"A" looks OK, but "B" doesn't, am I reading this right?
Been getting bad vibration around 70mph, checked all the usual suspects. Took the propshaft off, and it looks out of phase to me.

I can see what your saying. It's 90 degrees out at the engine end. But I would say why has it all of a sudden appeared?
Have you had the slider out for any reason? Some are master splined..... But again why has it just started doing it? I'd check the bolt that
hold the horse shoe in place in the middle. Where you'd strip it to replace centre bearing. Has that come loose? Maybe it's me, but it
looks wonky.
Yes you are reading it right, the left hand half of the propshaft has the UJ's out of phase.
Is there a splined/sliding coupling on the left hand of the shaft? If so can you take it out and move it by 90 degrees?
Hi
If you moved the splines before or are going to move the splines to put it in phase
Then you will need to get the propshaft balanced
if you move just one spline its enough to put the propshaft out of balance
and hence the vibration,
That is of course that bearing & CV joints are ok.
Good luck

stevio73, it's always done it, just been too busy driving, now the cars in hibernation I can get on with the niggling bits 
MokeRJ, yes it is a sliding coupler, I'll see if it has a master spline or not. I am going to have a TRT fitted so the phasing can be put right,
now that I know my suspicion is correct.
Thanks chaps.

I notice 'witness marks' on the right hand shaft, (the silver stripe)
what has been rubbing on it?

My understanding is that to have perfect phasing, you would need 2 pairs of UJ's.
So as this is the standard Sierra layout, the phasing is not perfect , but in normal use close enough and with a little compensation provided by the
centre bearing deflection, acceptable in production.
So it may be down to balance, or your application?
I'll try and check mine later for sanity!
Looks OK to me. Have a look at this escort prop looks the same

Dunning and Fairbanks in Leeds. I shall be ordering a shaft later this week now I've finished dilly dallying deciding on what to run.
Had my propshaft made by bailey morris with the slider at the engine end. I told them that was how i wanted it.
i too have bad vibration, from about 45mph though. What does phasing mean with regards to a propshaft?
Cheers

Which end have you got the slider? Mine is on the engine end, but Bailey Morris say it should always be on the diff end, could it be flexing, whereas on the diff end it would possibly be pretty rigid?
Another thing said on the Bailey Morris site is that the centre bearing should be used to put slight pressure on the gearbox output shaft!
