1st off to FF. When you say shakes a lot, What do you mean? Does your motor run good? Has a miss or something? If you can find another 20 Focus & compare that motor at idle. If you can open the hood & pre load the atx or let the clutch out some & see if the motor is rolling around or not. Maybe someone can help you w/ this.

front wheel drive motors twist hard under abuse and rip the dry rubber, fresh mounts last 4 to 6 years normally. Common one breaking is passenger and lower tranny, upper tranny may go out but is not really a issue on how it sits. if the lower bone goes you will hear a bump under the hood when you have acceleration from a stop, and hit reverse. the Passenger mount will vibrate almost all of the time.

Ok, thanks. I do have a automatic to its probably more prone to the stick shifts.

More so if you have your foot on the brake & shift from drive to reverse or vice verse. Then you can see the motor roll around w/ the hood open. I'd upgrade to a vf engineering dogbone.

Hey Felix,
I got the CFM dogbone about a year ago...and I've noticed a few things.

The vibration at around 800-900 rpms is normal for the dogbone, I get that. However, with the A/C on I get a lot of vibration at lower engine speeds too...I never torqued the bolt but did a wrench twist and tightened it up without overloading it...

Any suggestions?

I'd tighten the to bolts to 35lbs. W/ the a/c on your going to have the fans kick on, maybe thats your vibration.
