Ok, I have a 2004 silverado 1500 4x4. I have two leaking axle seals on the front axle. Pulled the R extension housing and axle, replace the seal and bearing (inner and outer). The problem is that we were unable to get the left axle shaft out of the differential. I have read that you can Pry it out or use a hammer and punch to get it out as well. Tried both and a slide hammer as well, yet there was no movement at all. Is there a clip or something holdingthis in? It just did not want to budge. I would appreciate any help. Thanks!
