Shaking in the front

When I accelorate or brake sometimes the whole front end will start shaking badly. But it will stop if I slow way down then coutinue driving it will be fine for a while. Any help will be great.

had death wobble in mine the whole life of the car.. finally swapped zj's and the other was great, had so many other problems.

How to know if its DW (death wobble) is it scares you to death!

Check ball joints, steering damper for starters. Like midnight says search the zj forum for Death Wobble. I hope you get it on the first shot.

Death to Death wobble!

I replaced my shock absorbers and then got the death wobble, go figure. I then replaced my tires, next all the bushings for the front sway bar. This seemed to really give my steering wheel such a nice and firm feel that greatly improved traction somehow. I went about 2 or 3 weeks without one wobble incident and it came back abruptly. I then replaced the steering damper (looks like a shock too) and still it wobbled. Finally, I took my smartphone video camera and laid it under each joint in the front end and turned my steering from one side to the other. The tracking bar ball joint was clearly bad, but I got under the Jeep and really got crazy trying to shake each joint and they all seemed firm. The ball joint is just below the power steering pump and has a grease fitting. My video showed that the arm from the steering pump assy. started to move, then the tracking arm moved after about a half inch of travel. My Jeep really feels like new, after all the other parts I really enjoy driving it again. Every part I mentioned were especially easy to replace. I must point out that I had to use a puller to get the damper off, any other way failed and I busted a few knuckles too.

In a nutshell, my problem was the tracking bar ball joint. You have to buy the whole bar ($67) to fix it, but it is so easy to do and of course the place I looked. Personally, I am glad I replaced the other parts, it really drives well now.

Check the track bar mounts for tightness. If they are tight, I'd go ahead and swap out the track bar AND the steering damper. It's cheap fix, for starters...but there's no guarantee this will fix it. The odds are in your favor, though.

Track bar was the first thing in my ZJ to be fixed along with the steering damper. Like old frog says, no guarantee. I still had it for life DW is a crazy thing. Glad to hear your loving the drive again, they get so sloppy with age and they are such a wonderful truck.

Wobbles Wiggle but they won't fall down

I have a 94 ZJ and the only change I ever made was to put 235 tires on it. That was back in '02, but the wobble didn't start until around 190k and I finally fixed it. I am at 198k now. I assume that many of the wobble issues typically occur in vehicles with lifts or similar type of alterations that lack stability, or in older daily drivers like mine. Just a guess though. I am back to highway speeds again.

Well i replaced the steering stabilizer and that helped alot. But i can still feel it wobbling a little. Their are 3 rods under their that are all connected and i can grab one and move the whole setup. Dont know what the rods are or if where their connected together they could/should be replaced.

That's your tie rod, drag link and track bar.

There's a good pic floating around highlighting each one. I can post it when I get home from work if no one beats me to it.
