But that is good so it would mean the noise is either a tire noise or possibly a wheel bearing.
If the vibration went away with the car off, that tells me it's either a engine mount issue or exhaust mounting issue. If the engine mounts are the wrong composite. It may allow the vibration to go through the vehicle instead of absorb it. This is common for After Market engine mounts. So you would normally have someone use a pry bar on the engine in the engine mount area at idle to isolate the area that is causing the vibration.
If you are going 55 mph, and you have a vibration still with the car turned off, that is either tire issue, or a wheel bearing or something
The steering rack can't cause a vibration unless the tie rod ends are loose or something.
