Disco 2 Rear prop rubber coupling question

As i had to remove the rear prop for diff seal change i have ordered rubber coupling set for the prop as well. The set also includes a bush which seems a bit different. Should i try to change it as well or just leave it and change only the rubber coupling?
I have tried to attach photo but it does not work..

Do you mean the spigot bush? If so, its a swine to remove. Took me about an hr with a cold chisel. Id leave it well alone unless it looks knackered. Is it a genuine donut or decent quality? The cheap one i fitted never balanced right. Fit bolts exactly as they were on refitting it

It is a GKN kit. The old one is also.

GKN one should be good. If you can find a broom handle or something that fits inside the spigot perfectly, you can use grease to hydraulically press it back out. It didnt work for me though! Best of luck

I think I will leave it as it is. It looks something completely different what I have in the prop. The one I got in the GKN set has rubber inside, mine has a metal (maybe copper) sleeve and rubber is between this and the outside wall of the spigot. The outside diameter is also different (mine is bigger).

This one ?

Yes, this is what I got, but I have different in the prop. See photo.

So, those whose rubber is failing after a short time, did you replace the spiggot ?

Sorry maybe I was not clear.
I had oil leak at the rear diff pinion seal so I decided to change. For this I have ordered flange kit and already changed seal and put a new flange on. The original centralising ping looked good and I put it back.
As I had to remove rear prop I also decided to renew the rubber coupling so I have ordered a kit including spigot.
What I do not understand why my spigot (which is in the prop) has a metal insert while the new GKN one does not? Maybe I have a different prop already changed by previous owner? I do not want to remove (chisel out) the original one until I am not sure the new one will fit.

Ah I see, sorry, Ive been reading a few threads on the rubber doughnut replacement.
