Yes get a strong one because those things can be tight. Be cautious not to scare the outer edge of the housing were the seal seats by praying something between the two because it will leak between the seal and the case if it scares. It often takes some time to get the seal out because of the limited leverage from the tool, if it moves just a little work it out slow. The important thing is to put everything back proper; often that is putting things back just the way they came out, like counting the turns of the nut, you are basically resetting the bearing similar to a front wheel bearing , but with a 100 to 125 pounds of torque on the nut and a very slight drag on the bearing.
I put the new seal in with some kind of gasket shellac around the outside metal and a little grease on lips of the rubber seal
