I have a SVX and iam doing a 5spd swap, and right now iam trying to get the rear diff off. I was wondering how to get the half saft how the spline of the rear diff? Its a limited slip.

If there isn't a roll-pin like the front, then it should just pop out. (I know this is how the legacy and impreza axles are in the rear, I've just never had an SVX apart back there).

thanks, i will see if it will pop, how much force is required to pop the half shaft out?

not a lot. Just use two flat screwdrivers, one on each side of the axle. 1 Simple light jolt should do it. Don't pull on the axle to get it out.
