Its an 05 Laredo, 3.7 Qt1. Ive only got the JBA front leveling spacer with stock size AT's and Spidertrax spacers on a set of XK wheels. I did try turning off the traction control and it still made the noise. My first thought was that it sounded like when the the traction control kicks in when driving in snow. Def sounds like its in the front end. Like I said its only when the wheels are turned, and it seems like the steering wheel has to be turned beyond 3/4 turn.
