I have only read of problems when re-using an old propshaft. A new one should be perfect.

Are the u/j's correctly phased to each other?

On that note: are your cv's correctly phased/"clocked" or even individually assembled correctly?

What's the history on the propshaft?

I had vibration with a supposedly rebuilt shaft. In the end I dismantled the the spigot shaft and bushes behind the rubber donut and found it had not been touched. A good clean, some oil lubrication and reassembly 180* rotated solved the issue. Might be worth a check, even on a 'new' shaft?

My propshaft has been “refurbished “ ... so I thought. I took it to some propshaft dudes in Sussex along with a new donut but I think they did a crap job.
I have removed the propshaft and there are no vibrations. It’s lovely. So It will be a new one come pay day and laser line everything up and hopefully that will be it.
Keep you posted.

Laser shmaser...snake oil from across the pond IMO, trying to re-use worn out propshafts and get them vibration free.

The entire drivetrain does not sit on one axis anyway, its all angles and offsets, so there is nothing to "align", just the distance between the prop flanges needs to be settled so that the u/joints (and the donut) aren't in tension or compression.

Best achieved by driving a little way with the front diff mounts slightly loose, before torqueing up iirc

I had this exact same issue. Easily sorted by putting a large Jubilee clip around the prop shaft about two thirds way towards the front of the prop shaft, tighten it , go for a drive, if it`s worse rotate it a bit and try again. Keep doing until you "tune " out the vibration. It is in effect a balance weight.
Good luck.

Arun I also have vibration, did the front diff thing today which helped a bit then removed the prop, was like driving a different van I could not get it to vibrate at all at any speed, sound was a lot better too :mrgreen: , have ordered a new slider prop from Bricky today and the correct nuts, I had these fitted which were a pain to remove....

Reason for the new prop is the parts for the refurb are about £90 posted, about £100 for a local prop place to fit and re-balance, old prop worth about £100....new prop £352 + £12 postage...seems like a no brainer, may still need to be aligned but at least Ill know the prop is good :mrgreen:

if you take your old prop to GKN Driveline at Leek it should be around £150 for them to refurbish it properly, worth bearing in mind if you ever find yourself on the road in the area or passing, they turn them around quick
Other prop refurbishers are available around the country, anyone with good experience of any should post up for the benefit of others

forgot to say they won't do 1.9 petrol non donut props though as the trunnion joints are cinched in place, by the time the cinches are machined out there's no material left in the bodies for the circlip groove to be remade, or to recinch, but there are very few of those very early props still floating about
