I need a new driveshaft for my G4 ASZ

Hello everyone,
ich habe mal wieder ein Problem mit meinem G4 mit ASZ Motor. Nach nun mehr 330tkm musste das vordere rechte Radlager gemacht werden und die Antriebswelle hat auch schon beim ein- und ausparken geknackt. Da ich die Welle auf der Fahrerseite auch schon tauschen musste und ich das Aussengelenk trotz diverser Hilfsmittel nicht abbekommen habe, wollte ich mir die Quälerei auf der Beifahrerseite sparen und habe gleich eine komplette SKF Welle geordert. Eingebaut war sie schnell und nach der ersten Probefahrt kam die Ernüchterung. Die Karre dröhnt und vibriert wie verrückt. So ein Mist, am PC habe ich dann schnell herausgefunden, dass das ein bekanntes Problem der Vollwellen ist. IcI decided to replace the old hollow shaft with new joints (Spidan on the outside and SKF on the inside).I had to rework the shaft. Removing the outer joint was a test of patience and strength. I completely bent a large puller and broke a small one. After destroying the ball cage, I was able to use another puller to remove the remaining star-shaped piece. Throughout the entire process, I kept the shaft securely clamped in a vise. After reinstalling the reworked shaft, there's no more roaring or vibration, but it feels like the shaft is unbalanced at lower RPMs, up to 2000 RPM.Could I have bent the wave when clamping it in the vise?
What kind of replacement shaft can you buy? It is absolutely necessary that it be a hollow shaft. Unfortunately, well-known manufacturers like SKF or Spidan only offer solid shafts. The used market doesn't look promising either, because what is offered there is simply terrible.
What can I do?

Best regards,

Last year, I replaced both drive shafts and their bearings on our Polo 6N. I used SKF parts. I didn't experience the rumbling noise you described. So far, the drive shafts have been working fine, so I can't relate to your experience.

Are you perhaps missing a balancing weight?

Hello,
With the new SKF shaft, the Golf was undrivable. It had extreme roaring and vibrations. After switching back to the old shaft, the problem disappeared.
I didn't see a balancing weight on the old shaft. I can only imagine that it might have been damaged due to being clamped so tightly in the vise.
Everything's a mess! I just ordered some Spidan products and I'm hoping they will help me fix things.

Regards,
Reuselkopp.

Strange. SKF products are of high quality. It's possible you received a defective product.

"Hi, I've also found information online about this phenomenon with drones and vibrations at full power. The waves that are built-in are hollow waves and are supposed to have a damping effect."
Best regards, Reuselkopp.

Hi there,
bist du sicher, daß der Händler Deines geringsten Misstrauens nicht eventuell irgendein Teil geliefert hat, wo zufällig ein SKF-Aufkleber drauf war? Sowas hab ich nämlich mal für meinen Cinquecento bekommen, da klapperte das Außengelenk dann direkt nach dem Einbau... Habe dann eine Ersatzlieferung bekommen, wieder SKF. Und die Welle war ca 1kg schwerer und sah völlig anders aus. Hat then it also works without rattling .

Best regards from Berlin,
Okay, please provide the German text you would like me to translate into English. I will only provide the translation.
