Steer wheel play

[Kgaddy]

Hello all, I’m sorry if this isn’t posted in the right section but I couldn’t find any results for the problem I’m having. 
So a little bit of back story.... I have a 2005 Silverado 1500 2wd with 180,xxx miles on it, It’s a good old girl. I recently had a lot of work done to the front end, new rack and pinion assembly, new coils, shocks, spindles, new ucas, new upper ball joints and tie rod ends. I had a shop install on the parts because I don’t have a driveway to work in right now. All the parts replaced were stock oem parts, so well worn out. The truck rides great now much more controlled and steering feel is firm. But I noticed there is about an inch of free play in the steering wheel ( no resistance, no moving the wheel in the free play). 
What do y’all think it could be? I checked the intermediate steering shaft for play and it is moving with the u-joint at the rack and pinion. Can the gear box be adjusted? 
Thank y’all for your insight. I don’t just want to fire the parts cannon in vain. Again thank you for all the help!
