I used this the first time I was into my T/C.

 

It's not difficult. I replaced the input seal on my '98 Jimmy. Take the transfer case off the back of the transmission. Once it's unbolted it will slide right off. There's a retainer ring that holds the input seal onto the shaft. It unbolts from the inside of the transfer case. Once it's off, drive the old seal out of it with a seal driver. Press the new one in. Reinstall the transfer case. Voilą!
