There are lots of bolts that have to be loosened and/or removed, as well as various connections and sensors. When I did my leveling, my truck wobbled 3-4 times every time it came to a dead stop and I had no driving modes. I took it back to the mechanic and he found that they hadn't fully tightened one of the ride height sensors upon reassembly of all the components. My guess would be something was not fully connected or tightened properly upon re installation on your truck. The only way to find out is to go back and check everything again. Good luck!
