Default control arms

Hey guys put on new control arms a few months ago along with bunch of other new front end parts. But anyways the front bolts(horizontal bolts) were pretty nasty and rusted and didnt seem to go back as far as it should, it got tight though. Well when I hit the brakes or go to take off there is a clunking noise. So me and my buddy looked at it and when you turn the wheel far enough you can slightly hear the noise and found out the noise is coming from where the front control arm bolt goes. So what im wondering is did the bolts maybe not get tight enough and the control arm is moving just enough to make noise. And if thats the case could I just buy like new grade 8 or 10 bolts to replace em or are they a very specific diameter that I should get new ones from Chrysler

i would remove the bolt and squirt some penetrating oil up there on the nut using a can with a straw. while that soaks, clean the bolt threads with a wire wheel and lube the threads with a moly lube before reinstalling. i'd also recommend only touching that bolt with a decent impact gun as it's far less likely to break the weld that attaches the nut to the frame.

the moly lube is good stuff. when building an engine using it you generally torque big bolts 15-20ft-lbs less. im not a certified mechanic though, just good with rusty junk.
