Just found this on a forum, looks promising
cranking and wierd noise while turning
Hi guys,
I'm new in subaru and I need some help here, I am getting some cranking noise from the DCCD in auto mode while turning.Does that means that central diff is going down and need to be replaced.
The car has 55mil but have no idea what has been done on this car becouse I bought it two month ago.
Thanks
I have the axact same symptoms with my sti... been to the dealer a couple of times about this and they say its normal... sure as hell dont feel it, but they say all the sti's with dccd does it and they have not yet had one with any complications.
Even though mine was on auto, people say it can happen in all modes. will keep an eye on it and try a drive with lock on me thinks
