Question type: Maintenance & Repair
First post here, I thought I'd give it a shot to figure
out my situation.
I own a 2004 jeep grand Cherokee and at 30mph I
start to feel a vibration with steady pressure on the
gas pedal. When i let off the gas it goes away.
What could cause this to happen.

Possible u-joint in the drive shaft going bad, Is this an automatic?
Another cause for a vibration would be loose torque converter bolts, just 3 of them & easily checked by taking off the inspection cover and checking them. Can you tell what area it is coming from?

Not really, it happens at 30mph when my foot is on the pedal. I feel it in the steering wheel but my friend also felt it in the passenger seat.
Also check the drive shaft at the tail-shaft input at the rear of the trany and at the rear end, to make sure there is no play by pulling-pushing on the driveshaft. Check all the things I mentioned, go from there.

i have the same problem except at 80 mph
Yes, Cabaliero, check your drive line, vibration is probably coming from the rear drive shaft. To inspect the u-joints it is best to pull the driveshaft out. First checking the yoke going into the tranys tail shaft that there is no up and down play there.
But going 80 mph you may want to check you tires for balance also, may have lost a wheel weight or something causing a wheel to be out of balance.
I would have driveshaft shop bal check the front driveshaft. The u joints there are hard to tell if bad by feeling with hand. Its super common for rear joint of front shaft to be cause which can blow transfer case apart from vibration. Also sounds like a rear diff noise. Def dont ignore it.
I have a vibration when going in steady speed, a bit higher load or I speed up slowly. The vibration disperse when I either use the kick-down or slow down. This happens for the mostly in either 4 or 5th gear.
A vibration at any speed can be caused by the following: Tires having significantly different air pressures on the same axle example 1 front tire is 5-10 lbs lower than the other this will cause a vibration. Also it will pull to the side that has lower air pressure. Tires our of balance front or back Wheels out of alignment could be just front end alignment or even rear wheel alignment or both First check air and have shop balance tires. Also, make sure you are rotating tires regularly - ever oil change or at least every other oil change. Plus have front tires balanced 1 time per year. All of this should cost less then $100 to do maybe $150.
