some back story
I realize part of the trouble with this thread is that I have stuff I've done over the years on the K5 (the General) but that information isn't here. So when you all read this you don't really know what I've already got going on. So in light of the steering discussion I'll go over the set up I had on the General.
I did the typical crossover steering setup when I swapped in the Dana 60. Followed that up with hyrdo-assist from PSC; cylinder, hoses w/re-usable ends, and standard pump. I managed to bend the HD tie-rod and dinged up the hydraulic cylinder a little.
It wasn't anything that made the cylinder unusable but I decided I should go high-steer so that I didn't eventually wind up replacing a damaged cylinder.
I purchased an ORD driver side arm to use for the high-steer, but I quickly realized this wouldn't work once I tried to install the tie-rod and drag-link on the passenger arm. The problem was that I had 52" springs with the axle moved 2" forward. This caused the tie-rod and drag-link to bind up.
I found a WFO Concepts steering arm on the forums that was lightly used. It is the style on the left below.
At the time I was getting the steering arms their driver side arm diidn't have the 5th hole for Reid knuckles and I really wanted that feature. I wound up ordering a new arm identical to the used one I found.
Using these arms put the tie-rod behind the axle. This solved the problem created with the axle moved forward 2".
In the process of setting up the steering arms I learned something new about our old drill press. The used steering arm I picked up had a tapered hole for a tie-rod end but I already had heims for this purpose. I had to drill out the tapered hole for a 3/4" bolt. I was trying to figure how I could drill a straight hole through the end of the arm that was angled. It was then I realized I could rotate the platform on the drill press. It even has degree marks. I put an angle finder on the arm found the angle was 8 degrees so I rotated the platform to match. Clamped the arm down and I was good to go.
I hinted at Reid knuckles above. I decided with high-steer that was boosted with a hydraulic cylinder I should upgrade the knuckles. I picked up some Reid knuckles from Offroad Design. It's obvious from the pictures whey they are a good upgrade:
I also replace the spindle studs while I was at it. Parts Mike was the only place I could find at the time that included nuts with the studs.
The WFO steering arms I'm using are the springless type, meaning they eliminate the spring that normally pre-loads the king pin. Instead it uses large set screw threaded into the arms that is torqued against a washer on top of the king pin bushing in order to provide the pre-load.
Here you can see the recess where the washer sets. You can also see the large threaded hole in the middle for the set screw and the grease zirc passage.
You use an allen wrench on the set screw to adjust pre-load. There is a jam nut to lock it in place.
I used a fish scale to pull on the knucle at the tie rod hole. None of the linkage is attached.
The fish scale should read 25lbs at the tie rod hole. The trick is to give the knuckle a good steady pull following the arc it moves in naturally. I wish I would have used deflecting beam torque wrench on the set screw so I would have a torque setting to use for easy checking from time to time. I think somewhere at one point I found a torque setting someone else came up with but I don't remember what it was.
As a side note, when I first installed my Dana 60, 1 knuckle had 2 of the lower cap bolts stripped out. I drilled out and tapped the 2 holes for the next size larger bolt. I picked up a new lower cap from Parts Mike since I could now use the correct sign bolts on the Reid knuckles. Little trick I learned is to weld a ring around the zirc fitting to protect it from getting knocked off on the rocks.
I tried to be a little more creative with the new cap.
I also installed the Stage 8 spindle nut setup for ease of maintenance in the future.
Here's what the finished install looked like.
You can see in the picture above I had to use a tall misalignment spacer. This was to clear the springs when they are arched in droop and the wheels are turned. They just barely clear now. Which is the problem I have with using this setup on the crew cab. I'm going to be using shorter springs (48" vs 52") and I think the new springs will have more arch to begin with. So I'm going to have more trouble with the tie-rod hitting the springs.
I think the biggest mistake with this setup was putting yellow arms on the orange knuckles.
