Exclamation Oversteering issue

So I've been having this issue for a while now...but only able to really diagnose the symptoms yesterday while driving back from the mountains.
It's that my jeep is oversteering on curves and turns. I have 31's w/ no lift. I've checked the air pressures, the bolts where necessary, and made sure that everything was greased. Anyone have any suggestion or questions on how to best solve this scooby doo mystery?

oversteering as in the rear tires are sliding around the corners?

First do a dry steer test as shown below to determine if you have any looseness in any suspension or steering components. Then jack up each front tire slightly off the ground and using a pry bar or shovel under the front tires, see if there is any slop in the ball joints. (not so much up and down, but rather in and out from the side). When you said you checked air pressure, I'm assuming it is around 30psi.

Dry Steering Test

Do a dry steering test by having someone sit in your Jeep (with the tires on the ground) and continuously turn the steering wheel back and forth from about the 11 to 1 position while you lay under the front end and watch and feel for any lateral play in any steering or suspension joints. Check both track bar ends, the tie rod and drag link ends.
Although rotational movement in the tie rod and drag link is normal and necessary, there should be no end movement at all in the joints. There also should be no movement in the track bar ends.

I'd take it into a competent alignment shop to see if the axles are square to each other and to verify whether or not the toe-in and caster angles are within spec.

Does this problem seem more or less depending on which direction you are steering, or is it the same either direction?

well after driving down from smokey's it's either direction...but I was told that my steering stabilizer wasn't adequate for my size tires. would that have anything to do with that? 31's with OEM stabilizer.

The steering stabilizer is not at fault, and the steering stabilizer is more of a steering damper for isolating the steering system from bumps and jolts on the road. Its job is less steering stabilizer and more jolt/bump isolator.

You could drive without a steering stabilizer entirely and not have any noticeable issues or differences if everything was tight and aligned properly.

As suggested have alignment checked. Larger tires decrease castor angle. You may need adjustable castor bolts

To be sure, it's taller suspension lifts that decrease the caster angle (and shorten the wheelbase)... bigger tires don't.

I've had my alignment checked several times..they say it's well within specs...is there a chart that would specify what the alignment should be if factory specs aren't correct?

Factory specs are correct on a Jeep with no lift running 31" tires. Did the alignment shop check your front and rear control arm bushings?

Sorry i'm just now getting back to y'all...had a busy week on the vomit comet.
To answer your question, no...they placed it on their little machine and that was it.

Do you have a sheet?

Did this just start, came with changing the tires or gotten progressively worse over tine ?

Just took it over to Just Jeeps in Knoxville, apparently by Ball Joints are worn considerably & need to be replaced.
