my left front has a bad vibration between 60 and 70..i think its the pitman arm but i dont wanna change it if its not..the guy i bought it from just had the tires put on so im pretty sure they balanced them but im not sure
If the pitman arm is loose, you'll have freeplay in the steering and possibly wander unless there's a slght pull to on side. When there's a vibration like that, it's usually tire balance, out of round tire or bent wheel.
It owuldn't hurt to check the front suspension to see if anything is worn. Some parts can cause premature tire wear. Have someone turn the steering wheel back and forth slowly, engine off, and inspect all linkages, steering box and upper shaft for looseness.
with a vibration at a specific speed, the first thing I would suspect would be a tire balance issue. I had a set of "el-cheapo" tires on my Malibu, and those things would need to be rebalanced every 1500mi without fail. FWIW Belle Tire only charges $9 a wheel to rebalance them, and since you know what wheel is shaking, you only would need to get one checked. You could also try and rotate the tires, and see if the vibration follows a specific wheel.

Reason: added jsuthers
Does your vibration diminish somewhat when you turn your wheel one way or the other at these speeds, like say, when changing lanes?
no not really some roads it dosnt do it on as bad...but i asked him last night and he said its always done it but im still gonna get it rebalanced just to make sure cuz its a cheap fix..and to everyone thanks for all your help i can fix stuff no problem but im not as good at figuring out what it is and this forum is awesome
when you get it rebalanced ask them if the wheel is bent if they don't tell you, they should be able to tell while balancing it.
