Ok, here goes,
Identify which joint is in trouble, remove all circlips from bearing cups, they will be seized so a small whack with a hammer always works.

Place joint in vice as shown in pic, hit with hammer on prop joint, you should see the bearing cup rise from the yoke.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement002.jpg)
This is what you should see.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement003.jpg)
Flip the propshaft over & repeat the processs.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement004.jpg)
Part the 2 halves of the prop joint, you may have to remove sealing washers to achieve this. In this case, due to wear the washers had already fallen out
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement005.jpg)
Take the other part of the propshaft & place in the vice, repeat the cup removal process as before.

The cups should rise as before.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement007.jpg)
Flip joint & remove other bearing cup.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement008.jpg)
Inspect for damage, as you can see on this flange it is beyond repair. So replace as necessary.

You may find a different design of circlip, these can be removed with pliers & a hammer.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement010.jpg)
Clean all yoke surfaces, I use a rotating rubber block with a tube of sandpaper around it which fits perfectly. Emery tape is as good.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement012.jpg)
Try & use a good quality propjoint as the cheap ones don't last. (We do carry a more than comprehensive stock!)
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement014.jpg)
Remove all cups from spider joint do keep them clean
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement015.jpg)
Place new spider into yoke,
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement016.jpg)
Slide 1st cup joint onto spider, this keeps the needle bearings from falling out.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement017.jpg)
Place the other cup joint into the yoke & onto the spider, try & place spider half & half in each cup joint.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement018.jpg)
Press in 1st cup joint with an old socket until the 1st circlip groove is visible. Then fit the clip
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement019.jpg)
Make sure circlip groove is clean & free of debris.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement022.jpg)
Press in 2nd cup bearing & fit circlip.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement023.jpg)
The joint should now look like this.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement024.jpg)
Take the other half of the prop shaft & slip the spider in to the yoke. Make sure grease nipples are lined up with each other as this makes it easier to grease when fitted to vehicle.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement025.jpg)
Slide cup bearings onto spider as before. Making sure the spider is half & half in each cup.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement026.jpg)
Press in 1st cup with old socket, until circlip groove can be seen. Fit circlip.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement027.jpg)
Flip prop shaft over & repeat the pressing in process on 2nd bearing cup. Fit circlip.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement029.jpg)
Your prop shaft will now be complete. You may find the joints are stiff to move. Place the prop shaft over the vice as before & tap each yoke so the bearing cup moves towards the circlip. This will free up the joint.
(http://i281.photobucket.com/albums/kk211/mrmservices/Propjointreplacement030.jpg)
Refit grease nipples & grease joints as necessary. Refit to vehicle using new nyloc nuts.

Hope this is of use to anybody who has the same issues, hope this saves you a few pounds on repair bills
