Beware, Your alignment is cheap. Don't be surprised if they don't find $1.5k in parts and repair you need to finish the deal...guess what...you don't need it or them.

I know this sounds simplistic, but make sure your tire pressures are spot on. I had the same shake (between 73- 79 mph) and thought I would have to live with it.

The previous owner had spent a lot of money chasing the same shake, to no avail. I replaced the front tires and had a dynamic balance done and it helped a little but it would still show up now and then.

Back in March I brought the car out of storage and double cheked all systems and made sure the pressures were correct, and set out to take a short trip.

Watta ya know !! No more shake (except a little flat spot vibration). It's now shake free up to 110 mph.

Also make sure a belt hasn't twisted in one of your tires.

Good Luck !
