I don't normally drive at a constant 130kph but the long drive down to Le Mans and back was tightly regulated by the threats of the Gendarmerie so I was hardly ever above of below that speed.
I've noticed quite a loud whine that I think is coming from the front of the car at this speed (well, actually at any speed, but slower it is quieter so not very noticeable and faster it gets drowned out by wind and engine noise).
Front dif oil was changed recently - so I'm wondering if the new oil has brought on the noise. It is road speed related (i.e. does not matter which gear I'm in, the whine frequency relates to road speed)
Any comments or other ideas what the cause might be. If not I'll get the oil changed again (to a different brand) and see what happens.
