Unknown Vibration
Chaps,
I seem to have picked up a vibration from underneath my 90 (200tdi). I can feel the vibration through the floor while driving, but it is not there all the time - maybe only occurs 2 or 3 times in a 10 mile journey.

It doesn't seem speed dependent as it occurs at 5mph or 30mph. I have checked the propshaft/UJs which seem fine, has anyone got any ideas what it could be?

Many thanks Thumbs Up BORG - Bucks & Oxon 4x4 Response Group

Did you take props off to check them for play?

is it engine speed related? Cheers

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.

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.

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

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

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. Very Happy Very Happy I can only assume it was sending a vibration down the chassis that I could feel through my feet.
