Cool Grrr...Axle shaft problem needs fixin'

Well im finally going to attack my front axle shaft problem. I would like to know what you guys think. When i remove the drivers side locking hub(both inner an outer parts), and I look at the end of the axle shaft, its not centered in the hub. in fact i have to take a prybar and pry on the outer u joint to get the locking hub innerds out. im thinking that its the bearings but what are the odds that its a bent shaft. i turned one hub into dust already and need to get it fixed for plowing. has anyone dealt with this before?

I would pull it all apart....start with checking the steering knuckle for damage, then replace bearings, seals etc....... sound like they are all toast anyway....... Ensure there is no damage to the shaft where bearings and seals run. If your into it that deep doing all the universals now would be a prudent thought.

Don't these have the needle bearings inside the hubs, sounds like they are toast, also your outer ujoint may be dry and binding they are often bad even when there is no slack.

Needle bearing inside the spindle tubes and the lockout keeps the outer stub axle centered.

Prying out on the U joint to get the snap ring on or off is not uncommon.

i was planning on replacing the inner and outer wheel bearings as well as the needle bearings and seals. like you said though i should just throw in some u joints they all look good but wouldnt hurt. there is a lot of pressure on the end of the shaft and that is why im chewing up the hubs

When you are that close, a couple more U joints now versus taking everything back apart in 3 months to replace it later.

Where is the U joint rack please Ma'am?

Yeah that makes some sense. So would blown out bearings cause that stub shaft to point in a downward position like that? when i took the original locking hub out...it came out in pieces and dust. the splines on the shaft look good but there was so much pressure on the hub it couldnt handle it

Actually it might be that the lockout failed first.
Or at some time a wheel bearing failed and started the hub damage.
Or at some time a U joint got stiff and started the hub damage.

When I had hub problems, I always went with the cheap ones when I replaced them.
I tried hard to get them to break before the axle shaft did, but that was not how it usually worked.

Is this truck new to you?

Just got to thinking, here is a breakdown and the service info at Dana.

http://www2.dana.com/pdf/5324.pdf

When the hub is not installed you only have one bearing supporting the axle.
The spindle bearing is the only support outside the punkin.
So the problem may not be as bad as you are thinking.
With only one support, you should be able to move the end around inside the spindle.

You should be able to move the stub shaft around pretty easy, a dry ujoint will keep it in a bind.

The truck isnt new to me but i never really dove into the front end. just installing 1 ton springs in the front. i can not move the shaft inside the spindle. AT ALL its tight. so your saying that wheel bearings could be the culprit. is there any way to test any of these things?

The needle bearings inside the spindle, but if the ujoint is dry and froze up you wont be able to move it either and it would probably take out the needle bearings too.

Unbolt the spindle to check needle bearings anyway. Then check u-joint movement. I'm betting there tighter than a frogs...... well you know, bound up probably with rust.

Rusty U joints will take out the hubs.
If you can not move the stub axle around easily, I am also going to say your trouble started in the U joints.
