Hi guys. I have just replaced the centre driveshaft bearing on my VZ and forgot to mark the front and rear shafts. I put them together randomly and have a vibration at 80-90 kph,
I pulled it back out and noticed it does have factory paint marks but if I align them, the front and rear triangular flanges look to be 180 degrees, (nearly) out of phase. Should I put it in like this or just align the flanges the same, realising that there are still three possible positions for this. Thanks

The "easy"way is to mark what you have now, and try the other two options, marking as you go. It's 50/50 if you get it right on the first go now...

That doesn't matter, the OP actually split the driveshaft which is different to just removing it from the car.

If you didn't mark the shafts before putting the new bearing on you'd need to get it balanced

180 degrees out? Do you mean 90 degrees?

The universal joint trunions (the triangular uni-joint holders) on the driveshaft ends should be in the same plane.

Google an image.

I put the driveshaft back in aligning the factory paint marks, with the flanges 180 (could be 90) out of phase and vibrations have gone. Just completed a 1000 km road trip and no problems. Thanks for your comments.
