Default 2004 STI steering column & steering rack into 1999 2.5RS

Hey i've gotten pretty far with my 2004 STI swap, but all i have to work with is STI steering column & rack assembly with column link. Steering feels like it binds. I believe the column link ( "coupler" ) is too long. Does anyone know if they make a column link for this setup??? Or what is everyone doing ?
( i also have swapped over 6SP trans. axles, hub assemblies )
Any help is greatly appreciated.

Yes, the link is too long. You can either get an STi column which is slightly shorter, or you can get a modified steering knuckle by cutting out some of the length in the middle and re-welding it.

My setup has an 04 STI Steering column, rack, link, and dash swapped. The dash swap could cause some differences, so keep that in mind.

Mine felt like it was binding too after I first finished the swap. The steering wheel would turn lock to lock no problem, it just didn't feel like it was turning smoothly.

After trying the steering column adjusted as high and as low as it would go I came to the conclusion that the problem was the angle of the steering column to the steering rack. It was putting the bottom joint in the linkage at to sharp of an angle which caused the binding feeling.

This picture shows the whole linkage and the two joints I'm talking about(steering column side is the left side of picture). Before my mod, the joint at the steering column had barely any bend to it. The joint on the steering rack side in turn had way to sharp of an angle. Because the steering column is basically pivoting through the firewall, adjusting the column up or down would affect the angle of the linkage joints. With the column adjusted all the way up it would in turn lower the portion of the column inside the engine bay making the angle on the joint on the steering rack side worse.



To fix the problem, I had to modify the connection to the steering rack itself so that the linkage would sit lower on that side and reduce the angle of that joint. On the steering rack side, there was no way to adjust the link lower. There is a groove around the splined shaft which the bolt for the linkage sat in. To lower it, I dremeled a flat spot down on side of the shaft where the bolt sat. At the bottom of the splines themselves, there was a lip that prevented the linkage from going past it which I dremeled down as well. That let me lower the linkage on the shaft a good 1/2 inch. I probably could have lowered it a little further but where I stopped worked out alright.

This picture doesn't show much, but you can see the flat spot I cut into the shaft to be able to adjust the linkage lower on it.



Lowering the linkage on the steering rack shaft reduced the angle of the joint on that side of the linkage. I also have got used to driving with the steering column adjusted a little lower than I would normally have it. It's not adjusted all the way down, just a little lower than my normal setting to help the angles out. Now I've got no feeling of binding while turning the wheel.

By lowering the mount on the steering rack side I didn't have to shorten my linkage.
