Hey guys, I have a problem. It looks like the driver's side axle shaft bearing and seal have gone out in the front differential on my 2000 Sierra 1500. I've pulled the differential out of the truck so that I can have easy access to the thing and my problem is the axle itself not coming out of the differential. The instructions I have read tell me to take a hammer and a brass drift and hammer it out until the C clamp inside lets go of the axle. Well, easier said than done but I've all but given up on getting that thing to let loose. Anybody have any advice to how to get that axle shaft out so that I can pull the bearing and seal?

Thanks!
