This next hint, is kind of new to me.
I don't know whether anyone else has experienced this, but I have, but only half as bad as what I'm about to explain!
If you take a look at you driveshafts, you'll note that they are in two parts.
Connected by long alan key bolts, of which, are connected together by small metal plates. Pictures to follow. I've had one of these bolts work loose on the drivers side.
And in turn, the next one along has has loosened. This makes the metal plate flap around on the subframe. Noisey! 
BUT, for the first time, I saw this happen on the passenger side.
One bolt worked loose, then a second, and the metal plate literally cut a hole in the side of the gbox! 
The most shocking part of it all, is the garage that
'Rectified' this, put in some replacement bolts. But failed to realise that ALL the gbox oil had emptied out the hole! So when the car arrived with me, there was NO oil in it at all! and a hole in the side of the gbox! And that was 'Fixed'! ](./images/smilies/eusa_wall.gif "Brick wall"){kind=small}
So, to save all this trouble, please all go out your way, to occasionally jack up the car, and check all these bolts are nice and tight.
Like I say, I'll add piccys tomorrow to better explain what I mean.
Wishing all 2's a long a prosperous life
