4x4 steering issue - won't return to center

[BILT4ME]

OK, I'm going to ask a couple questions that I am not positive of the answer here, but it's worth asking.

When the front springs were installed, were they installed the correct direction? Some springs have the center bolt offset to one end of the spring. I don't know what these are from the factory. I also don;t know if the bushings are the same on both ends that would even allow such a thing.

If the differential is now on a different center of the spring, your caster would be affected. Maybe the ideal location for YOUR truck with those wheels, tires, lift is closer to a +1° caster instead of +4° to +6°

It may be worth checking.

Also, did you install a new steering damper with it? If so, is the cylinder bad?

What does the book say for the correct caster spec for this truck?
