when i am driving at or above 60 mph, i feel a shaking in the steering wheel.

tires are new and suspension looks good. i work at a dealer and i have had a tech look over everything. everything seems ok

worn out bushings ?

My first guess would have been tires that need to be balanced, but you said they are new. Maybe double check to make sure they are in fact balanced.

Only other thing that comes to mind is the driveshaft.

Did he check for warped rotors? Just a thought...

wouldn't rotors be felt when applied ??

i know all to well about the 99-04 grand cherokees and their brakes, so i do not think it is brakes,

how would the driveshaft affect it ?? how can you check for problems ??

check the balance on the tires again. Does the shaking go away as you approach 100mph?

I second that recommendation. You might have tossed some weight, or they were balanced bad to begin with. Another thing to check is "out of round", but that usually just gets worse with speed.

vibration felt, stays about the same, even when going faster,

sounds like an out of round tire. sometimes it's literally hard to get a f*ckin round tire these days. I've swapped out entire sets of tires before because of tires that simply are not round. a vibration that is at all speeds is almost a sure sign of this. if it's bad enough, you can feel it even at a snail's pace between red lights as a sublte up and down motion of the car.

it could be warped rotors only if the calipers are not releasing enough (in other words, warped rotors and sticking rotor(s) together.

also, as said a few times above, a tire being new has nothing to do with it being balanced. these days, a goofball attempting to balance it sometimes has nothing to do with it either

take it back to where you got the tires and be persistent until the problem is found.

worn out bushings won't cause a vibration, they'll only let another problem be more pronounced in some cases.

Your rotors are probably warped.

My car did the same thing at high speeds and more so when I applied the brakes. Get your rotors machined AND your tires balanced and that should fix the problem.
