pnp522 thanks for your response. Yes that's exactly the one I'm removing. I did unbolt it from the cross member, which I had to do to remove the front shaft. The problem is that it won't slide off the output shaft. I'm assuming that it shouldn't need any special tools and perhaps the bearing is probably just seized up. I sprayed some PB Blaster on it yesterday, hopefully it will free it up.

Can anyone confirm my assumption?
