I can drive around @ 25mph in 5th, hit an incline and you can hear the flywheel rattling around if I don’t change down. That is amazing for a vehicle 2+T that can do over 100 in same gear.
Made a big difference to mine when I replaced it. People often comment on how smooth and quiet my car is for an old diesel. I am certain the DMF contributes to that and glad I didn't convert to single billet.
Only in the situation as stated. They are designed to smooth out the power strokes from the engine at low RPM in high gears in slow moving traffic. To prevent transmission damage.

If I get real stuck (cheap) I could just weld mine up. Rather not though.

Probably helps crank absorb vibration too, which seemed a concern when they designed it.
Yes, although I can confirm it gets loud at all revs when f***ed. I drove around in ear defenders at motorway speeds just before I bit the bullet and replaced mine!
That's what the bloody great resonance damper on the front of the crank is for.

Mine should be fine then. I can hear play in it but not noisy

Dampening where it bolts to the transmission must smooth it out bit shirleyThat's what the bloody great resonance damper on the front of the crank is for.
If on every power stroke the inner is hitting the outer what can you expect.
DMF is for damping out engine power strokes that pass through the drive train into the transmission.

The DMF? Always has play. Moves about a tooth easily. Then you can put your hand on a new one and twist against the spring pressure and move it maybe a few teeth. On a knackered one when you twist against the spring you can twist maybe 9 or more teeth without hurting because the springs are weak.
You notice it a lot on hills when tired. Using engine breaking the car sort of lurches rather than just descending smoothly.

Only issue I have is lack of tank pump fuel so you have to take a good run up - 2,400rpm + to make a hill.
Something vibrates at 55mph, hoping it’s just UJ. Could be hub bearing or front calliper sticking.
Thing blooming shifts is all I can say, thought they were supposed to be slouchish

No springs on a Transit DMF it's a bonded rubber sandwich and cannot be moved by hand. When it starts to fail, it clogs the starter motor with black dust and rattles like feck at idle.
I was told that it also absorbs shock loads from clumsy gear shifts as well as smoothing engine output.
A rear wheel drive Range Rover sounds an utter waste of space.

Selectable 4WD and free wheel front hubs would be nice.
You need the Series section!
