Not that I know of. You will need a decent sized press to get them out/in. The inner bearing is a Timken JRM4549ES not sure of the outer. (I have a toasted hub assy sitting next to my desk that I replaced)
I got a new hub assy from an ebay seller for $70 shipped. I was kind of skeptical for it quality wise, but it came with a lifetime warranty, so we'll see how long it lasts. I plan on swapping to a solid axle in the next year or so, so I just wanted to get the explorer up and running as cheap as possible.
