OK - all I can think of is to try and work out where it is statically balanced.


What I suggest is


1) Wait for other advice! (EDIT - like the advice given whilst I was typing this)


2) Remove the whole propshaft.

3) Make a temporary support for the centre bearing - screw it to a block of wood - support on bricks - whatever

4) Now if you think that was bad - here's the tricky bit. You now need to try and support the other ends of the propshaft. I'm thinking something like lathe centres - or other bearings...

My point is that you need to be able to spin the propshaft quite freely so that you can see if it favours a particular point or not.

Static balancing is achieved when you spin something and it stops spinning at random positions - if it always stops spinning at the same place then it is not statically balanced.

Q:-

Why is static balancing important?

A:-

You'll not achieve the more complicated to achieve dynamic balancing with out it. It is the first and important step to balancing the shaft.
