Well, after crawling under the rig per my previous post I found the right side bracket broken as per pics by others. I have 15,000 mi. on this rig so it's a Ford warranty deal but I ordered the parts from my local Ford guy so I have them on board for the next time. The parts are cheaper than the fuel to go get it fixed for free. I will have Ford fix it, though.
Les, my local Ford parts guy, pointed out that the sway bar for the 24K-26K chassis is stiffer and actually costs $158 compared to $196 for the 16K-22K.
That, along with the CHF might be a good way to go. The Roadmaster bar for $500+ probably works well as it should for that kind of money.
