2002 Chevy Silverado drivers side front differential axle b

Im changing the bearing in the front differetial where the axle comes out of it
im now down to the bearing and ready to take it out
but ive having problems with it
im a good mechanic and usally dont get stuck on stuff like this
but there is a lil keeper or shim or something in front of the bearing that is keeping it from coming out and I cannot figure out how o get it out of the way so I can get the bearing out
let me explain a lil better
if you are looking at the bearing it has lil notches or like teeth on the out side face of it and the keeper or shim lays in bettween 2 of those teethe on the bearing to keep it from spinning or move at all
i hope ya can help me because its even got the techs at my local gm shop confused
