Hi everyone.

Range Rover L322 V8 4.4 Vogue 2003 Model.
73k mileage - with all service stamps.
Lovely 2012 facelift + full colour change last year
- my pride & joy - but giving me a hard time at the moment!

I've been systematically working my way around my engine bay - trying to discover what on earth this noise is... what's broken... and how expensive it's going to be to put right?

Noise: High Pitch Whirring / Grinding / Dry Bearing kind-of sound.

Have replaced alternator / power steering pump.
Have disconnected 'Both' Belts and driven - noise still present (so nothing to do with any of the pulleys on the front of the engine.

Changed all fluids including trans / transfer box / diffs / engine / power steering (all fluids).

So now I'm t the point where I recognise it could be transmission / torque converter... but before I go down that road I would really like to know if anyone actually recognises this noise and advise on the appropriate action.

Just uploaded a video on youtube - would appreciate any informed comments.

Noise only happens when engine cold.
Only happens on take-off in 1st gear and much less in 2nd (auto ZF trans?.

I left it running whilst I washed it the other day - 30 mins of this before driving off.... no noise.

Many thanks for any advice.
Mark.

the use of a short length of hosepipe used to locate strange noises is a cracking method,
one end to your "best ear" the other wanders around to pinpoint noises..

used that idea for years,
bought a stethoscope but found it no better..

I use a 2' length of M5 studding with my thumb over the top held just in front of my lug-oil.
