English Axle - Diff Gasket
Silly question...
How do you remove the diff to change the gasket (leaking)?
I presume you just unbolt the prop shaft and the bolts around the diff and then it comes out? or are there other bolts to undo??
Thanks

PROP BOLTS
HALF SHAFT BOLTS (IN REAR BRAKE DRUMS X4 THAT HOLD BACK PLATE ON) THEN SLIDE HALF SHAFT'S OUT YOU MAY NEED A PULLER
DIFF BOLTS
THEN IT SHOULD COME OUT

I cannot remember which is which, but there are 2 types of english axle diff IIRC, one is like mine, and has the diff casing housing the diff and
removable as a complete unit. The other (Atlas I think) has a cover plate on the rear of the diff and this means that you can remove it in situ.
If yours is like mine, then I'm afraid you will need to pull the driveshafts out chap 
If I'm wrong I'm sure I'll be put right soon enough

Forgot to mention it, don't forget there will be oil pouring all over the palce so be ready! (unless it's all leaked out of course  )

All english axle have removable diff assemblies -- in the old days this general design of axle was called Timken Banjo.
To change the gasket the halfshafts have to be pulled out. Personally I would try a different approach first suck or drain the oil undo all
the nuts ( put the nuts in a safe place as they are UNF threads) then pull diff assembly out a as much as it will go. Solvent clean the flange as
much of the oil off as you can and try and inject an instant gasket product into the gap. Allow the sealer time to partly cure before
re-fitting the nuts, tighten the nuts in stages using a diagonal tightening pattern It may also be an idea to use some sealer on the retaining
bolts.
Also check the axle breather is clear.

I will try this method first. I bought one of the extra thick gaskets, so I guess if there is room, I could cut the top and fit the new gasket plus
add instant gasket as required. I will also check the breather.
When I bought my car it came with a haftshaft puller, so not the end of the world if I need to remove them.
Thanks

Regarding the different approach detailed below - Is it possible to remove the studs that hold the diff assembly (put two nuts on and then unwind)? so
that I can fit a new thick gasket (cut the top) plus the sealent?

The studs can't be removed they are welded in.

OK. I need to pull the half-shafts then.
