Ten Four

Basically my S2000 drives great and my cousin's has this horrible vibration on decel and on accel in lower RPM. I have NFI what the problem is. Pretty sure it isn't clutch buzz as mine makes the typical clutch buzz sound. Have replaced diff rear mounts (fronts look fine), driveshaft.. Might try engine mounts next (they look fine though)... Could it be the actual diff?
It feels like its coming from the middle / rear of the car. The noise goes away after a certain rpm on the way down and way up (low rpm).

Car isn't lowered.

Isn't engine mounts...

Isn't diff.

I'm out of ideas.


Clutch???

Possibly pitted CV buckets. Seems like the car is jerking when you let off the gas, but relatively smooth while accelerating.

vibration during acceleration means CV buckets. i would take a gander at that. Engine mounts you can tell if there is liquid coming out of them its time to change it.

Isn't jerky at all, just the vibration. We swapped the whole driveshaft / CVs etc with a known good car so isn't that.

I honestly think its clutch now, its slipping just a little bit at high rpm.

Swap the CV buckets, cheap and you will be able to see if they are pitted once you get them off.
