High Speed Pulsation

[deja_vu1344]

So last week I skidded out in the snow in my 2005 Corolla LE Auto and drove into a curb at approximately 15-20mph. The very next day I went ahead and got an alignment. The shop adjusted the toe but mentioned that the caster was not within specifications and could not be adjusted. This is my first alignment so I don't know what the caster value was before my accident.

So after the alignment my car drives normally under 40mph, but as soon as a pass 50mph i can feel a pulsation in the pedal that was not there before. It is most noticeable when I coast. I can feel the pulsation/vibration through the pedals most obviously. It is difficult to describe but it almost feels like I'm driving a rear wheel drive car with a bent drive shaft.

There are no check engine lights and the car accelerates and breaks normally. There is no vibration in the steering wheel and the car drives straight. The tires were also recently rotated and pressure adjusted.

I'm running out of ideas please help me toyota nation. Any advice would be appreciated. Thank you.

Did you slightly bend a wheel?

Oh, yea, check for a bent drive axle on the side impacted.
