wierd shaking at high rpms

[G33k]

ok so today i was driving and these 2 cars crashed infront of me once i got the chance i went around but when i did i sorta got on the gas and when i let go the car was shaking and sorta bouncing it felt like a had a flat on the front driver side
but when i checked everything was fine
just wondering if anyone had any idea of what it could be?

what significance does the cars crashing have? are you saying you slammed your brakes?

Trying to understand. So you hit the gas and took your foot off the gas but you did not touch the brakes. If this the case check mounts could be motor or trans. if you applied the brakes, you prob need new or smooth out your rotors.

I think u made ur tires "square" by slamming on the brakes. U probably have a flat spot on ur tire.

i didnt touch the other cars
and i didnt slam on my brakes
when i went around i put it into 1st and took off... i hit around 6k on the rpms and let go of the gas and then i felt it
it also does it when i downshift sometimes
it feels like its coming from the tire and it looks a little low so ima try putting some air and maybe check if the lugs are tightened all the way

i was just trying to lay out the scene for you guys. i was tired and really have no idea why i added that

idk maybe you have crappy tires. How about pop the hood and open the throttle manually see if the motor shakes roughly could be bad motor mount

i have a similar problem but mine only shake in 2nd and 3rd it less noticeable in third and it only shakes like from 1800rpms to 3900 rpms and Ive changed my axles left and right and even put in a new diff but still does it mount look good in the back and the front is a solid poly mount .
any thoughts on what it could be it not a wheel problem they are tight and new and balanced . all the mounts are close to new about a year old .

could it be the half shaft bearing???
it stared out of no where in the high way while i was slowing down for an exit
after that its had that shake its gentn on my nerves
