Re: Two piece driveshaft rebuilding

If your vibration occurs when:

1) Accelerating
2) A little when decelerating

And doesn't when at speed without load or is much less then you have a bad U Joint(s).

Therefore, before rebuilding the support, I would suggest that you give all of your U Joints a through inspection. Any signs of wear means that joint must be replace, which is not an easy proposition. This requires welding a good used joint onto the shaft and then getting it balanced.

One of the joints on my 901 was bad (single driveshaft). I could not find a place that could do the job at a reasonable price. I opted for replacing it with a new driveshaft with modern joints, which was cheaper.
