Fox rear shock 'Topping out'

My rear shock (fox vanilla rc) is 'topping out.' After I compress and let off, the shock expands (thank god), and then tops out. I can feel the shock expanding, then all of a sudden stopping and hitting something. There is also a minor noise, a quiet 'clunk.' Any advice besides sending it in, or getting a new one? Thanks.

Your rebound may be too fast or you may need more nitrogen (not sure about that though)

How fast is your rebound set? (red dial)

I was chattin with Crash and he said to take it to a motorcross shop and ask them to fill up the nitro. Sounds crazy to me but who knows? I was wondering what others thought of the idea. (While we're at it, does anyone know how much this would cost?)

my risse trixxy's were doing that for a little, all i did was turn down the rebound (slow down) a few notches. that seemed to take care of it.

your shock needs to be bled. you have an air bubble in it. send it to fox
