I own a 2008 Toyota Tacoma access cab off-rod 4x4. A leaf in the passenger side leaf spring broke while driving. I was driving along and I started to hear a clanking metal on metal noise that I had not heard before. I was close to home so I drove there and when I looked underneath the second leaf from the top was broken in two right behind the u-bolt holding the rear axle to the leaf pack. I had it repaired by a local shop who replaced the broken leaf and added another full leaf to both leaf packs(passenger and driver side) on the truck. Before it broke, the springs on both sides were already flat when unloaded and if I put any amount of weight in the back I was hitting the bump stops very easily.
