My sway bar bracket bolts broke twice. I thought it might have been added stress after I did the cheap handling fix, but have been told that this is not the case. The second time they broke I went to the local Ford dealer and he did not have the bolts, so he told me to go to the local John Deere dealer and get hardened bolts, which I did. Not long after that I had to take my RV to a Ford truck dealer for a recall and asked them to replace the bolts with original Ford bolts. The mechanic looked at it and suggested I leave the hardened bolts as they are better than the Ford bolts. Apparently this is a common problem, my unit is a 2012, I hope they have fixed the problem since then.
