Mojave shock end cap screws rusted

[Jaxmax]

The way it rusted, it was not 304 or 316?stainless, more like plane carbon steel. A dab of paint will solve it but I think if it ever has to be unscrewed or adjusted it would strip right away. I can see Fox replacing whole shock as having the dealer breakdown the setup between Res. and shock and unscrew the rusted part not go well……Jack

They are all gonna be like that...

I suggest cleaning it off with some scotchbrite and painting it if it keeps you up at night

It doesn't keep me up at night. I just know from projects I've worked on that Stellantis has complained about smaller issues. If Fox can't select the proper material to prevent rust then do I really want Fox shocks?

Its more of the principle of it that it should be designed properly with the proper spec'ed material.

I'm taking it in for another issue anyway so might as well get them to look at it. Maybe nobody has complained about it yet so engineers at Stellantis haven't figured out about the issue yet.

The blue passivate I use is good to 240 hours. It's not the zinc plating it's self, it's the next step - the passivate that secures the ability to pass the salt spray tests which is measured in hours to red rust.

Some info on the testing -
Salt spray testing is a laboratory simulation of a corrosive saline environment. It is used as an accelerated means of testing the ability of surface coatings to withstand atmospheric corrosion. Also known as salt fog testing.
Salt spray testing is used as a stand-alone corrosion resistance test and also as a component of ISO 12944-9 (previously known as ISO 20340). For both tests, the salt spray process is handled the same way, conducted per ASTM B-117.

It is very likely whoever spec'ed the screw did not specify to re-passivate it. And being that it is in an obscure place, and the mojave just came out, it is possible nobody has seen it yet. And nobody has complained about it yet no warranty claims.

My OCD self would be going nuts over that - I'd likely have pulled that screw and totally refinished it by now. I have pulled screws and bolts out of my other vehicles and refinished them LOL.

Mine rusted a tiny bit but I also use Fluid Film every winter and summer too. Doesnt look terrible on my rig, just slight.

All 4 of mine are rusted as well, just like the picture above. I noticed the fronts the other day, and brushed on some heavy wax type corrosion inhibitor. Haven't done the rears yet.

I'm not a shock expert by any means, but that should be the area where they pressurize the reservoir with nitrogen, right? So, I'm assuming that the screw we are seeing is just a cap that can be replaced and removing it will not release nitrogen.

I'm curious to hear what the dealer says about this. I can't imagine that they are going to want to replace a complete shock because of a rusty screw.

@KB34 Standards....what standards. Those don't exist anymore. That is a four letter word.
It's not nice to reject a part because it is insufficient or lacks quality. We have to all accept even those lesser parts that don't measure up.
Maybe that screw identifies as as something from the salt belt. Who are we to judge?
?

Yeah I'd be annoyed if I saw that too nothing that some sandpaper and rust reformer can't do,

I got a Jtrd and there's already some spots were there's rust and the thing only has 2k miles and I live in Texas,but I'm not gonna take it into the dealer and be like hey replace my truck cause there's rust spots on the axle tube and chassis cause it didn't pass a certain standard, they're gonna look at me dumb if I just talk about a certain standard,the dealer is gonna tell me to e'f off basically

It's already happened on my dad's 3rd gen taco and my sisters jeep jk,and they wont do nothing about it and say it's "nOrMaL" and of course I'm not gonna let that happen and after lots of"NiCe wOrDs" they still did nothing,only did that to satisfy my dad and sister

So moral of the story,just man up? get you some sand paper or scotch Brite primer (I prefer to use it) and some paint and bam small rust problem solved unless if it's a Toyota ?

Also it should be Fox's responsibility to replace the whole shock assemblies and maybe come out with some recall for the screws,cause the head of the bolt will rust and you can fix just the screw head but what about the threads ?

A recall implies there is a safety issue that must be resolved. A surface rusted screw like this isn't a safety issue. It's a purely cosmetic issue. I've seen way worse on brand new vehicles.

Ahhh I never would of known recalls are for safety issues ? I always thought they were for defective/bad quality products and stuff,
The more you know ?

We have had to issue recalls for far less than this before.
This is a quality issue, I agree it isn’t a safety issue, but as someone else said, rust migrates once it begins. It’s like cancer, it’ll migrate into the threads and could cause issues down the road. Yea it could be fixed so it doesn’t look bad, but that’s not the point, I shouldn’t have to repaint screws on a 1 month old $70k truck.

When you pay $70k for a brand new truck and get a “premium” suspension, you expect better.

they are not only for safety issues, just more commonly for safety issues as they affect a greater population size. They are for issues with a high enough percentage of complaints. Sometimes a full issue isn’t issued but they will make a running change and change everything past a certain production date. Then all service parts beyond that will be given the new parts.

People interchange them but don't know the exact definition of either one..... OK.... End rant by the Mechanical Engineer....

Seems some folks mix up engine and motor as well along with spelling errors, mostly with synonyms.
