Many Mopar lower control arms have a lot of slop between the torsion bar pivot and the body of the control arm. This doesn't seem to cause a major problem, but there's no reason not to fix it. The fix is actually quite simple if you have a grinder/cutoff tool and a welder. Some arms were actually more spot welded so they have to be drilled out. If I come upon another set of those I will update the video or add a new one.
