i was looking at rizbel's diff fluid change thread, and noticed what looked like a grease zerk on the sway bar. is it a grease zerk?

It looks like a fluid bleeding nipple that's used on brakes but what it's on is a mystery. Maybe rizbel should tell us.

Edit: I just found out what rizbel has subsequently said by looking on RealOEM.com but that nipple isn't a grease nipple unless it has a ball bearing closure, and it's called a bleeder valve.

That is the Active Roll Stabilization (ARS). I wouldn't mess with it until I find servicing requirement spec (what grease and how often).

if you're talking about the big black thing with "MWTM" written on it, it looks to me like the ARS component of the sway bar - this is the part that actively compensates body roll in corners

EDIT: was too slow... had opened the thread much earlier and it had no replies yet
