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

How sharp of a turn?

I can't make "U" turn because whole car is shaking .
While turning 90degree there is a squeaks(cranks) coming up from below and rear inside wheel(left turn -left rear wheel) is lightly spining .the DCCD is set in auto mode.

Always keep it in auto unless going down hill and you want 50-50 awd. Subaru made a big mistake by putting that feature in the sti. it hurts the car using it when going slow and in turning situations.

The DCCD manual settings really weren't intended for everday driving. For snow and gravel though, it is a very useful feature. Saying "don't use it", I'm assuming you mean "use it for when it is intended"?

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.

Either leave it in Auto mode, or apply the E-Brake one click while making sharp turns at low speeds.

If you throw it in open it reduces it a ton. Its all about the different wheel speeds and how the dccd forces the wheels to spin at closer speeds to each other depending on the setting. If you have it open it will allow more of a difference between wheels allowing you to turn without the tires squealing and the car hopping like a 4x4 pick up does.

I heard only 07+ have this problem with the torsen center diff but it might be all STIs. If I am making a quick U turn I pop it in open and it doesn't happen anymore. Also full lock is great for deep snow.
