could be a wheel bearing or a tie-rod but those are only a educated guesses Possibly something to do with your suspension, or it could be an axle. My family owned a van that did the exact same thing and it turned out to be the axle.
front end is worn out
YOUR FRONT ROTORS ARE WARPED. YOU NEED A BRAKE JOB.
Sounds like a motor mount or a transmission problem.......
buy a new car!
YOU CANT BALANCE A FRONT END. YOU CAN ALIGN THE FRONT END OR BALANCE THE TIRES. IF THE CAR PULLS TO ONE SIDE OR STEERING WHEEL NOT CENTERED MAY NEED ALIGN. IF THE CAR SHAKES AT HIGHER SPEEDS OR AFTER HITTING BUMPS MAY NEED WHEELS BALANCED My 300SEL cost $42.00 for a front end alignment.
It is likely a brake rotor has to much run out (warped). There could also be some problem with steering or suspension components.
worn front end parts (steering or suspension) could cause a car to shake when appling the brakes.
Check the front motor mount.
Front brake rotors are warped
This problemsounds like the tires might need to be rotated and balanced. the car might need to be aligned if the car pulls to the right when you are driving straight.
Both ends
Mine had a warped rotor and i had it replaced and it helped
