Ha dthe Gt out on the highway today, and when ever I got above 75MPH the steering wheel would really shake and the steering felt floaty.

I took a video of the steering while it was doing it. which can be viewed here http://www.ghettosled.com/steering/DSCN0921.MOV
What should I be checking/fixing?

oh great, your steering is all over the road, and your taking video? Deathwish?

Did this happen all of a sudden, or has it always been that way? what shape are the tires? Shocks? Ball joints?

Could be a lot of things. Mine does the same thing. But I know I need shocks, struts, lower ball joints, Tires, and and allignment. I need brakes on the front too. but thats not why mine wanders. I got myself a busy Thanksgiving weekend.

1st time I have had it above 75 since buyingit, Tires are good, and I had just had the pressure checked (oil change and such), It drives in a straight line with hands off the wheel even thought it jumps around. Shocks/struts seem good.

I know...I know...I know! See the temp guage?
Your car is running too cold!!!!

Seriously now, 4 wheel alignment, front tire inflation, worn dogbone (I was told), steering stabilizer (if applicable) and last but not least, worn cradle mounts.

Mine did it bad until I inflated all tires evenly. Oh, did the alignment and it may have helped because the effect of under-inflation in one of the front tires causes less of the problem than it did before. Now it is mild if it shows up. Next, dogbone. Last, cradle.

Ain't this car fun!

Lol That normal operating temp for my car, only seen it higher than that once, after 2 hours of Stop and go cruising.

I figure it's bushing being rotten.

I have an '87 GT and had what I believe is an identical problem. Solution, if yours is not an '88. Replace the front steering stabilizer with a new Monroe SC 2943. In fact, get two. Buy the stabilizer doubler kit from Rodney Dickman and install. A very easy job. Then get a 30 lb. weight from a weight set and bolt it to the underside of the donut spare. It then takes up NO room. Do not just set it under the donut spare because it will jam in place as you try to get the spare out. I have done all of the above with remarkable results. My GT is rock solid up thru 110 mph. I'm afraid to go any faster.

Mine is due to loose tie rod ends (just getting old), old steering stabilizer, and until recently, unbalanced tires. If its been a while or never been done, get your tires balanced. Any tire shop can do it. Cost me $20 and made a world of difference.
