I just had a repair shop install an Exedy stage 1 clutch set, struts, and alignment. Picked it up this afternoon and immediately when I started it up noticed a vibration that wasn't there before. The car revved smooth as silk before the install. at 2k rpm it feels like im driving on a rumble strip. It doesn't matter if its in gear, out, moving or stationary it still does it. Spoke to the mech about it and he thinks its because of the new trans mount I had them put in, transmitting vibrations because of it being so stiff. I'm not so sure, I believe its because something is out of balance near the flywheel and now I'm scared to death its going to shake my motor to friggin pieces. Anyone have any ideas? or did I just fork out 700 bucks to have my car destroyed??????

I have the Exedy stage 2 it shook a little bit after install and when the rpms came down. I'm just now at 550 miles since my install and it's going away. Did you have the flywheel resurfaced? I think it's just part of the break in period. I set my trip calculator on my odometer to 0 to see when I reached the 500 mile break in period. When a new clutch is installed it takes 500 city miles for a proper break in and not shifting over 3k rpms. Normal symptoms of a clutch breaking in is chattering when engaging.

You can but shaking at just idle that is a violent shaking isnt normal. If its slight it could just be because its new. Does it shake more the higher the rpms or does it drift away?

I was searching the web and most common issue on vibrations after clutch install was transmission crossmember was mounted backwards which can mount the tranny crooked. 2nd was driveshaft wasn't marked before removal so it was mounted back up not in the original way it was taken off, ultimately not balanced. Then next was flywheel was resurfaced and wasn't resurfaced properly, meaning it was warped after resurfacing.

its gotta be something rotational im sure. the vibration goes in hand with the rpms. its not violent or anything but very very noticable at the same time

It is not uncommon for shops to remove the pressure plate assembly locating dowels when they resurface the flywheel--make sure they got put back in, as it is also not uncommon for repair shops to believe the PP mounting bolts will ensure it is centered--they will not, the dowel pins have to be used. Unfortunately the only way to really tell if the dowels are in there is to pull the tranny.

It would not hurt to ask your mechanic about them, if they get a fuzzy look or hesitate in answering make 'em pull the transmission to be sure. Some mechanics will be pissed off when you ask questions like this, which is good because it means they know what they are doing and are annoyed that you would ask such a stupid question...

it doesn't chatter or shake on engagement, but vibrates according to the rpms. moving, not moving, in gear or out makes no difference. The vibration feels similar to say, a phone on vibrate so to speak. I took it back to the shop and they are going to remove the inspection plate and have a look. Then if they find something they will pull the tranny again. I was told that if it was something they did then no labor charge but if I bought defective parts that I was going to have to pitch in labor charges AGAIN. :wtf So heres to crossing my fingers that they screwed up!!

If you bought the clutch from AM I would be giving them a call right now. If its a defective part I would give them an ear full.

yeah it came from AM. i just got it back again and they found nothing wrong. they do notice the vibration but think the pp or clutch plate is out of balance. i sent AM an email already. when you said your stang shook a little was it just on shifts(chatter)? or was it like what im dealing with now?

If you didn't resurface your flywheel or get a new one that's your problem

I've got the Exedy stage 2 as well. However, no vibrations from mine, I just get an ever slight chatter during the 1-2 shift.

Did you do the install our did a shop do it?

This is why I NEVER have shops touch my car if I can help it. (I AM going to have Wicked do some welding in a few weeks but that is because I can't TIG for isht).

They could have:

-Removed and not re-installed the dowel pins as was already states
-Not done the flywheel as also already stated
-Left hardware loose or not used a torque wrench
-Re-used or forgot to re-install the pilot bearing

At any rate, your first, FIRST order of business when something like this happens is to pull a 180 and go directly back to the shop and make them fix it, no two ways around it. You paid for what is supposed to be a quality install and until you get it you need to be the biggest ******* possible within reason. Sometimes its just an honest mistake or "you know who" had his/her hands on the car and they'll just fix it for you and you'll be on your way.

Very worst case scenario you may have to go to another shop because taking legal action will be more expensive than getting a good shop to redo it. The best thing you can do in this case is spread word of mouth on a bad shop and hope it does enough damage where they lose business.

Also if this shop is called anything like "XTREME" or "XCLUSIVE" or "X-OTIC" or anything like that I don't feel bad for you.
