Re: Front end shimmy
Torque is very important but not my first thought.
My first thought is that the rotor(s) is not properly seated against the hub. It is very easy for a piece of rust, dirt, or corrosion to get between the hub and rotor when they are being installed. It is important to be sure all contact surfaces of the hub, rotor, and wheel are all clean and clear of any debris.
Only after you are sure everything is proper, then torque the wheel bolts in the proper sequence.
