Default 2015 Sti popping and hopping when turning

Hello everyone,

I have a 2015 Sti with 57k miles on it and I seem to be in a need of help as my Subaru dealership is confused on what is going on with my car.

The symptoms are usually when I first drive my car and turn the wheel left or right and start to move forward or backward, I will hear a loud pop sound. Then intermittently the car will hop around as if you are driving on 4low in a 4x4.

Subaru has had my car for about 3 weeks coming on 4 weeks now.

They have replaced both front axles, top hats on my struts, and I even got a brand new transmission.

The car is still making the noise and I want to see if anyone else has dealt with this.

Thank you for anyone who can help.

If you put the DCCD into “Lock” it will do exactly what you’re explaining.

I've checked the DCCD as well and it's set to auto. The only time I touch it is to go auto + in the slippery weather and auto - in the summer.

You've ruled out front axles/front diff.

Suspect drive shaft joints or rear differential.
That model has a Torsen rear diff and it is possible you have an issue/failure in the diff gear cluster. I would drain the rear diff and see if you have gear teeth in the oil.

I would agree or it could be an electronic issue with the DCCD.

Rear diff and driveshaft were all inspected and fluid changed on the rear diff showed no containment. How would one test the DCCD?
