disconect the front prop stick it in 4wd and see if you can apply some strain to the prop and see if you can recreate the sound

does it do it under 10mph or not ?

if you hit snow and it has gone this to me would mean that the tyres/wheels are causing it. have you had the off set checked or used a second set of wheels on when did it start doing it

as you would still get the noise if it was something like the transfer box as it has to work as hard or in some cases harder

have you tried it in mud ? an is it the same

if you hit snow and it has gone this to me would mean that the tyres/wheels are causing it. have you had the off set checked or used a second set of wheels on when did it start doing it no same old tyres.....and TBH the noise is too loud for it to be just tyres I think.

have you tried it in mud ? No - same probs as above, only kicks in around 25-30mph and I suspect would behave same as on snow, i.e. no noise... an is it the same

see above....thanks for the suggestions, everything helps....

ref the "goes away on snow" thing, I am assuming that the slight slippage, even in 4WD is enough to take the strain off whatever is causing it....

it makes it easier for the tyres to slip and not wind up but the forses are pritty much the same from the transferbox as it will try and drive the wheels

idea have it at a rolling test garage with a pit all wheels on a roller some rollers have adjustable friction some one under it or a mic and see where the noise is comming from

it could be the caster angle which is causing it
