Rep Power: 303

I'm not sure whether I need to get an alignment or get my tires balanced.

My issue is when I accelerate abruptly the car pulls to the right.

When I brake firm I feel vibrations in the steering wheel. If I brake firm slightly turning to the right the, I have no vibrations in the steering.

What could this be?

First things first, check your tire pressure to make sure you are inflated properly. Underinfaltion or overinflation of tires will cause a pull to one way or the other. If they are fine, then you might need your alignment checked.

Now with the vibrations, are they happening at high speeds or low speeds? Most likely your rotors are warped or just need to be turned. Check everything out.

The vibration is at high speed braking

Well, I have the same vibration at high speeds, so I think it is normal to a degree, but to much, have your rotors and pads checked.

I used to have that vibration, but it was because one of the leds had fallen off my rear left wheel. After I bought the new tires and rebalnced the wheels, the problem went away.
