Bent USPS Front Control Arm (1 Viewer)

Derek, all trucks are different.

Yep, I agree with this which is why I wrote what I wrote.

I may have been one of the first guinea's for the 4"/Christo arms sans DC shaft. Works like a charm .. I'm hoping most everyone will find it works on their 80, regardless of the subtle truck differences.

And this probably explains what's going on. In my case J springs, Slee's Control arms and the front stock drive shaft produced vibrations. My truck seemed to be more susceptible to vibrations than others which is why I'm running DC shafts on both ends. My vibrations are gone now... or mostly gone. If they are their they are very minute and hard to distinguish from tire/engine noise.
