Help - Inner CV Joint removal???

[Jay-ZS+]

How the hell are you meant to remove the inner CV joint, The part that is full with grease, connected to the gear box.

Just in the middle of replacing the diff seal and can not get the inner joint out, haynes says to prise out but have been swearing at it and nothing is budging.

Also anyone ever managed to drop the sump without removing the exhaust manifold, Looks like it would be very tight.
