Hello all, I’m really hoping I can find someone here that has had this issue and has found a way to fix it... so I have a 2010 legacy gt and with in the last few months I have noticed a shake, shimmy at highway speeds. My first guess on a fix was tires out of balance... switched outa the wheels and all and it’s still there... second was brakes and rotors... switched them out still the same... is it possible for weak lower control arms to cause this?? Appreciate want help! Sick of this shake
