Steering stabilizer

Hello all!
I had my alignment done recently and the report said it's done but my steering stabilizer had a play.
What the hell is steering stabilizer? Did they mean the stabilizer bar? Or sway bar links?
Trying to figure it out because the truck is driving straight but the steering is not pleasant. Wheel could be a bit to the left and when I correct it a go to center it steers slightly to the right but if I go slightly to the right and then center it is centered. Feels like there is some play somewhere. So I'm trying to figure out which part should be replaced. I recently replaced both LCA and the ball joints on UCA.
Thanks!

 

Steering stabilizer is like a horizontal shock absorber connected to your steering linkage. Google will provide more pics and descriptions than anything I can add.

 

These trucks don’t have a steering stabilizer. Maybe ask whoever told you that.
