Was hearing a knocking from the front end the last few days. But only on a few bumps on my daily drive then today I heard it a bunch of times???? Crawled under the truck when I got home and low and behold the upper control arm on my rockrunner arms were only finger tight. It was just checked 4500 miles ago and have only had them on their for about 10,000. Just a word to the wise just check them out!!!!!!

 

I had the same thing happen(not rockrunners), but had one of the upper control arm bolts loosen up, im glad I caught it before something happened.
I guess its a good thing the downpipe blocks that bolt from coming out!(and luckily it never got that loose)
