I have found this is not the problem at all. The sway bar is sacrificial and is the weakest link. Happily it is an easy fix. The swaybar endlinks can be removed and replaced in a 1/3 of a day with simple tools. In order:
- buy the links
- jack up vehicle remove tires, have on safety stands
- the endlinks can be easily seen by comparing to purchased ones. They are about 8-10 inches long with 4 plastic mould dots for the bushing on either end, The are connected the the sway bar at the bottom and to a welded bracket on the strut.
- remove the two bolts on one side (use penetrating oil for a bit)
- replace and torque nuts. same for other side
- enjoy your clunk free ride
