How to locate differential noise? Part 2

[markus_74]

I just try change my oil to 140 but it is noise still there and I think louder and now it feel drag heavier, so I change back again to castrol 80-90

The sound from my rear car is like howl but very low like sound of typhoon or fast wind, the loudest is at 40km/h but at the speed 40km/h the noise is become faded or disappear because may be the engine sound louder shadow it.

I still think it is diff or tire bearing.

Sorry still can not reply at the same thread, may be in use tablet phone and not laptop? Or the zone system prevent me to do that?

Thank you
Markus

Try to corner hard going 30-40 kph if its wheel bearings the noise will become louder as that wheel is put under more weight and almost disappear in the other direction. This will find which side has gone also. If its diff bearings it will be present in most conditions. Only a rough test but should shed some light on the noise.
