[QUOTE="RaYzerman19, post: 1247570, member: 18388"] I'd say shocks are not done until they're done.... test it. If it's not leaking, that's a good sign. If it bounces the suspension up and down, and it will no longer have any damping regardless of where you set the damping, it may have lost it's nitrogen, then it's done. You can usually tell during riding if it's not damping any more. It's not always true it's done at 30k, it could last a fair amount longer than that. There's no magic mileage for changing fork oil, many have gone way beyond 30k and they haven't looked all that bad....... it really doesn't lose its hydraulic properties, but aluminum oxide and teflon worn off bushings will leave some sludge in the bottom of the forks. A lot of sludge and it will start to affect damping. It will look very dark gray and may have a foulish odor. To drain it properly, you disassemble the forks, flush, replace bushings, seals and oil. If you want to do a spring upgrade, that's the time also. [/QUOTE]
