Fcku,
I got both torque struts & the center mount changed when doing timing belt (I did it via a private mechanic). The issue is I feel some more vibration mostly on the passenger side and greater engine noise/hum when accelerating (non when coasting). There is lesser vibration at idle.

I have been buggin 'Darthrouch' too and he has been great like you said.

Now, I strongly suspect that my mechanic did not mark the position of the old mount before he put the new one. And his not available for two weeks!

So my question is:-
Can I (myself) simply support the motor from under, loosen ONLY the 4 bolts that hold the center mount against the rail and try to tweak the position little bit with the floor jack?

(Is this even possible without taking removing upper & lower torque struts and the center mount through bolt. I don't have a T-55 Torx).

Also in my case, is there any way to confirm that it is indeed the center mount alignment that is causing the vibration. (I find it hard to beleive that alignment of the bolt holes of the center mount would cause so much issues!)

How did you get the broken bolt out? my 2000 neon's rear engine mount bolt has sheared off, I don't want to replace the mount, just the bolt, any suggestions?

No, it's not possible. The center bolt that takes the T55 Torx head braces the mount to the engine, so you'd have to loosen all 5 of them. That nut isn't that hard to find or purchase, if you're going that direction.

If you do this, you're most likely going to offset the specs for the upper torque strut also.

Between the center bolt (of the front end of the torque strut) to the eyelet hole where the clip is on the frame that holds the windshield wiper fluid hose (confusing, right?) -- it needs to be 119 mm between those two places.

Easier explanation: (picture) A is ENGINE. B is FRAME. Space between A and B is the UPPER TORQUE STRUT

So you sheered off a nut to the Engine Mount? There's the T55 bolt and 4 regular bolts. Which one?

Tap and Die, + titanium drill bit to core it all out, is the best way doing it alone.

Otherwise... D; Take it to a shop.

The reason that you mark the Motor Mount is because it's already set to Factory Alignment Location. So you mark it to keep it exactly where it's supposed to be.

The problem I have with this is if you're in a car accident and you bust up the mount, fixing the mount then -- it might not actually be aligned which will just destroy the mounts and struts over and over again...

There is a procedure to follow if that is the case. Not sure why that section is cutout of the manual page I posted, but there is one.
EDIT: It looks like I copied over it when I was pasting the pages together.
