Just curious if anyone has an idea if there’s a Dorman/aftermarket seal kit that includes the O ring for the lower coolant tank hose that runs over to the thermostat and heater core? Found Dorman 926-189 but not 100% sure if that seems to be the right kit. From my understanding the tank is the same for (almost) all engines in the 12th gen and I’d imagine that the seal would not be engine dependant as well? I know the hose is pricey but I’d rather not replace a whole hose if I don’t need to for one single o-ring

I had a nasty clunk in the rear end of my 2016 F150. Had a look, and the middle leaf in the drivers side leaf spring broke in half and shot out to the inside of the truck. I started tearing it apart today, hoping to take the leaf pack to a spring shop that was recommended by a few buddies that are heavy diesel techs that can actually make a new individual leaf. I looked at the passenger side leaf spring and didn't see any blatant signs of cracking or excess wear. Its a bit crusty but I do oil spray my truck yearly. Shocks are still good. Should I be taking off the passenger side and also bring it in to have the same corresponding leaf replaced? Does the "replace springs in pairs" rule apply here? If I were putting a whole new leaf spring assembly in I'd be absolutely be doing both sides but if i can save several hundred dollars by not replacing entire leaf springs, I, and my wallet, would prefer that route
