My car start vibrating above 70 mph and also when I applied brakes at that speed. What could be wrong?

I just bought this car yesterday from another person. I already changed both front tires and balanced it. it is front wheel drive. Could it be axel or brakes? any suggestions?

Possible causes of vibrations:

1. Bent rims.

2. Tire out of round or improperly balanced.

3. Worn out struts, shocks, or steering components.

4. Over tightened wheel lug nuts, especially stamped steel rims.

5. Out of alignment.

6. Mud or other material stuck on rims.

7. Badly warped front disk brake rotors.

8. Axel shafts worn and/or bent.



If you feel the vibration in the steerings wheel the problem is in the front. If you feel the vibration in your seat the problem is in the rear. If your rotors are warped, you will feel it at slower speeds under hard braking. Bent rims or out of round tires you should feel a slight wobble at 10-20 mph.

Have the front end checked for worn or broken parts ASAP as some bad parts in the front end can cause accidents and/or breakdowns.

Your tires need to be balanced and your wheels aligned. If that is not it then you have a bump in your tire, but generally it is the first 2. Should be a cheap fix.
if you just got your tires balanced and changed... the mechanic might not have tightened one of the caliburs completely...which has to do with the brakes..
my assumption is that your car need wheel balancing or the suspension system is poor
I have had the same problem, there can be various reasons, the first is obviously the tires, if those are new then the ball bearings are faulty, check those out..
If you have a relativly small car, it is going to vibrate at high speeds. Speed limit laws were made for a reason. Try getting your wheel allignment checked out and your tie-rods (It might be spelled tye-rods - I'm not sure)
it doesn't sound like there is anything wrong with your car - if i were you I'd go to the doctors - its obvious that you have %26quot;Wobbly Eye Condition%26quot;...
could be warped brake rotors if it has disc brakes.
your brake rotors have excessive lateral runout(they are warped) from making stops too quickly, causes alot of heat on the rotors.they need to be either machined or replaced if they become to thin-GM Technician-
