HAS ANYONE HAD A PROBLEM WITH THEIR CARS THAT THEY START TO SHAKE WHEN U REACH SPEEDS OF AT LEAST 60 MPH OR MORE? I HAD MY TRANNY WORKED ON AND AFTERWARDS THE CAR STARTED TO DO THIS.....HAD AN ALIGNMENT DONE HOPIN TO FIX THE PROBLEM, BUT IT DIDNT WORK!! IF ANYONE HAS ANY IDEAS AS TO WHAT THIS MIGHT BE, PLEEEEAAASSSSEEE LEMME KNOW! THANKS!

could be the wheel balance, tie rod ends, and like u said alignment.
To check tie rods, lift one said on a jack so the wheel is off the ground move it around and check if there is play. If no play, check next wheel, if yes, rod is dead. If its a wheel balance you would need to take it to a shop to rebalance the wheels.

Enjoy.

Mine did the same when I had the tires rotated a month ago, I dropped my car on neuspeed race 2 weeks ago and it stopped but sounds like it could be a wheel balance.

I think its wheel balance especially if you have rims they usually don't put weights outside since it would look like ****

It could be the wheel balance or uneven tread ware due to bad camber
