XC90 T6 prop shaft centre support bearing

I was getting a ticking noise when cold which means the prop shaft U/J bearings are on the way out. Changing the front and centre U/J bearings is simple and can be bought off ebay. I also want to change the large rubber support bearing on the centre of the prop shaft. I have the shaft off and have split it in two halves. Question is how do you remove the rubber support bearing from the shaft please? The rubber support bearing appears to be pressed on but the end of the shaft is a larger diameter than the internal diameter of the bearing. Does the end of the shaft also come off and if so how?
Thanks in anticipation

I am reasonably sure that the center bearing is not replaceable. Colorado Driveshaft can supply a reasonably priced replacement shaft.

Thanks but Colorado drive shafts are a long way from the South of England.
You can buy this support bearing as a spare part and I can think of no reason why Volvo would make a prop shaft that had a bearing set in the middle of it which could not be removed. How did they get it on in the first place?
I have handed it over to a garage to have a look at it with all their pullers and presses.

On the XC70 recently discussed it was learned that some prop shafts are welded. The only way to service them is to cut them, remove and replace carrier bearing, reweld and balance.

It is possible your prop shaft is a similar design as the XC70 discussed. Without seeing more pictures of the end and side views of the end it is hard to determine if your prop shaft has a nut and circlip holding it together as some Volvo prop shafts are constructed, or if your prop shaft is welded.

Keep us posted and put up some pictures. Interesting and helpful topic.

Interesting. Mine has no circlip or nut holding it in place but I cannot believe Volvo would weld the end plate on there by making the centre support bearing non replaceable.
I have sent an email to Colorado drive shafts to ask for some advice even though they are on the other side of the world to me and I will keep you updated.
