Violent Shaking in my Jeep Wrangler 04?

Hello!
I am fairly new to the Jeep Forum community I have a question. I recently purchased my first Jeep 2004 this past March. I haven't had any issues with it until today. It started shaking violently twice on the freeway going home and really scared me. I got 2 new tires on it yesterday. Don't know if maybe they did something?

I know pretty much nothing about cars/jeeps and am trying to figure out what to do. I am a college student and commute to school about an hour away in LA traffic, so shaking violently going pretty fast on the freeway was really scary. I am also really small and found it difficult to keep my steering wheel still as it was shaking. My jeep does not have a lift and really has no special additions to it.

Any suggestions/help would be greatly appreciated!

I'd start with checking the tire balance, particularly since you just put two new tires on it the day before it happened for the first time. Did it start shaking after a particular event, like braking or hitting a pot hole? If it happens again, is it at a particular speed?

Either crawl under it yourself and check for looseness in your front end suspension parts, particularly your trackbar, or take it to a shop and have them do it. See the sticky above on Death Wobble and take a look at the suspension diagram within it if you don't know what you're looking at. It is imperative that you get this corrected, as each occurance will damage parts more, and it could result in an accident.

Get an adjustable track bar and a new steering stabilizer.... That should do it

This is bad advice, mainly because you don't need an adj. track bar because you have no lift. And steering stabilizers have never been, and will never be, the reason you get a wobble or shimmy; nor will the fix a wobble or shimmy.

Lay under it first while someone turns the steering wheel back and forth quickly and then from full lock to full lock. Touch all the joints (be careful) on the front end and inspect for visible movement or and pops/clunks you feel. I just got done chasing a wobble gremlin and this is exactly how I did it. It's not complicated and usually requires you to tighten up some loose nuts and bolts (if there are any). Do this or bring it to a shop first before you buy anything, especially a new track bar.

And definitely get the shop to rebalance your tires. If its a speed sensitive shimmy, it's more than likely due to an improperly balanced tire.

Nope didn't hit anything or run any odd thing over. It just randomly started doing it as I would accelerate on the freeway. I think it was around 50-60mph merging.

Tire balance is definitely the first thing I would take it on for. Especially since you got 2 new tires.

Thank you, I am definitely going to take it back to America's tires and have them double check it. I don't know exactly how or what to tighten but ill see if my dad can help me out with it if its not anything with the tires. Thanks! -Anjelika

Also check your pressure. Tire store are notorious for over inflating.
Stock size use the door sticker, if they are oversized, lower them accordinally.

Since you are new to mechanical work and jeeps watch this video. It's a pretty good diagnostic of the Death Wobble and associated parts.
