At the moment, I am trying to pull the diff out, to change the gears,
and to repaint the pretty new scratched Spyder frame. All this with
the body off the frame.

I've the CV conversion, and cannot get the diff outputs to free up out
of the diff, and one of the CV shafts is not releasing from the inner
joint. Are the shafts captured on the CV joint? And are the outputs
fixed in the diff? If so, the top mounting bolts don't pass out the
bottom, and the diff won't slide out the side....etc. Maybe a
torch???

Does the trans pour out its oil from where the prop shaft had been
removed at the back, when I remove the motor and trans out together? I
presume.


Any answers, please write. i presume that i have the dave bean
conversion.

It definitely does and I speak from experience. I just forgot to drain the
transmission before I removed it and when I did, my garage floor looked like
the Exxon Valdez had been there. I was cleaning off sea lions for a month!

There's a lip seal in the back opening of the tailshaft housing that seals
on the OD of the driveshaft. When the driveshaft is removed it leaves an
open gap between the seal's ID and the transmission's output shaft.

Hi Steve,

The differential output shafts are held in by the bearings which have a snap
ring holding them in. You should be able to remove the snap ring and just
pull the shafts out. If they don't move after the snap ring is removed they
may have some corrosion holding them and a slide hammer should get them out.
A little heat to the aluminum can help, but usually isn't needed.

After removing the shafts the differential can be removed from the left side
(drivers left) of the chassis, but not the right side. It takes a little
maneuvering but it will come out. This is much easier with the body off than
with the body on.

I don't know about the CV conversion since I don't have one, and probably
won't be able to afford it for a few years.

I found removing the engine, then the transmission the easiest way to get
things out. To remove/install the engine when it is attached to the
transmission you have to rotate the top of the assembly towards the drivers
left of the car part way through the operation so that the oil pan will
clear the front crossmember while the tailshaft rises to the tunnel opening.
This is, in my opinion, more of a pain than removing the bolts holding the
bellhousing to the block and taking them out separately. Also this way the
tranny can be kept level while it is being removed and not as much gear lube
will drain out.
