Poor straight line steering control

[Lmackattack]

One thing I found the other day when installing new rod ends and metal servo arm were that the metal spindel ( part that holds the wheel locking nut.) that incerts into the plastic steering knuckle have lots of slop. I put some loc tite on them to better hold it tightly in the knuckle housing. I also removed some slop Buy installing a shim where at the top of the plastic knuckle where the steering pin holds the knuckle to the axel. Not a lot of slop there but it sure tightened it up so I have 0 slop there yet it has little to no friction in the steering. Seams the only place I have slop now is in the spring hanger but not sure I will be able to fix that....

I had the same thing with my Scania when I built that, with it all built per instructions it wandered all over the place as soon as I hit a bump. I ended up moving the servo for a direct linkage and moved the steering rod behind the axle for better ackerman. Reduced slop a heap and gave me heaps better steering angle.
