Can wheel alignments makes the steering wheel shaky when stepping on the break
Sounds more like the rotors need to be turned.
Sounds like a brake problem
Wheel alignments can make the steering wheel to be shaky when breaking. Other common causes of a shaking steering wheel include bad tires, warped brake drums or faulty front ball joints.
No. take it back immediately, they screwed something up. Otherwise it would have been doing it before the alignment.
No, when you get that shake/vibration only during braking then its because the rotors are warped and need turned down or replaced.
