Ayc & Differential Problems (help)

[samm-tt]

I recently bought an evo IV November of last year and got caught with the ayc light trick , changed the differential due excessive noise humming and whistling replaced it with a evo V also the complete ayc pump still hearing loud grabbing noises when turning changed oils and bled ayc system twice any suggestions ?:cry:

How have you bled the system?

 

[samm-tt]

The mechanic used a diagnostic tool software an through the two bleeders .....

Any suggestions?

Is the AYC light still on or has it gone out since the diff was changed and AYC fluid bled and changed?

 

[samm-tt]

Sure all oils were changed the ayc light is off we also changed the complete pump from an evo VI still hearing that grinding sound when cornering ..............

 

[Matt-evo-v]

I would be inclined to think that it is not the rear diff or AYC itself then mate.

Possibly the diff bolts. Not entirely sure on the symptoms of this, but sounds familiar. (might need changing).
