A couple problems trying to figure out
 

Hi all any help is appreciated.
I have a 94 extracab 4x4 3.0L v6
1. High idle around 1100-1200rpm cold or hot all the time tried adjusting idle speed screw no change.
2. All of a sudden when I put my high beams on my headlights go out completely. But sometimes they work like normal.
3. When I turn sharp like backing out of a parking spot usually to the right I get a clanking or cracking sound from the front left. I replaced both front axels with new ones when I first got the truck in July because of a safety to register it. When it was on the hoist last month for a new starter I noticed the lower ball joint rubbers were torn, could it be my ball joints?

Again thank for any help.
