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 

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......

and whats this bush that you mention inside the rubber dough nut??????

According to the Land Rover Discovery Parts Manual I have:

There are only two rear propshafts listed;
 
FRC8387 to VIN LA 081991 and V8 from VA 710669; from VA 51628 To VA 558898 - This is the one with the two U/J's fitted.

FTC3705 from VIN MA 081992 to TA 199999; from TA 700000 to VA 710668; from TA 500000 to VA 541627 - It also gives a note that says this part number is used on the following VIN numbers - Except for V8: VA 710669; from VA 51628 To VA 558898

The bush goes inside the hole in the end of the propshaft. When you take the proshaft off there is a spigot on the flange connected to the diff. This spigot goes into the propshaft & into the bush, this prevents vibration at that end of the propshaft.
The bush part number was STC2932 but it is now included in the Propshaft Coupling Kit STC2794.

I don't know who told you the gearbox's were different lengths, but that's not true, though I have found the front props to be different length between the V8 and TDi, for some reason.
