Has it stopped the up down movement in the drive shafts too?

Be a devil if all those diffs have been replaced at great cost to the owners just for the sake of 1/2 pint of oil wouldnt it?

The up and down movement is still there albeit only slight. I am amazed that such a small amount of oil can make such a difference though.

Looking at the unit I can't seem to locate where the filter fits. I'll have a look later today I think. 2010MY 2.2 e4 (gone but, not forgotten)

This thread might help?

The filter that you can replace is shown below 6A631, to change the other filter you need to remove the Haldex unit.
