I changed mine last night and WHAT A DIFFERENCE!
Passenger side was cakewalk and after not being done for 103,000 on my car, those bolts were STUCK in there. Had to put all my 210lb body into breaking them loose. Drivers side was tricky. Others go down by removing the air flow meter/fuel distributor and going down through the intake manifold. I tried something similar, but it didn't work out and I didn't want to mess around with stuff I don't have to remove. I opted to take a tighter route, I removed the ignition coil put and put it to the side. Then just wiggle your arm in where the motor mounts sit and feel around for that 17mm bolt on top. Drivers side was WAY more difficult to break free than the passenger side. PB blast, let it sit for 5 minutes, add some more PB blast, then wait 10 minutes. Broke free easily.
Engine sits noticeably higher in the engine bay. ALL shaking is gone gone gone! My steering wheel went from jackhammer to "is the car on?" The difference is completely worth my bruised knuckles and stripped skin.
So if y'all are having some vibrations, it's time to do those engine mounts.
Just a friendly reminder.
