Finally solved the noise in the front end of Rachelle's PT.
Went at all angles in the search for a fix. New lower control arm bushes, sway bar rubbers, the list goes on.
Had some spare time today and pulled the front end apart again looking for a fault.
In the end it was the augmentation springs on the pads!

On the left hand side they had worn out and were letting the pad rub on the caliper. Drama was you cant buy them seperately, they come as a part of the pads from Chrysler, after market pads don't have them included. Well the ones i fitted a few months ago did not.
