With 302K miles on a 2014 SR5, I've dealt with the wheel shake issue repeatedly. Road force balance is a must. The more aggressive the tire tread, the more important this becomes. If this shake is allowed to go on over extended time, you will wear out tie rods. When this happens, you will get steering wheel shake when braking from 60 or 70 down to 30 to 40. It's on the level of a death wobble and it is not cause by rotors. Tires just a bit out of balance, brakes grabbing the rotors and the whole violent shake starts. Inspection by a top drawer independent mechanic revealed slight wear on the inner tie rods. Outers were already replaced. New tires cleaned most of it up. New inner tie rods going in when mechanic returns from vacation as there are special tools involved to remove and install.
