Front to back. Vice-versa?
Likely you have a staggared setup... so that's not going to happen.
Me? I'm next taking it to a pro tire shop ) not a local independant (Joe's Tires) and having them perform a tire inspection.
How old are your tires? How are your wheel bearings? Did you try the 9/3... 12/6 method?
If evrything looked good... then I'm waiting on someone far more mechanically inclined than I to offer up some suspension diagnostics.
New tires might do the trick. Might.
Good luck. Report back... don't leave us hanging.
