axle bearing replacement

Well got the old slide hammer and got the axle out,it took quite a bit of bom bom to dislodge the axle. And can you imagine the bearing is bad 60 years old. My question after taking the old bearing off to replace with new one. Is that shaft tapered I believe it is how far down on the shaft will be the final resting place for the bearing? I looked but cannot tell. Any advise on replacement would be fantistic. It also looks like the brake carrier plate along with the flange on the end of the housing is rusted. It kind of ate into the flange on both parts. I want to replace the carrier plate flange I think that is what they call it. Anyway the piece that the gasket fits against.

I know this bearing is kind of pricey but I think I might go for it and replace it . I don't have a press . But maybe i will chicken out take to the machine shop instead.I am glad I took it apart. This truck sat some 20 years. So now to the other side.

According to the shop manual:

Quote:

When installing a new bearing and retainer, be sure the bearing is seated against the shoulder on the axle shaft and the retainer is firmly pressed against the bearing.

This is for an F-1, F-2 through F-8 are a different set up.

Thanks Bob for the diagram. The grease baffle is the piece that has some heavy rust at the bottom I don't think it will be a big deal after cleaned,put some RTV and gasket and good to go. Thanks George in Texas

Thanks Bill for the part numbers that will be a big help. When I do go for parts on the 51 I always get that look! like What Oh! you mean a F100 no F1. Any Way Thanks Everyone for the help. I did have one more question, I took off the back cover and looked at the gears and they looked fine.There was rear lube in the rear end so it did have some oil.I drove the truck for about 6 to 10m miles before tearing it down,of course not enough to tell if the axle bearings were bad it was all I could do to keep it straight in the road with the bad steering.LOL

I said all that to say out side of tearing the whole rear end down and rebuilding, anyway to see if the inter bearings are bad. Doesn't seem like there is a lot of play, but one fella told me if pinion seal is leaking it is a good chance that it needs to be rebuilt.I am going to replace both sides of the axle bearing and race and go from there . Again thanks for all the help.

The Dana 41/44 is a pretty rugged diff, but people used to use and abuse these trucks too. A pinion leak after 60 years is hardly a guarantee of worn pinion bearings.

A trick an old timer showed me to check pinion bearings was this:

Disconnect the driveshaft from the diff (only), with the wheels securely chocked. Put the parking brake on tight or have someone step on the brake hard. Put a socket with breaker bar on the pinion nut (or if you don't have one that size, you can use Channelock pliers, or a long bar, on the yoke). Gently build up torque on the pinion until all the slack has been taken up, then give it a good pull. If the pinion bearings are worn, you'll feel the pinion shift off-center.

Thanks for the tip. I will have to try it once the rear end is back in the truck.LOL Looking back when I got this truck I should have fixed a few things and drove it to enjoy.But no I got the big idea lets pull the flathead and rebuild it,that was the beginning of the end . Now down to the frame and going back together.

It has been a long time since doing a big project like this,and when you get a little age it sure takes longer.lol But one thing I am really enjoying the heck out of this truck and I want to get it back together.
