3.9 V8 rear rubber dough nut
disco-v8:
ok simple one....
im on my fourth one now in a year, and the last 3 are in the last 3months :evil:
i have no idea what ripping them to shreds but its getting exspensive now!!!!!!
i want to convert my rear prop to a 200 series one, but as mine is a auto, im not sure if ill be able to get a short one off a 200series...... did they do an auto on the 200series????
if not is it posible to cut and weld the UJ part onto mine????
P.S. what about a range rover classic???? they had autos and smae chassis as a disco so will they fit????
thanks

It is possible to change for an ordinary propshaft but you will need to change the flange on the nose of your rear diff as the doughnut version has three holes, where the UJ version has four.
Not a huge operation as I understand it and a good one for refreshing your pinion bearing & seal at the same time!

The rear propshafts are the same on rear, it's only the front that's different on the V8 auto.
So you can use an early Disco prop or a Rangie one. ;)
One thing with the doughnut, have you only replaced the rubber or have you also replaced the bush inside the propshaft that the flange spigot goes into? You may find that if you replace the bush as well then it won't go through the dough nuts quite so fast.
Also, when I fitted a Rangie rear propshaft to mine, because of the +3" lift, I found I got some vibration from the U/Js and ended up going back to the original propshaft. I could go back to the Rangie one now I have the Scorpion cranked trailing arms as these can be spaced to eliminate the vibrations caused by the lift. ;)

are you sure there the same lenght as the auto box is longer than the manual so i would of thought the rear prop wud have been shorter, and the front longer......
