u/Ok_Today_475

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
