Yes a bad idle arm can cause your trucks toe in and tow out to change dramatically when moving, causing your truck to pull right and left. But also a bad castor or camber setting will also do this. I recommend changing your idler arm as soon as possible because if it breaks you will loose control of your steering. That would be bad. Also get an alignment after you change your idler. I hoped this help you.

I have no power to anything in my 1986 pickup, replaced broken ground wire, there is a white wire from the battery cable that appears to have broken off of something. Don't know where it goes.
