Default V1 driveshaft

When I'm letting go of the clutch and sometimes when I inicially give it gas it seems like I can feel the linkage of the 2 piece drive shaft. Sounds like a small "click" . Is this normal for a v1?

The stock clutch should've been replaced within the first 10,000 miles.

Is there a good way to diagnosis the dual mass flywheel?

100k miles on my stock clutch/flywheel works great. Could be a bad carrier bearing in driveshaft or could be your diff popping around when the Tq applied to it shifts at lower speeds.... solved by a better diff bushing.

Also this may sound dumb but when my car is colder I don't really feel the shifting clunk but when it warms up I feel it more. Anybody ever experience this?

start off by getting under the car and pushing up on the front of the diff..if it moves then that bushing is bad.. the drive shaft even with a bad carrier bearing really wont cause what ur describing. id go with rev shifts bushing as its all poly with no metal outer sleeve to deal with. also with the car in gear and up in the air..rotate the drive shaft back and forth to where u can gauge the amout of roatation the DS spins vs where it engages the gears in the diff.. the diff cases on the stock diff distort and throw off the back lash.(cause of clunk) if it takes a 1/3 or more of a roatation of the DS id start looking for a new diff. once they loosen up that much they tend to grenade... as me how i know lol
