Front axle I.D.

1994 F-250. 460. 4WD. E4OD.
All stock on the front end. Might be chasing a bad bearing issue. Getting a "growl" that goes away when I stop, or turn left. No drive ability issues, no shake, no shimmy. Looked up bearings, they seem cheap enough to just trigger the parts cannon on, as I am sure they are stock. Does the attached VIN sticker help identify what front axle I have? Or is there a tag on the axle I need to reference?
Thanks.

Should be either a Dana 44 or Dana 50 if still TTB. Is the tag still on the differential? How big is the dial for the hub locks? That will help determine which one it is.

I thought the D50 was a 4600 lb axle?… not that something else couldn’t have been swapped in at some point. It should be embossed on the bottom of the differential if a D50.

Yes the D50 has a 4600 lb axle rating, but I’ve read that Ford derated the axle for “safety” reasons . My axle is a D50 in a 95’ supercab and my axle plate says 3850# rating .

and the rear axle if Sterling 10.25 was rated at 6,250 pounds , but derated to 6,084 because the stock tires were only rated at 3,042 each.

Thanks for all the help everyone. I appreciate it.
However, my local parts guy doesn't show parts for a Dana 50.. But does for a Spicer 50. Is the Spicer 50 the same? May be a dumb question, but, I'm an engine guy, not real knowledgeable on axle stuff yet.

Your parts guy is an idiot. It is a Dana axle. Dana is the parent company.

Well, I wouldn't disagree. Lol. I assumed it was the same as rockauto.com shows Spicer as well.
Any idea how hard they are to replace? Or just a simple pull old one out, put new one in, torque to specs?

Not quite that simple but not hard. Remove brake caliper. Remove locking hub. Remove wheel bearing nut. Slide rotor off the spindle. Be careful since the outer bearing will fall out of the hub. Remove grease seal from the back of the hub. Clean old grease out of the hub. Pack the new bearings with grease. Install new seal. Since you are this far in, I suggest you remove the spindle to inspect and grease the spindle bearing but that is up to you. Install the rotor and torque the nut to spec while turning the rotor to help seat the bearings. Reinstall the locking hub and caliper.
