hello, first time posting here .am gm mechanic but doing 2004 engine re & re for overhaul(machine shop is rebuilding) , on an all wheel drive 2004 e240 6 cylinder gas engine. took engine out and can not seperate the front differential from the oil pan . I have taken the intermediate shaft that goes
thru the pan , but the diff will not seperate. any ideas,anyone been there.
this car only has 50000 kms on it . was a leased unit and never got much TLC.
Engine getting rebuild rebuild because it blow smoke out the exhaust like crazy at time when accelerating. i think the rings are stuck . thanks

anybody, its a c240 by the way.

does anybody here know anything on these frt differentials.? also what type of fluid will it take to refill it ? and how is that done? thanks
