Im replacing the Idle arm, center link.
I got a problem I neeed answers to !

1. the tie rod bolt that connects to the center link(on the side near the pitman arm) keeps spinning when I try to put the bolt on?

 

1 try to pull down on the tie rod and have some one start the nut.
2 tap it with a rubber or plastic mallet
3 sand the shoulder with 220 sandpaper to rough it up a little bit and then hit it with the hammer( see #2).

The tie rod end has a taper to it and fits snug in the hole, you just need to get it in far enough to stop turning.
