Ok guys, I finished installing my Exedy Stage 2 clutch and flyweel today and it drove fine. But after about 20 min of driving it started making this weird vibration almost like the driveshaft is off balance or something. Its like my tires are completely off ballance all of a sudden. I doubt it's my tires so what do u think it is?
It seems like IDK like the driveshaft is spinning off balance and its vibrating or spinning off a little and making the car shake a lil and giging off a bit of a low frequency hum. Almost like I have a Subwoofer in my car really loud with lots bass. It only happens after 50mph but before it's fine. And after about 75mph it calms down a lil but its still there. Also, once in a while I hear this loud thud from the rear of the car when I shift gears, and I wont even be shifting hard.. Like its a bang when the gear goes in from the rear diffy or driveshaft or something. IDK

PLEASE HELP!!!

 

Anyone?

 

well you mentioned the driveshaft being out of balance... did you mark it when you took it apart?

 

are you sure you bolted the mounts back right??
and why would the drive shaft be outta balance?? your not supposed to take it off for a clutch install

 

Yeah al the mounts are in place....we took it off to move the transfer case around more easily.
And yeah we marked the drivesahft as well.

 

No one else?

 

does the car only do this when your driving, or will it vibrate sitting still when you rev it up??

 

^yeah if it vibrates sitting still one of your pressure plate bolts might be loose.

 

Only while driving guys. I put in in neutral and it doesnt vibrate when I rev it.

 

I wonder what it could be.....

 

Bump....

 

Does the clutch pedal vibrate when the engine is idleing? If it does, it sounds like it is either the clutch pressure plate or flywheel bolt(s) is/are not torqued properly.

 

No, nothing else is out of the ordinary accept for the vibration I was talking about.

 

Bump

 

are you sure you did "EVERYTHING" step by step??? like the pressure plate or flywheel being torqued in the right order with the right torqued specs? and did you use the blue glue thingy for the flywheel bolts?
