9-inch rear end question.

Hi all, I'm new to the site and new to restoring old fords! I have a 1978 f-150 Ranger XLT 4X4 w/ C6 auto, NP205 transfer case, 351M, and the ford 9-inch rear end with 3.50 gears. My question is on the rear end. I took the third member out to do a pumpkin gasket, and pinion seal, U-joints, Wheel bearings and seals. When I pulled out the axleshafts the wheel bearing sat about an 1/8 from the end of the axleshaft, or the hub. Is it supposed to sit there or should it be pressed as far on as it can go? Also, when I put my axleshaft back in, do I just push on it until it stops or do you have to tap it in farther with a hammer? I feel like its not going in far enough and there's no way to tell because the retainer plate just tightens up and doesn't push the axleshaft in. Any help would be appreciated. OFF TOPIC: Could someone list every possible thing that I would need to put a 390 w/ c6 auto from a 1976 2-wheel drive half-ton into my 4X4?because that's what I have in mind. Many thanks.

The bearing with the seal is pressed on as far as it will go by its self by pushing on the inter race only, it breaks very easy and then your wheel will have in and out play. After the bearing is pressed on you then press on the retaining ring as far as it will go.

No, you do not use a hammer to put the axle in. When you slide the axle in you move it so the end of the axle goes up a little, push in on it and turn. You should feel it slip into the side gear splines. Then the retainer plate will push the bearing-seal on in. Make sure the hole is clean and round, the resistance you feel should be from the seal only.
