Fox Float RC losing air...

1292 Views 8 Replies 4 Participants Last post by  Homebrew
I'm curious if I just need to replace the seals in my RC or if I actually have to send it back to Fox? The shock is NOT in the stuck down phase. It just simple loses air after a few minutes of riding. No matter if I only put 50 #s of pressure or 200 #'s of pressure. I've replaced the seals once myself and I've sent it back to Fox once. This is on a bike that was not ridden for about 2 years but I recently converted it to a SS and I've been riding mostly it for the last 2 months. Could the not riding it and then riding it almost exclusively (3 X's a week) cause a problem?

Thanks for the info!

Air leaks can be fixed at home. Pump it up to 250psi and dunk it under water to check for bubbles. Be sure to check the schrader valve. It can leak from the valve itself or around the outside. If it only leaks out riding, the new seals should take care of it.
What is your budget?

Check it to see where it is leaking. If it is the seals, you can do it yourself. If it is the core, replace it.

If you have the $, and plan on keeping it set up as a SS, have it PUSHED for your weight, suspension type, and the fact that you are using it as a SS.

I have found that the Fox shock I have needs to have the air chamber serviced once a year to prevent it from leaking. It sounds like you know how to open the air chamber already. I have not replaced the seals, just clean and grease. After doing that it does not loose any air for about a year. It's such easy maintenance I should do it a couple times a year!

Thanks for all the advice fellas. Holding it under water reveals that the valve is leaking air. So hopefully I just need to replace that and I'll be good to go. Is that something I can pick up anywhere or specifically from Fox?
It is a standard valve core.

However, there are a couple of lengths. Take the shock with you to the shop. The shop will have valve cores and the core removal tool. You are looking for valve cores and a removal tool for a schrader tube.

Good Luck.

Or you can go to the auto parts store and pick the valve core tool for $2. It probably doesn't need replacing, just remove, clean, and reinstall.
Hey Homebrew...So I removed the valve stem, cleaned it and put it back on. I then pumped it up and put it back under water and it's still leaking. It appears is somewhere around the rebound control knob. There's no way to get at it that I can see. Have you ever seen this problem?

I e-mailed Fox almost a week ago and still no reply. :(

That doesn't sound good. There is not way to access anything around the rebound knob. You might try PUSH Industries for a bit quicker turn around (although they may be on vacation too).
