Dropped my car off in the morning at the place across from work and went to pick it up in the arvo on the way home. When I arrive there the dude says we couldn't do the alignment cuz your idler arm is 'badly worn' and you have 2 split cv boots

What does a 'badly worn' idler arm mean ? I've climbed under and checked it out, looks ok, no movement in it... how do I fix it

My mate said to paint it and take it back to 'em and say it's a new one
