As above fitted a white line rear anti roll bar few weeks ago, now a loud creaky sound from rear. Sounds like dry creak if you know what i mean, could bushes want lubing already??

Sometime ago a few people reported a similar issue.

It seems if the clamp is not fitted perfectly square and perpendicular to the bar, it distorts the bush and that leads to squeeks.

Realignment of the little bracket seemed to work - at least the pleas for help stopped.

My Whiteline doesn't, so its not an inherent fault, although someone mentioned that the polymer material had changed. Don't know if that is related.

Yes no lube came with it a new silicon i think, but not sure been fine till a couple of days ago.
