I am still driving on my OEM shocks with no rebuilds after 15 years and am thinking about a rebuild. But I'm not sure if they even need it or if I should just keep going. Is 132,000 miles on these shocks totally normal and can they go way longer than that or am I kidding myself? It seems to drive fine with no bouncing really, but it's a little rough and slightly rattly on occasion but it's so hard to remember if that's normal or if the ride/handling would be totally transformed by having them rebuilt? How far can most people go on the OEM shocks before having to replace or rebuild them? My mileage is mostly around town on pavement that's not too great with one or two cross country trips and a couple of mild off road outings. What are the normal symptoms that something needs to be done about the OEM shocks? I don't see anything leaking or broken so maybe I'm totally fine.
