Pull out the driveshell and axle first, then get a good quality long thin punch and drift out the bearing on the drive side tapping at 12 o'clock, 6, 3 and 9 until it comes out. Then you'll be able to get to the spring. Don't stretch it too much or it'll mis-shape. Put the spring and ring back in and tap the bearing back home square with an apropriate sized socket. Re-assemble the rest of the hub. Done.
