Fox’s Float series of rear shocks are the most popular shock on bikes these days. They are very reliable, but one thing that commonly gets overlooked is replacing the DU bushings. Over time the PTFE coating (orange) wears out, this is when you will start to hear creaks. Your fancy aluminum reducers will also start to wear since it is just metal on metal now. Bring your bike by the shop any we can use a special installation/removal tool to replace them.
