Fox Suspension Help, Maintenance and Life

Hello,

Backstory: I have a 2015 CM 4x4. I've ran a 4" spacer lift for about 5 years but 10 months ago I switched to 2.5" Fox with Reservoir non adjustable. Daily driven, maybe about 10k per year and mostly city driving. The truck doesn't see a whole lot of off road so not a lot of rough driving except for construction areas.

Whats wrong: I am having leakage on all 4 of my reservoir(pic below). I am hearing weird squeaks, almost like compression noises and only when there is suspension travel. Control arms and ball joints are lubed up properly. I will once again lube up control arms and ball joints this weekend. Noises almost sound like this video from a gladiator: https://www.youtube.com/watch?v=Un7kulLiaoQ

Question: Is there any normal maintenance with these shocks? Am I supposed to have them frequently serviced or refilled if thats a thing? Is this all normal? Are the piston rods from the shocks need to be lubed normally?

Any help is greatly appreciated.

 

The shock in the video definitively is low on nitrogen, should push all the way out and be difficult to push in. Not sure why, some shocks arrive without nitrogen, been told that shipping via air can cause it but idk.. Could check the pressure on the reservoir schrader valve with high pressure tire gauge if you don’t have access to a nitrogen set-up, won’t hurt anything if they are leaking anyways.

 

The video isn't mine, just a video that sounds similar to what I got. If it's low on nitrogen, can it be topped off? I was reading that some people can get easily 50k miles without touching them, but I'm only at 10-11k.

I'll be jacking up the truck tomorrow. Anyone have anything else I should check or look for?

 

Just wanted to update. I checked the Nitrogen. Both fronts have 200psi and the rears have about 120psi. The rear could use 80psi each.

I also found the source of the noise that I have been hearing. It was the piston rod and bushing at the bottom of the shock was making the noise. As a test, I used grease to see if that was the source and the sound went away.

As for the leaking reservoirs, is that normal? Am I going to have to rebuild them soon? City driving, nothing harsh expect for poor roads, but less than 10k, leaking fox suspension.

 

Shocks should all be charged to 200psi.
Did you clean off the reservoirs when you noticed the oil? If not, I would do that and see if the oil comes back. Less than 10k miles, it could be residual oil from assembly. I would recommend cleaning em up, charging to 200psi and check back after a week or 2. If there is more leaking, or nitrogen is low, I would have them serviced.

 

I will try this. See how long it takes for the oil to come back, thanks
