noisey whine???

[hookie]

hey guys first time poster, a lot of great stuff on here tho,

my Y60 has a whine which starts at over 50kph and in 3rd and continues to get more high pitch as you go through the gears, it stops upon deacceleration and coasting and doesnt appear to happen in 1st and 2nd, i also cant nail it down to either the diff or gearbox i have checked for tail shaft and UV play and the backlash doesnt appear to be abnormal in the diff also no metal shavings in any of the oils, sorry for the novel any ideas?

no sure as its nissan but sounds similar noise to when my toymota transfer case went (noise was caused by hardner being worn off the gears)

Id say diff, my work van doing the same thing, cant hear anything untill bout 50k and in 4th and 5th

haha nah its usualy hard to hear a toyota driver from the towed vechile behind you ........ but jokes aside i think dropping the diff might be the next step. does anybody know any more quick tests to check to narrow things down?

cheers for your help guys

Take the rear drive shaft off run it in 4wd see if it still makes it

Keen to try this test but wouldnt the transfer case spew out oil once the rear drive shaft is removed?
