sorry for the delay. this plate of metal is the culprit. it isnt included in mount kits so i feel like it has another name.

not quite. it sits beneath the mount, and acts as a direct buffer plate for the spring.

toyota if you dont want to do anything

mercedes if you hate yourself

really hard to say without looking at it. is it vibrating only when you move or stationary also?

you should barter. a lot of people will take it for free. tell them they can have it for free or you have someone else thatll take it.
