I don't rock crawl, no suspension mods, but I do carry full load on forest service roads and backcountry jeep trails. One mechanic recently told me I'd be needing new shocks soon, another one says they're fine. I do seem to notice a little bit more sway after 5+ years but it might be the power of suggestion. I'm at 7500 miles, maybe half of it off pavement. When would anyone recommend shock replacement and what shocks would be right for what I do?
