Next time you pull a wheel off and you notice that the Shock has oil stains that start at the top of the shock (where the coil spring sits) and leaking towards the bottom it means that your shocks are slowly giving up , if you have slight leak (sweating) don't panic its no big deal but eventually at some point when they leak more you will need to change them. Take a look at the picture which clearly show a leaking shock.
Happy motoring.
