Hit Bumps, VIOLENT SHAKING, death wobble?

Driving down the road hit a few bumps, the front end shakes violently. I have to slow down to about 40 then it goes away. I can stick my head out of the drivers side and see the front wheels bouncing. It mainly happens when I hit a bump on the PASSENGER side.

The whole front end and rear end is stock/original (shocks, springs, axle u joints, etc...). I know alot needs to be replaced, but any other ideas, to rule out anything else would be great.

I have visually checked and have found no broken or cracked parts.

New steering stabilizer? That might just cover up the problem but it could work. Maybe new tie rod ends, drag link, etc.

Have someone turn the steering wheel back and forth while you watch each tie rod end and ball joint. You should be able to tell which one is messed up.

I know the tie rod bushings need to be changed, cause the ones in it are the original. I will get to working on it this evening. Start there and see where it takes me.

Thanks

Alright, I jacked the front end up and had someone turn the steering wheel. I could not see anything that would be out of the ordinary with the tie rod ends. WHAT EXCATLY AM I LOOKING FOR?

I tried rocking the wheels top to bottom to see if something in the hubs were loose and they were solid, no movement.

Tie rod, drag link, sway bar, trac bar, all are in good shape and not bent.

Could it be something just as simple as bad shocks?

Don't jack the front end up, leave it sitting on the ground so that there is a load on the parts. What you are looking for is "slop" in the tierod ends - the socket starts moving before the pin.

I just solved a front end shaking violently problem. Turns out my shackles were not torqued properly allowing them to move side to side.

I am assuming the socket is on the top and the pin is the bottom piece?

Get a big *** pair of pliers. Put them on your tie rod ends. If you can sqeeze them and they move up and down, then you need new ones.

I'd assume you need new ones since you said it was all stock. I just ordered the Rugged Ridge HD Steering kit and a skyjacker stabilizer and it got here yesterday. I had my girlfriends birthday party last night and didn't get to put it on, but the parts look pretty stout. I ordered it from Autoanything.com for 202 shipped.

There in good shape, about 80-85% tread left and no bad marking on them. All the weights from balancing them are on them to.

I will try that when I get home this afternoon. I just went out to the parking lot with a co-worker and had them turn the wheel while I looked. Everything seemed to turn at the same time. But I did notice that there seems to be some spacing, so I think the big *** plier thing would help me out with seeing if that could be a problem.

after you check your tr ends, check your ball joints. from the side of the wheel push the top and bottom in and out to see if it can move a little like that. try to lift the wheel while someone looks at the ball joint to see if there is play. i just solved my severe death wobble by changing all 4 ball joints, it was hard to tell with the wheels on, but once i pressed them out, my old ones were absolutely toast.

Start with the steering stabilizer....My Yj would wobble after going over railroad tracks so severely I would have to pull off the road and slow to a stop. A heavy duty stabilizer solved the problem.
