My XC90 has recently completed a return trip to Aberdeen and returned over 36mpg, without any hitch so I'm very pleased.

Whilst away, I noticed that when on full right lock and accelerating hard away from a junction you hear a horrible grinding noise which stops when you straighten up and ease off the acceleration.

When driving normally all appears ok, but I just had to accelerate hard in a straight line and heard the same sound.

I've been underneath and can't see any leaks, looseness, or feel any play anywhere (Needs a new drop link on nearside though) I recently fitted a new top engine mount and new torque mount to front of gearbox.

Anyone got any suggestions as to what it might be and how to fix?
