I bled my own AYC rear diff.
IT CAN BE DONE.
I fitted a new diff so I started from an empty diff and reservoir.
Put the car up on 4 axle stands,
Open bleed nipples, both of them, and pour in ayc fluid to the reservoir.
When the fluid starts to come through the bleed nipples, close the bleed nipples and attach a bleed hose to the left nipple. ( a piece of tube, similar to bleeding brakes)
Start the car open the bleed nipple, put it in drive (I have an auto).
turn the steering full lock to left and then full lock to right , do this a few times, you will hear the pump start to work when the steering is moved each way. After a few turns each way of the steering wheel the air is pumped out and fluid keeps coming through.
Repeat this for the other nipple, till all the air is expelled, then tighten the bleed nipples.
I then took the car to my mitsy dealer and asked him to check if my ayc needed bleeding, he attached it to the mut 11 and proceeded to bleed. He said the AYC was fine, with no air in it, he said if there was air in it I would have heard a grinding noise. I told him that I had bled the system myself with the car up on axle stands, and he said “well done, there was no air in it when we checked.”
