droplinks

Hi All I have just spent a day replacing the rear coil springs on a 2000 ML320. I noticed that the anti roll bar drop links were not fitted/missing, is this common, a standard fit or should I replace them, will the handling be greatly improved? It doesnt look like thay have ever been fitted...

Been running over rough ground over the w/e and noticing the annoying noise while moving at slow speeds - pretty sure it's the droplinks but while i'm there I'm going to replace the swaybar bushed etc. Anyone on here know the part numbers i'm after please so I can get them from MB ? thx

I changed the ARB droplinks in summer last year but the car just failed its' MOT on them. I'm a bit disappointed because I was confident that the suspension etc. was fine. Should I get another pair like this? or alternatively do any parts suppliers on here offer the same?

I have read on other threads about the tendency for these to need replacing. I have an occasional 'clunk' from the front suspension on my '00 E320 CDI Estate, and suspect this is likely the required fix - there is no play in otherwise sharp and accurate steering. Does anyone have any...
