Suspension Chirp?

[spudz29212MKIII]

Anyone else had this. It is a high pitched quick chirp, you can hear for a split second. Only when I go over repeated bumps such as railroad tracks. Kinda like a chain noise, or a loose nut and the washer jumps real quick. (idk its hard as hell to explain a noise in text) Bro said a vast amount of reasons. Bushings, old struts, needs a grease down ect ect. I was just thinking struts gotten old, and the quick up and down on the suspension caused a chirp noise.

Another thing, car vibrates horribly on highway. Now what im 99% sure it is, is this. My brakes locked up one day and now my rotors are warped, and you can hear the pads scuff the rotor a certain point when you coast. Jacked up car and spun the front tires and they would drag/scuff only at a certain point on the disc. I am about to change them over the weekend. Just wanted to know if yall agree with me.

(I mean vibrates!, lol the damn stick shakes like hell and the steering wheel shakes like hell)
