Bouncing rear? In my 98 Trans Am I feel a bouncing from the rear like if I go up a hill or just typically driving down the road I feel the rear bouncing or shaking....its a weird feeling
Low speed vs higher speed makes quite a difference. Even worn out shocks can function well enough to dampen over a speed bump. If your shock fails to do even that, then they are extremely dead and should have been replaced a long time ago.
How many miles are on the car?

There's only so much going on back there. Two trailing arm, a panhard rod (6 bushings total), coil springs, and shocks. Shaking could be something else, but bouncy that's got shocks written all over it.
Do you have stock suspension? A lot of time, people use the stock length bolts on after market parts and they are not long enough and the nuts fall off the bolts. I made that mistake when I installed my tq arm and the nuts eventually wiggled off leaving me with the bolts just chillin, every time I hit the brakes it felt like i was going to endo. From that point on.. hardware included please!

I do have stock suspension. Like my u joints are brand new so I know thats not making my rear end bounce and my shocks....well I don't know but I can assume they are good since the car only has 50k miles

Verdad Gallardo Get the rear up in the air, take the wheels off and nose around. Pull the sleeves down on the shocks, look for leaks, check the springs look for any signs of damage. Take some pics, and post them up.

Everything seemed fine but I found a leak in my pinion seal.....it has been making a clunky noise when I change gears or step on the gas, its not my u joints I checked those out.
Anyone who's read the threads on ls1tech suspension section for the past 10+ years or so until now would know the stock shocks have really poor damping. The shocks don't have to be blown to have poor damping control. Yes you will probably notice a lot of bouncing around in the rear with the stock shocks. New better shocks can fix this issue like Bilstiens or Konis. You can go with a cheaper set that some people around here prefer which will help a little but in the long run you will just have the same problem as they will soon wear out as well.

You might be right because if I drive like a grandpa it feels fine for a while, however, if I take off like at a drag strip as soon as I go a steady speed it will feel all bouncy and shaky for a while then it settles out and smooths out but still kinda bouncy....
your car has only 50k miles?
pretty good!
the only problem is that, with the factory deCarbon shocks, they really didn't amount to much when it came to performance.
You driving like a grandpa actually is a blessing because really, the factory deCarbon shocks only last about 20k-25k miles and that doesn't include the amount of years that they have been on your car, so your shocks have been blown for years buddy.
so at this point, anything would be better than what you have right now.
