    Exclamation 06 STI centre diff grinding? Help!

    So I took my car in to cantaur Subaru in Calgary (Canada) because my centre diff has been binding and making a grinding noise when i take sharp corners. I told the people inspecting it they had to drive it in circles in a parking lot to hear it, that way all wheels would be touching the pavement, but instead they put it up on a lift and turned the wheels from lock to lock... which showed them nothing because that does not cause the differentials to slip.. so they told me to replace my transmission which could cost up to six thousand dollars... does anybody know what the actual issue might be? like I said, grinding noises from the middle, possibly rear end. ??? (car is a 2006 wrx sti)

    I found this video on youtube, my car is doing exactly what the car in the video is doing. thanks guys!

    You dont have to replace the whole transmission. They can remove and replace the viscous coupling separate.

    Would cost about $1k parts and labor, or less....?

    I wasn't planning on touching the transmission. nothing is wrong with it, the dealer was just trying to rip me off. i have heard that faulty ABS sensors can cause the centre diff to bind like it has been doing. But my centre diff may be too far gone for that to fix the problem completely. even when the dccd is on open it makes some noise. what do y'all think?

    Oh sorry, my reading comprehension sucks. You have an STi with DCCD. Not a WRX.
