Car vibrates a lot. And looking at the front mount, it is bad. Since I have to replace it, I was going to replace the passenger side (trans mount?). I see how to replace the front mount. And I think same way with passenger side motor mount except a little more difficult to get to the bolts.

The Driver's side, the large column support 'looks' ok. All the aftermarket ones do not have the internal dampener inside, so I was going to leave that alone since it appears ok. Dealer costs for the mount is EXPENSIVE. If after I'm done with the 2 mounts, I can go replace the drivers side large mount if it really needs it..
I believe there are 4 mounts in this model. But where is the other one?
Do I have to pull the engine to get to wherever that 4th mount is or can I do as I would in the front. But can't find a good diagram where the other 4th one is and how to get to it?

Basically, like I did my Jeep, I would get a flat wood board, approx 8 inch by 24 inch long. Something like that. And support underneath . Slight lift so as not to damage oil pan or Anything else underneath. I would replace the front first since looks the easiest and it is obviously broken. Then with a new mount in front, could proceed to the passenger side- I think this one is the trans mount. Does this sound reasonable?
Any help out there please?
Thanks
