Corrosion on Rear FOX shocks AARRGH....

[florchak]

Talked to Fox, they do not do them in house and had not heard about it but figured it was bad clear coat. They thought Ford would take care of it. Will stop by the dealer today even though it sounds like from this forum that Ford will not cover it.

Well guys I went and talk to the service manager from my local ford dealer and he told me that ford has denied the warranty claim.. He told me that there must be a hole in the shock body and the shock would have to leak for it to be covered... .

nothing a little Gallium therapy cant do , LoL!!!!!!

My rears are more corroded then these pics! They are bad!! I bought mine used in MI and I live in Chicago. A 2010 w 37K. I would love to see a dealer warranty these but don't think it's gonna happen. Figure at 50k or so I will just buy some newer take offs

shock corrosion

The salt up here apparently just kills the finish on the alluminum fox shocks. Is this common for everyone else? Is there anything to help with this?

There are some posts already.

Same problem here at 20k.
No surprise that neither will warranty because of volume and cost.
Any suggestions on maybe cleaning/removing?
I wash the truck every week in the winter and make sure the shocks are sprayed down and still

Right, found it. Need to delete.

Correct me if I'm wrong, but I do not think these shocks have a clear coat. It is more likely that they are clear anodized.

If any of you have looked at your rear diff cover or axles and seen rust forming, you can see what kind of sand blasting the underside gets (even just on the streets).

If the shocks were painted, the same thing would be happening to them. The pattern of the shocks suggests to me it's something else. Anodization has a much higher tolerance for wear than paint, but it is still susceptible to cracking from thermal stress.

These shocks get pretty dang warm when they are working, so this is my guess. Heat developed, cracked the anodized finish and nature took care of the rest.

Chrome plating (trivalent, which is probably what they would use. Not hexavalent) would not be much better than anodizing. Hexavalent plating would be awesome, but is expensive because it is highly regulated and toxic to produce.

Basically... nothing can stop this. But, preventative maintenance should help, such as AMSOIL. Here's an article about removing surface oxidation from aluminum: How to Restore Oxidized Aluminum Finish | eHow.com

Ok so I thought I would try and clean one of my shocks with the above link from firematt. This is the before picture.......

This is after but not fully cleaned. The bottom of the shock right above the plastic shock guard I used a rag with lemon juice and salt which did not do much at all. The top of the shock you can see is a lot cleaner I used a Scotch pad and lemon juice.
