Yep and it's not the exhaust manifold - I checked that out thoroughly. I reckon that given the age of the prop shaft that's got to be where the noise is coming from.

Went down the shops again and it's a lot more "chirpy". When I think back a bit - last week what sounded a bit like a staccato slipping belt was evident for a few km's along the freeway so I'm about 100% convinced the front prop shaft is about to explode in a blizzard of shrapnel 'n stuff.
It's done well. This is the original at 375kkm's.

Maybe the harmonic balancer - mine chirped when in it's death throes

Get under it and have a look. Move the shaft laterally.

If that's the original front shaft Markf at 375k I'll eat my hat. I'm on my third and at 220k. 70k of which is mine.

I don't think so - the chirping is road speed related and not engine speed related. The vibration especially happens at around 80kph in fourth or fifth gear.

What about your version

There is an almost non discernible amount of play there. After a short drive the centre of the double cardan joint is quite warm to touch - no hot but quite warm. There's a bit of rotational play there too.

I got the car at ~320k km with a VERY complete service and repair record - service book stamped as well as receipts for everything right down to a servo in Seymour changing a headlight bulb. There's no record of a new prop shaft there so given the completeness of the service and repair records I _assume_ that I'm still on the original. The previous owner spared no expense and if it needed doing he got it done pronto I reckon.
I may be wrong of course and the prop shaft may have been changed along the way but the records that I have don't show it.
