Another T5 Vibration Issue

[Mr. Snrub]

It's not bad under normal driving.. but if you really rev it out or drive faster than 75mph or so in 5th, she shakes pretty good. It's more of a noisy shake than a visible one. Really annoying.

I recently had a new clutch quadrant and firewall adjuster installed as my old ones were going. The guy at the shop who installed it asked me if my clutch was on the way out because he had it adjusted out all the way and the engagement point is still pretty low to the floor.

The clutch is "supposed" to be brand new... but...? I just figured maybe these items are related as I didn't have any vibration problems until I started having some shifting problems. It seems a bit stickier to get in the first couple gears than it should be sometimes as well.

Does it go away when you push the clutch in while driving?

A little.. but not all the way.

Can you absolutely rule out the driveshaft then? I had a vibration similar to that and swap driveshafts and it went away.

Is it a rhythmic vibration by chance?

 

[Mr. Snrub]

I can't rule out the driveshaft completely...
I don't think the clutch is operating correctly.
There is a rhythmic... ever so slight vibration when cruising at around 65-70

I hope someone has figured this out, as I have the same problem. My driveshaft has been balanced twice. has new wheel bearings all the way around.

Well I am sort of fighting a similar issue. I hope that I can find time to pull the driveline apart this weekend. I have a new clutch and 3550 to put in, but would like to examine the current hardware to see what the cause is.

I have been told it could be a bearing at the back of the input shaft causing this.
