my buddy has an 09 assault, been a headache since we picked it up( you may have seen my other threads). We checked the sliders and they are wore right through, only in one spot tho, we removed the front and rear outside wheels but all the inside wheels are in place, sliders are wore right theough to the rails, but only behind where the front idler wheels would be, the rest of the sliders were ok, black onm the bottom but ok. The sled only has about 300 miles on it. Thanks!
