I picked up a Heim joint (Stonecrusher?) steering system from James Duff that I tried to install today. I had to drill the knuckles and pitman to 3/4" for this. I was nervous about that since it's so permanent but with 2 new drill bits it was easy to do and I didn't even have to take the wheels or pitman off the truck. Then I went to install. I need 2 left drive thread heims and 2 right drive thread ones. Of course I got 3 rights and 1 left! I have no doubt Duff will make it right as they're awesome guys, but you can imagine the frustration when I'm plugging along and almost there! I should have mocked everything up first because now that I've drilled I can't even put the old steering back on so she's dead in the water...again.
I'm trying to decide if I should go knuckle over or under. One of the best things about these kits is they can go either way. The problem is it looks like the drag link saddle runs into the crown of the track bar at hard right turn when installed over. It looks like it may a bit when it's installed under as well, but not as bad...and they provided a new crown nut to correct this.
The other concern which may be nothing is I've always tried to get the drag link and track bar perfectly parallel but with this (especially knuckle over) the drag link is past parallel in what I'm hoping is a good way. Is this OK?
Mocked over:
Mocked under:
You can see how it hits the C-bushing thing on full right turn when mocked under:
When over it hits the track bar bolt.
What do you guys think? Over or under? Should I pick up a new normal pitman arm? With a normal one the bars would be more parallel. I'm hoping it's OK this way. I know it's not when the drag link is at a greater angle.
I'm also hoping to get rid of the steering stabilizer with this new system. It is heavy duty and awesome. Just my luck to get the wrong parts!
