Seals on front differential

Going to tackle replacing the front seals on my 93' 4X4 S-10 Blazer and was wondering if anyone has advice on what tool(s) I may need to remove the old seals and install new ones? I'm mostly asking about a seal installer and remover tool. Just finished replacing the head gaskets on my wife's Astro so now I'm ready for the next repair.

I would seriously invest in a Chilton's AND a Haynes repair manual for that truck to help you.

It will show you exactly what to do along with the tools needed.

Best 30 bucks you will spend in your life.
