Both of mine broke within 3 weeks of each other at approx 10K miles, where the two pieces join before it bolts to the underside of the car. I took a short piece of heavy duty shelf leg and cut the 90 degree leg into two flat pieces of stock about 5 inches long with holes all along the length. Then welded the ends, the long length and the holes to the existing steel hanger on the bottom. Then re-welded the angled steel brace in place on top. Put a small angled piece of the leg along the top and welded that to the two pieces on either side of the old break.

The extra steel has stiffened up the hanger so it does not flex as much ... which originally caused the breakage.

That was about 5K miles ago, and no problems to date.
