I have a 2018 Zforce1000 with about 1,400 mikes on it. If the engine is off I can move the gear shift through all the gears easily. If I start the engine the shifter won't move out of park, I can force it with some effort to H, N or L but then it is stuck there. If I shut off the engine it will move easily again. Any thoughts?

Hey Group, need some help here. I have a 2018 Zforce1000 with about 1,400 miles on it,  2.5" lift and 30" tires and we ride pretty hard on a lot of rocky terrain. On our last ride I noticed the steering getting a little notchy and seemed off. Then I started having a delayed steering response and finally no steering at all - steering wheel spins but the wheels don't turn. I figured a blew out the rack with the bigger tires but when I removed it today and turned the shaft on the rack it works fine. Going to check the u joints and shafts next but wanted to see if anyone has any other ideas. Thanks!
