That is where your 'shimmy' comes from. It is caused by lateral runout that is a result from uneven torque.
100 ft. lbs. is the spec on yours. (103 actually, but 100 is goot enough)

If you just lean on them while tightening, you may have them tight enough, but they WILL be uneven. The first time you hit a puddle or snow with semi-hot rotors.... poof, warped and the shimmy is back.

That makes lots of sense. The right front rotor was the one that was warped and caused the shimmy.
I have the SLT aluminum wheels. They're real soft.
Now I'm gonna have to go get a torque wrench and check them all.
Thanks Tim!!!
