When we removed the wheel to change the brake pads, we noticed the stub axle for 4WD is rattling in there, the bearing and seal are gone. Picture attached with arrow to indicate bearing.
Can anyone help identify the parts required? I am having difficulty finding a diagram that shows the parts clearly.
Any advice on stripping this down? Should I do both sides while I am at it? The left side looks Ok.

Thanks for any help on this.




2004 Ford F-550 front axle bearing and seal failed

 

From the pic the axle tube looks dry, if so the seal is good. You will have a little play in the axle. Other than the snap ring at the hub it pretty much just sits in there only supported by the side gears in the diff and out at the wheel hub. The axle seal isnt at the end if the tube but in at the differential.

 

It's more than a little play, it's rattling around in there, The left hand shaft is fine, but the right is very loose. I ordered the outer bearing and seal, will see if that solves it. If anyone has a parts drawing for this component it would help a lot.

 

there is no bearing in the axle where your arrow is pointing, just a dust seal. The right side will be looser than the left because it is a longer shaft.

 

That explains why I couldn't identify the bearing on the drawings I found. Great help, thank you. I'll change the seal as I bought it.

 

You also may want to check the needle bearing in the unit bearing, it may be worn out allowing too much play in the stub shaft.
