Mines no different clutch in or out. Engine just stops, no vibration, no EGR noise, but then that's due to BAS.

r u sure?
surely the bas map might have an effect on the egr when shutting down but not the clutch......  (another sleepless night)
so does that along with the kangarooing spel - shot clutch? (damn - just thought. I hope k9f isn't watching this  ) |

well that does it.....I'll have to get the wheels checked.
can't see it myself but I'll be very happy to find I'm wrong
thanks. |

its just I can't see that applying about of acceleration / load onto the transmission how this would affect the wheels to then generate the vibration (speed yes load I can't see)
you're right then thats a great result. many thanks. will report back once sorted |

One is apparently supposed to be thankful for small mercies. I just wish this small mercy had been a little longer. Only three days since.......
Now you're getting yourself in a tiz over other people's trucks. FFS if you see Caterham walking please don't give him a lift.
  If you go through life with your head in the sand....all people will see is an ar5e!!
Treat every day as if it is your last....one day you will be right!! |

yep was underneath last night and so far as I could see it seemed ok except there seemed to be a very small amount of vertical movement in the rear prop and a kind of creaking noise from the drum brake?
only very minor so it might well be normal but I wouldn't have expected anything? re labouring the engine I dnn't believe its that as on a flat it'll pull cleanly at less then 45. exhaust made a similar creaking noise (again no more than I would expect) and the heat shiled bolts at the bottom ok. - gonna go have a look at the other bolts in a minute. (damn - I thought Mal was looking the other way and I'd gone un-noticed  )  |

Hi,
Out of shape ... "labouring the engine" if I remember, land rover tell us that the engine is fine between 1250 t/min to 2000 t/min ... but what is good for consummation is mayby not so good for the engine ... Phil current : defender 110 sw 2.2 puma 2012 and 230.000km today and again my Range Rover VM2.5 engine from 1992 and 528.000km today. One ten 1988 to 1992 1987 BMW GS80 One Ten from 1984 to 1987 One Ten from 1983 to 1984 Serie 3 109 from 1980 to 1983 from 1974 Jeep CJ3B and CJ6 |

It seems you'll be chasing this vibrations for a while I'. Start with a good in depth service of the drive train but I have read back and seven a suggestion to check the balance of wheels which is. Good start |

I can get the wheels sorted but the very slight increase in throttle causes the problem which leads me to think its the drivetrain. also having now noticed just what great difference depressing the clutch makes on turning the engine of I'm thinking thats where the problem lies. ?

The simple thing to try is drop it down a cog while driving at the same speed [ie change down from 6th to 5th while maintaining the same road speed] and see what happens then. Try the same in other gears at similar rev range, try coasting at that speed too, try running the engine at those revs whilst stationary and in neutral. There you go, lots of things to try and then postulate over.
TBH I think that you rather enjoy having something, anything, to worry and then concoct theories about. Steve. Owned numerous Land Rover vehicles of all shapes and sizes over the decades.

I showed this to my wife last night and her reactions was
 "They have done what I did when we first got the Defender, they are driving to slow in top gear".
I will say no more. Don't make old people mad. We don't like being old in the first place, so it doesn't take much to  us off.

I always have the clutch out (ie pedal pressed) when starting and when stopping.
What noises do you get when switching off the engine with the clutch in? Rattling from the clutch area as the engine stops is a classic symptom of imminent driven plate failure (the loose spring problem that the Puma became famous for). It could also conceivably cause speed related vibration. Rattling from the gearbox may be backlash (which I think you said you don't have) or imminent adaptor shaft failure. Have you checked for evidence of a lost propshaft balance weight? You say that you have "very slight vertical movement" in the rear propshaft. You shouldn't really have any such movement, can you see what is moving? It could from your loose description be diff pinion bearings (ie rear flange moves up and down), rear propshaft UJ (rear end of shaft moves but flange doesn't), propshaft splines (shaft effectively bends in the middle, neither flange moves), front UJ (front end of shaft moves but flange doesn't) or transfer box output shaft bearings (front flange and handbrake drum move up and down). None is good, any could cause vibration and noises. I do worry that your Defender may end up driving you to the funny farm, and perhaps you aren't cut out for Defender ownership! There are only two things that can happen really with Defender noises/vibrations/defects. They get better, in which case no problem, or they get worse. If they get worse, they get easier to find and fix. Either way there's no point worrying. |
