Randy's Ring & Pinion Carrier bearing puller. Expensive ass tool but it works well.
You can use a clamshell type puller with a shop press.
If you have a good 3 jaw puller (such as a posi lock) that has slim hooks, it sometimes works. You could probably take a cheapo puller and grind the hooks down also.
Before you pull them, hit them with a penetrating fluid, makes life a little easier.
