I do a lot of off road riding,and have the same kind of front forks on my wr 426,as the s10.This might save some trouble for someone . These seals can leak. This is what I found helps a lot, keep the the fork slider clean. If I run through a wet or muddy section when I stop for a break, I will clean the slider just under the dust cap and work my way down getting the dirt and dry mud that can get stuck in between the seals and the slider.The dry mud will damage the seals. I keep an old sock as a rag for this, loop it around the slider and go back and forth. If I did any offroading and dont plan on a wash, still get the slider clean before the next ride because that first bump with dry dirt will hit the seals. Even moving it by hand and hitting the front break can make the forks compress enough to hit that dry dirt. Also tying down in a pickup truck can be hard on the forks. They sell a plastic stopper so you can get it tight without damaging the seals. Something I do with my dirt bike that I might not do on the s10 is pack grease on the dust seal and slide it back in place.
