super stiff steering

Hey gang,

I recently converted from power to manual steering with a new 24:1 ratio box. But it takes the strength of three men to turn the wheel. I brought it to a suspension shop and they reported that nothing was blocking or binding, and all the ball joints and tie rod ends are new and greased. Also took it to the exhaust guru to make sure the exhaust wasn't hitting anything when I sit in the car. All clear.

Any guidance on this? Thanks!
