Did you take props off to check them for play?
is it engine speed related? Cheers James 110 2010 XS Utility 130 2011 M57 bespoke Camper 90 2010 Hardtop 90 M57 1988 Hardtop |

I don't think it is engine speed related as it occurred when I was coasting at 5mph and also when driving at 30.
I didn't take the props off, only looked for play as attached to the vehicle. BORG - Bucks & Oxon 4x4 Response Group  |

^Just to make sure we're on the same page.
He means engine speed (RPM), not vehicle speed... Solved the bowel problem, working on the consonants... |

Vidrations on a Defender can be a nightmare to diagnose.
Wheels out of ballance.Usualy happens at certain speeds,above 40mph. Wheel bearings,could be this,as you can feel it at all speeds.Check by jacking each wheel up & gripping tyre at 12 & 6.then 9 & 3,and shake the wheel. If there is movement at 9 & 3,but not 12 & 6,then this points to swivel bearings. U/J's as JST said you need to take them off to check properly. Loose wheel???? Probably not,but I have seen it before. Marc. |

Yes, 5mph was at idle and no rev counter on a Tdi for 30mph but not idle! And thanks Sharkey/JST - I'll check soon and post an update. Thank you BORG - Bucks & Oxon 4x4 Response Group

I had a vibration under my 90 Td many years ago at slow speed or coasting to a halt, turned out that the handbrake was binding. Stripped and cleaned it out and was all good after.
Could be worth a look. 2005 Td5 90 XS Steve |

Handbrake tends to snatch at those speeds, 5mph. ESP after a run when its hotter. Not sure I have had vibration from it.
Ujs unlikely at 5mph. In fact will give it some thought as not sure at such low speeds. Other than wheel nuts as ^^^^^ Cheers James 110 2010 XS Utility 130 2011 M57 bespoke Camper 90 2010 Hardtop 90 M57 1988 Hardtop |

Finally got round to having a look at this.
I changed the engine mount at the weekend and the vibration seems to have gone away.  I can only assume it was sending a vibration down the chassis that I could feel through my feet.
