There are a few different possibilities for why the steering could be hanging up.
Believe it or not the centerlink can be installed backwards and you won't realize it until later when you start having interference issues and tire scrub.
The other possibility is the steering box needs adjusted, it is made so that you can adjust the tightness of the gears inside, it sounds like yours is way too tight and you need to loosen it just slightly, now keep in mind that a little goes a long ways adjust it by 1/8 of a turn at a time, here is a link to a video so you can see how to do it.
