5 or 6 days of riding after coming back from service my RC4 seems to have developed a clunk when rebounding. It happens before full extension, so not fully topped out. It almost seems to happen as soon as the shock starts to rebound. The "noise" can be felt through the frame and makes a lot of noise when riding. So much so that I cut my last day short out of concern for the noise my bike was making until I'd tracked the issue down. Nothing is immediately wrong with the shock, anyone else heard of similar?
