Became aware of a rattle/clunk from right rear area of truck. Tried to find loose item like trailer hitch or item in cargo area but even with everything taken out noise continued. Finally got under the truck-??s rear area and started pushing/pulling on things. Immediately found completely missing bolt and rubber cush on right-hand sway bar mount clamp. Sway bar was unanchored and moved freely, banging parts on the rear brake and bearing area. I have photos and video. One bolt still present in clamp: removed that bolt (very easily) and discovered NO thread lock or lock washer. This bolt spun out freely by hand. No lock-tite nor lock washers on left-hand side either. Honda parts sold me a rubber cush and I replaced all bolts INCLUDING thread lock this time. On driving, noticed IMMEDIATELY more stability and far less -??head-toss-?? on normal smooth highway. And no more clunk.
