Why steering wheel shudder when braking at 60 mph plus? on 2004 Ford Freestar

Machined front and rear rotors and replaced rear pads but no change. Front caliper guide pins were a bit sticky so replaced and greased but no change. New tires on front. No shimmy otherwise

You would need to check all the suspension bushing make sure the suspension struts are OK but also check the front disc/rotors for run out even .002" to .003" out of true will cause a brake shutter.Perhaps the where the brake s=rotors seat has rust under it. Try rotating the tires see if the problem changes. The bushings or sway bar links should not be loose or they would rattle. Look at www.rockauto.com they usually have good illustrations of the parts so you can see what the part looks like.

How tight are the stabilizer bar bushings supposed to be?
