I put custom wheels on a number of f 150s and they all shake the steering wheel at 65
I know the new rack and pinon steering has something to do with it
any help would be great

 

What size you running?

I have '01 SCrew 315/45 22" Kuhmo and I get the shakes from 45-55 mphs. All 3 tire guys said "tires have bad spots and they need to be smaller". I've been told no bigger than 295/40, but recommend 285/30 for good ride. Since they run $1k a set I'm living with the shakes!
