I have a 2004 and have had to replace transmission, and replace brakes a lot
You need to replace the engine mount on the right side (if you're sitting in the car), and the transmission mount, underneath the air cleaner. They go bad on all of these before the 2004 model year. You have to replace both, because the engine mount will go bad after just a week or two, if you don't replace the transmission mount also. They cushion the rest of the wagon from the vibration of the engine, so when they're bad, the vibration of the engine causes the whole vehicle to shake, making a loud roar like a truck or tractor. Often, these would go bad after the wagon only had 1500 or 2000 miles on it.
