Play in the handle bars???

I wasn’t sure what terms to search for this, but I have a lot of play in my handle bars. My bike is a 2014 renegade 1k. It has about 1k miles on it. Lots of mud and rough stuff…
Basically sitting on the bike, you can turn the bars a fair amount both ways before the tires move. It looks like it is the steering shaft bearing/bushings.
Anybody know of any threads out there to help with this? Any tips for things i should change when i tear everything down to fix?
