as you can see in the write-up its a super easy fix that takes a few minutes. That being said, as mentioned above, the crash bar has no impact on steering. Did you install a lift as well or just the front bumper? Did you wheel recently?
Steering changes are usually tied to two things.
1-Tie rod damage causing a change of the "toe" distance and slightly shifting of the drag link (usually occurs after hitting the tie rod on something)
2-change in front end ride height. This is after adding a bunch of weight and lowering the front of the vehicle or adding a lift and raising the front of the vehicle.
