I currently own a 4Litre Prado GXL 2004 model -Auto 4 speed and have noise sounding like a diff noise at 100 to 110K.
It is quite noticable driving at 110 km on expressway-concrete road and slightly less on bitumen over concrete.
I can slide the box into neutral and noise disappers but comes back when slide back into gear and under load.
I have had the service manager on a test run and he can also hear the noise but we could not exceed 100kph at the time.More noticable at 110 and less at 115.
His suggestion is that if I want they can pull the rear diff pinion out and replace it but the noise may still be there.
Does anyone have similar noise prob or am I too pedantic with my unit.
Would like to hear from other Prado owners with similar miles .
Regards
Wayne

I have exactly the same model (4Litre Prado GXL 2004 model -Auto 4 speed) and don't have this problem at all. however i note that this may be the same problem that is referred to at http://www.lcool.org/technical/120_series/vibration/90hz.html

Drew,
Thanks for the update. My Prado is a build date of May 2004 so has the updated components fitted. I dont think that is the problem but still looking for answers.
It is very noticeable at 110kph but does drop off if under 100kph.
Really annoying not knowing what it is
Regards
Wayne

Tyre whine can sound like diff whine. Are you still on the original tyres?

Cheers

Still on original tyres so dont think this is the noise.
Thanks
