I've got a brand new 36 PE, Ive put approx 7 hours on it after it being returned to fox NZ for which they said they couldnt find an issue but its still there, they said they "pulled damper cart, greased IFP, new fluids - all fine"
My LBS is also convinced that there is something in the fork knocking and sounds/feels like the Air side - you can put hand on the air side by the dust wiper and feel it really strongly.
the below video shows the sound but needs volume turned up sorry - i can feel the movement in the fork when climbing anything rough and when unweighting the bike across rough stuff. Trying to see what others think of this??? And yes its the fork, we took the fork out of the bike and can replicate the sound.
