Mojave shock end cap screws rusted

[KB34]

While swapping out my plastic bumper on my Mojave I noticed the end cap screws on the fox remote reservoirs were completely rusted. My Gladiator only has 850 miles on it. These definitely did not pass the FCA/Stellantis salt spray test requirements. I will be taking it to the dealer this weekend and getting them to order new shocks and replace these.

I haven't checked the rears yet, but will do it this afternoon.

Mojave Owners, I would suggest you check yours out as well. If they aren't rusted yet, they might soon be, so keep an eye on it.

Pictures would help alot,if it's a couple of bolts or "screws" that would be very unnecessary,but dealers replace a whole axle for either a seal or a sensor for a Rubicon Locker

It is the one that is in the center of the black end-cap on the reservoir itself, you can't really see it without taking the skid plate off. Yes, pictures would be better, but I was an idiot and didn't take the picture lol. This picture gives the best idea of where I am referring to without having to go remove the skid plate again.

But if you want to get real technical they are "sCrEwS".

A bolt is a fastener that uses a washer and nut to hold objects together. A screw is a fastener that mates with an existing thread or creates its own thread in a material as it turns. This most likely doesn't have a nut on the back side. Same as the SCREWS that hold on a diff cover. People interchange them but don't know the exact definition of either one..... OK.... End rant by the Mechanical Engineer....

Also, let me just say that I work for a supplier to Stellantis as a mechanical engineer. I refuse to accept anything but a replacement on a part that clearly did not pass the strict environmental validation requirements. Yes, it may be just a screw on the end cap of the shock, it may cause absolutely no function issue over the life of the vehicle, but it is a failure of the shock based off the Stellantis validation standards. There is no way a properly spec'ed material for this screw would rust after only 800 miles of driving in GA.

I wonder if that bracket was either made by fox or jeep themselves,and I wonder if jeep/Mopar/fca is the one that supplies the bolts,I know fox makes great stuff so it wouldn't be there fault?
And thanks for the info of the difference of Bolts and "ScReWs"

It isn't the bracket. I'll have to crawl under and see if I can get a picture when I get home. It is the shock reservoir itself, which would fall on Fox as the responsible party here. It is not the bracket, but the cap at the back of the reservoir which they most likely use to charge the shocks with fluid. There is a small countersunk hex screw in the center of the end cap that is completely rusted. You can't see it in the picture but it is the opposite side of where the hose goes into the reservoir.

Lol, what do you do when they won’t replace it where you refuse to accept anything but a replacement ?

Provide them the printed out specification for salt spray testing on exterior components and the pass fail criteria lol.

Which specifically says rust is a failure.

Mine is rusted also, it is a part of the Fox shock, small set screw should really be stainless. I drive in the North East in the road salt and also drive on beaches surf-fishing. It rusted right away. I am not sure if it is an adjustment screw, bleeder or fill port…..Jack

Can you share the documentation, Please and Thank you

Yes, but there are different grades of stainless, some are more corrosion resistant than others.
It seems Fox spec'ed the wrong grade of stainless.

Send the cap screws to me - I'll plate 'em for you. Clear/blue, yellow or black zinc.

I cannot share it here. Might be able to find it online somewhere. I wouldn't have an issue providing it to a dealer but can't post it to a forum.

Be curious to hear how that goes, from what I have read most car companies are fine with surface rust.

I'll let you know on Saturday after my appointment with the dealer.
Surface rust is one thing, but this is enough rust that the proper sized hex key probably won't fit.
