Any idea why this would happen? It starts buzzing/vibrating at about 3500-4000rpms. I have no idea why. Car has an RPS clutch with about 3k miles on it, hasnt happened before, clutch/flywheel issues? Diff? Appreciate all input.


Mods, I double posted this because Im not sure if its a clutch or a rear end issue.

What mile an hour ??

Its rpm dependant, not speed related. Thats why Im thinking something to do with the clutch assembly, or something being vibrated by the motor?

Its rpm dependant with the clutch in or in neutral ?? Stationary or moving ??

I havent tried it stationary yet, but it happens at that rpm in first, second and third so far that Ive checked. EVery time.

Is it kinda cyclic or steady ??

Could be the driveshaft. Might want to turn it 180* just to see if it changes anything. Next, I would take a look at the standard stuff.... engine mounts, transmission mount, torque arm mount etc...

If it doesnt stick out like a sore thumb, it very well might be your clutch. Your RPS clutch doesnt have any centrifugal assist on the pressure plate does it ??

I dont believe so. But its strange that it would suddenly start doing this. i;d be very surprised if it turns out to be the clutch, its been flawless till now.
