I have a 2003 Silverado Z71. While removing the rear output shaft seal on the transfer case, this bushing came out as well. Is this something that can be reinserted from the opening, or am I going to have to drop the transfer case and reinsert from the inside? It also has some minor scratches on the inside of it, so should I replace it? I'm guessing yes to that, but have no idea of the part number. The Haynes manual is of no help here. I'm attaching a picture of the old (torn up) seal and the bushing that came out with it.
