Hello everybody. My car is a 1983 Euro 928s.
So, I've refurbished the whole dual clutch and installed it tonight. When I start the car and idle, the clutch makes a "squek'y" sound. As soon as I press the clutchpedal down it disappears and everything is silent. It is like a fast "squek, squek, squek, squek" that follows the rpm of the car. What have I done wrong? Misalignment? Should I remove the clamp, pressureplate etc and have everything re-mounted again? New discs, throw-out bearing, plastic releasearmbushing, guidetube and crank-bearing was installed. Other parts was very carefully checked and was in pristine order. I followed all the great info from here on rennlist, and followed the servicemanual as best as possible. So, fire away, where du you think I should start..

Which parts of the assembly did you lubricate, and with which lubricant?

I followed all your advice and other inputs from rennlist, and ofcourse the servicemanual.
These parts were lubed;
Discsplines.
Guidetube/inside of throw out bearing.
Thrustwasher, against feather springfingers.
Intermidiate axel splines and tip against guidebearing.
Snap-lockring against thrustwasher.
Release arm touchpoints against T-O bearing.
Plastic cupbushing on top of the releasearm.
These parts were carefully and very moderately lubed with no excess.

I'm going under the car tonight or tomorrow. Remove the clamp etc. and see that everything is aligned, rotates freely and looks ok. Somewhere I did something wrong. Just cannot figure it out since I followed the procedures so closely...

State of the torque tube bearings?

RPM-dependent squeak-squeak only when the clutch is engaged (foot off the pedal) suggests the spinning driveshaft (or intermediate shaft) is making a noise. So anything along that axis- pilot bearing, guide tube, or some new squeak in the torque tube due to some imbalance of the new clutch assembly. Was the clutch pack balanced to the flywheel?

does the new guide tube fit the TOB or is it loose?

look to see if the front driveshaft support bearing has migrated forward it should be about 14 inches back
