My 2005 Jetta developed the telltale vibration of a failing DMF so I replaced both it and the clutch with the Valeo kit from BoraParts (awesome service and kit BTW). I followed the instructions in the Bentley manual and the .pdf linked on the first page of this thread. I found the whole process pretty easy and only ran into a couple of snags.
1) Getting the dang shift weight off was a pain until I decided to loosen the nut, place a small (1/2") wooden block under the weight and tap on the nut with a hammer and 1/2" extension bar like this:
2) I decided not to remove the drive flanges from the differential as I didn't want to end up with tranny fluid all over the garage floor. This made getting the transmission out difficult as the driver's side flange kept hanging up on the I-frame and driveshaft. The solution was to disconnect the sway bar bolts on both sides and rotate the bar out of the way. This allowed me to tie the driveshaft up higher so that the flange would clear. This is the bolt I removed:
Contrary to the instructions, I didn't have any problems with the power steering line, I tied it up in a couple of places and it stayed out of the way. It was in the way when I was loosening the fill plug to change the fluid, but that was minor.
I ended up using an engine hoist to remove and install the trans rather that a transmission jack. I've always done it this way and it works great since you can be under the car when re-installing the tranny and you can rotate it freely to get the splines lined up. Getting the trans back in took about 5 minutes this way.
When I got the tranny out, I took at look at the flywheel and was surprised to see that the inner hub that the clutch mates with was off center from the outer portion by about 1/8". I actually had to lever it more to center to get the flywheel bolts out. I can move the inner portion back and forth by hand a little bit which cannot be good. In addition, the actual inner ring that bolts to the crank is loose and rattles inside the flywheel. I'm sure that was the source of the noise and the off center hub caused the nasty vibration. I'm glad I decided to change it when I did.
I've got about 500 miles on the new clutch and it's fantastic! Takeup is super smooth and there's not a hint of chatter to be found.
Thanks to BoraParts for the flywheel kit and rear engine seal, 1stVW Parts for the trans fluid and throwout bearing sleeve, TDI Parts for the Metalnerd triple square socket kit and Harbor Freight for the engine support bar.
