I own a 1990 ford sapphire cossie 4x4 and was planning on doing a full oil service on me car, what I mean by full oil service is engine oil, front/rear diff oils, transmisson oil
but being this is the first cossie I have owned am kinda stump as the front and rear diff don't have any drain bungs that I can see, had a read of workshop manual and found for the front diff you take the bottom plate off but couldn't see how to do the read diff, possibly missing a page or 2, any help on this would be great, also am thinking about taking the engine out for a cleanup + freshenup but have never ever taken an egine out of one these.
I was thinking about undoing all the sump bolts, undo the gearbox and lifting it straight off the sump/front diff, does this sound like a good idea?

again any help would be appreciated
cheers
