Last week a small clunk could be heard on bumps. Right side. Definitely suspension. Three days and no luck finding it. Finally on the last try, the suspension stopped perfectly on ramps. I grabbed the antisway bar link. It moved.
I grab a 6mm, not a 7mm like a YouTube video says, and an 18 mm offset wrench. Sure enough it turned maybe 1/2 turn. All other four connections were tight. Lesson learned, don't trust an inexperienced though good helper. An Impact doesn't work well all the time on links. Annoying that it took 1700+ miles for it start clunking a bit.
