Help please. Differential side oil seals

[AZPete]

Oil was leaking from both sides of my transaxle differential - where the axle shafts enter at both sides. I bought two side oil seals from the dealer for the front diff. I removed the axle shafts, replaced the oil seals, inserted the axle shafts carefully. But, both sides still leak! I hope someone here can give me some clues or tricks that will help when I do it all again. The old oil seals were bigger diameter than the new ones, but the new seals fit snuggly on the axle shafts and otherwise looked the same as the old ones. The FSM shows Special Tool ST28399SA010, oil seal protector and ST18675AA000, oil seal installer. Do I really need either of these tools?
