Grinding noise VT commodore

[Lucas_125]

Hey guys,
So I've got a 98 VT Commodore which I've had for almost two years now and there is a grinding noise whenever I accelerate especially when going uphill but it happens all the time when accelerating usually around 2000-2500RPM, I think it may be the diff but does anyone have any other ideas to what else it may be?
It has been doing it since I bought the car a year and 9 months ago and it's definitely not going away.
Any advice would help, thanks.

Mine was doing that. I noticed the bolts holding the differential were loose. I tightened them up with a spanner and now its smooth again.
