Front Seals loose

[Mercmarquis]

Took a peak under my truck today and found this. Its an 09 F-350 4x4. I dont believe this to be normal. I'm no 4x4 expert, but they just seem to be a dust seal of some sort. Diff fluid seems to be normal level and I have noticed no leaks.

What are these seals called? Any idea how this happened? Would my warranty cover this?

Thanks for the help!

Both mine are like that too. I think its a common problem.

My is the same way. It has been a common problem.
Ford has an updated seal P/N AC3Z 1S175 A
The updated seal cost about $20.

If you are under warranty then you can take it in and get them changed for free. Otherwise it won't hurt anything if you don't change them out right away. You will also need the vacuum seal which is a fairly pricey seal plus a special driver to install the vacuum seal.

Exact same thing on mine.

Took it in last week to the dealer, they replaced seals under warranty.

There was a posting sometime back...about these seals....If under warranty....they will be replace. I had this happen...outside of the warranty peroid. I cleaned the area and the seal with brake cleaner....use a clear ...Loctite adhesive.......applied it to the area on the axel....used tape to hold it in place for a few day....removed tape...problem solved.....traded the truck with 135K miles

Had a grinding noise today followed by a thud. After the thud, the grinding was gone. Did the same thing about 1/2 hour later. Climbed under and noticed my dust seals are the same as those above. Could that be causing the grinding?

Mine is the same way on the driver side. I noticed an above post saying that the vacuum seal would need to be replaced as well and was wondering if this seal could be affecting my auto lock hubs they do not engage?

[WildStyle]

No the dust seal will not effect the vacuum operating auto lock hubs. The reason the vacuum seal in the hub needs to be changed is that it is damaged when you remove it to get the axle out to replace the dust seal.
