Disco 2 Rear anti-roll bar

I keep breaking the tie-bars on my rear anti-roll bar! I go round a corner, there's a massive bang and when I look, the tie-bar ball and socket has popped out! A quick check last night and I noticed that the arms of the ARB are not even. One is really high compared to the other.

I have ACE on the car so I assume the long arm hydraulic part has turned on its bush. Can I just take it off and re-assemble it in its correct orientation?
