I have Rough Country adjustable control arms. The lift is around 5" w/o drop brackets. If you grease the crap out of them the are quiet for a day or two. The is a fair amount of slack in the threads. I am going to get some drop brackets soon. My question is, has anyone tried to make a bushing to fit between the end of the larger tube and smaller one. I was thinking about using some type of rubber hose with the same ID as the axle end of the arm. Then i would slide it up between the space and in the end creating a bushing and eliminate the clunking. I would think this would help with keeping the grit and water out of them as well. Any opinions on this would be nice.
