I work at a GMC dealership and had a Ford Ecoboost driveline the other day. Can someone please tell me the proper way to clean a front diff? We tried taking off the front diff cover but there is not really enough clearance to pull all the bolts at the top and apply silicone. Is there an easier way to do this? In the end we just sucked out the fluid and replaced it.

 

I did the same as you.

I looked for a cover with a drain and fill holes but could not find one.
