Must have been changed for solid at some point, as far as I know all manuals have the DMF. I changed the DMF on my Transit for a solid flywheel and modified clutch.

I will get under it later or in the morning and get some measurementsif you measure what the gap between flanges is, I will measure my 2001 petrol flange to flange tomorrow.
the sliding joint will take a little bit more +/- as long as it’s close.

By the way, my vibrating diesel disco 2 (auto) has the rubber donut. I did think it was to do with protecting the back diff from shock and this was confirmed by the great James Martin. So not sure auto makes much diff.
"The flexible disc absorbs the vibrations and the load changes of the drive train. All of the motor’s torque must be transmitted through the flexible disc before it reaches the wheels via the drive shaft and differential axles. The design of the flexible disc absorbs the shock and load forces, prevents disturbances in the drive train, and prevents harmful angular misalignment. This reduces noise and vibrations from the drive train."

I think your right.

So what protects the front drive shaft and diff?
It's a shame you can't tilt the engine and gearbox instead!
The fan angle would change a little but as long as the shroud is on it may not loose any efficiency.

That would cause the front prop to run at a steeper angle then ? My shroud ended up under my toolbox the first time I had to dismantle the front end of my RR I think and it's stayed there ever sinceIt's a shame you can't tilt the engine and gearbox instead!

Just been out and measured my props. 2001 4.6. front measures 765mm, Rear measures 985mm this is the gap that the prop fills will/may not be the actual length of the prop cos of the sliding bit.

Got under it this morning and working measurement from flange face to face on the brake drum is approx 990mm to the best that I could measure
Looks like it's getting worse
Yes.

Nice one , cheers for doing that will get on eBay and get one sorted and see what happens
Dunno, and James is no longer live on the forum to answer the question.
It's the same question for my 300tdi Disco 1 manual.
Maybe it is something to do with the dynamics of a diff that pulls rather than pushes. I do know, (I think) that both diffs are identical.
On the D2 I daresay the double cardan joint is a bit more protective but this is all really rather above my pay grade!
Fair point..That would cause the front prop to run at a steeper angle then ? My shroud ended up under my toolbox the first time I had to dismantle the front end of my RR I think and it's stayed there ever since
Is the lift all in the suspension or is it body and suspension lift.
Are you having problems with both props or just 1?
It may not seem extreme to the eye but there is a reason they make these extreme props.
I am not sure but the diesel has them to smooth it out a bit, cos them diesels aren’t as smooooth as a V8

Not on the manual. That has no rubber as it has DMF for vibration.
Only autos.
As said “I know nothing” ( said in my best mawel voice from faulty towers) about diesel p38
Lucky that’s what he has then
