I know there are a million threads on this but normal culprits have been ruled out. Track bar is relatively new and bolts are exceptionally snug. Bearings are both solid and checked by mechanic as well. Stabilizer generally doesn’t come into too much play but also solid and relatively new. The only thing that isn’t relatively new is the upper and lower steering shaft wondering if the bearing on the lower shaft that is attached to the fender wall could be the issue. Tried shaking it by hand, doesn’t really move. Happened at usual speed of around 30 to 40 mph.
