Axle wine vito 120

[zenman63]

Hi, I am getting a wine from the axle at about 70-80, when you come off the power it is less.
I will change the oil first to see if it helps, no leaks and all clean, just done 40k.
Question is what oil and quantity?

OEP 75/90 and about 1.5 ltrs

Don't you mean what vintage oil?

Well done the oil change, the plugs are Very tight 14mm hex needed a bar on them to undo.
Very dirty oil at 40k but changed it to Mobil 1 fully synthetic 75w90 and the
whine has gone.
1.75L
Well worth doing in any axle.
