Noise from wheel bearings or differentials?
Hi guys,
Get a humming/whining noise when accelerating, happens at speeds over 60 km/h - and I know from reading on this from that the usual suspects are the wheel bearings or the differential.
But is there any way to tell which it could be, the diff or the bearings? Any different 'characteristics' of the noise that could identify either/or?
Thanks!

Recently bought the car, and not sure if the PO has changed the fluids. I may change the fluids to be on the safe side.
But the tricky question is - how do you differentiate a whining noise caused by the differential from that caused by wheel bearings?

Bearing noise typically changes with loading on the bearing - like high speed cornering puts more side load on the bearing. If it gets noisier when cornering chances are a bearing is going out. Differential usually exhibits noise right from the get-go (0 MPH..)

Then, getting Diff. + t-case + transmission fluids changed. Let's see how it goes.

How old are your tires. Tires make sounds like a bad wheel bearing. Check your tires first.

if it was the wheel, wouldn't the noise be non-stop regardless of foot on the throttle?
getting wheels balanced and checked anyway.
