Need help 2004 Dodge Ram 1500 rear wheel bearing replacement

Hello, I have a 2004 Dodge Ram 1500 with a 4.7L V-8 and the rear driver side wheel seal is leaking. I took all the out side stuff off but the axle will not come out. Someone told me it had a C-clip holding it but I don't know what to look for in the Differential. I have the new bearing and seal but not sure what to do next. I did get a dif gasket but did not want to pull the cover and not know what to look for. Anyone have pics or a manual for this type of job???
