There is no fix for worn hangers other than replacement.

The knurl under the head of a greaseable shackle bolt has a particular purpose. The knurl locks into the shackle plate to help prevent the bolt from spinning during spring compressions. Broken welds are a good sign the bolts need replacement.

The knurl is welded onto the shackle plate on the outback trailer springs to stop the bolt from turning. With a rotating bolt in the shackle plate, wear significantly increases.
