Comparing to the old box I'd say 50% easier steering left and 50% harder to the right. It steers way too easy to the left and just slightly easier than manual steering to the right. this is not just from center either, steer all the way to the left easy and as soon as you start turning right it's harder and vice versa.


Any idea what would cause this? Worse case scenario I'll just reseal my old box but would like to fix this one if possible.
The o-ring on the end of the pitman shaft is leaking badly. It's not allowing part of the box to pressurize and essentially reducing the power assist when turning right.

You need both boxes rebuilt. One due to the external leak, the other due to the internal leak.
