I have a '97 Ram 1500 Sport. After about the 1st 12 years or so the rear leaf pack on the driver's side started to sag. No jokes needed, because I'm actually a little guy and the rear hardly ever has anything loaded in it. And it has never been overloaded. So I replaced the rear leafs with a set from a used-junkyard take-offs. You'd think the randomness would help, but the driver's side rear leaf is already sagging again. The left side wheel-well is about 3" lower than the right (passenger) side. Were these chronically weak leaf packs? Is there another issue that could be causing it such as a bent frame? Why always on the driver's side, is it because of the fuel tank? I'm looking at getting a 2nd set, but perhaps use Ram 2500 springs this time. Then again, it is almost 20 years old.... FYI - truck used to be a daily driver, but now (last 6-7 years or so) is just a Home Depot weekender and used to tow the boat for launching.
