crazy shuddering ?

ok so a few days back I was running through a construction site and ran over a series of bumps in a row.. Straight road, no incline... it started to shudder like the frame was breaking in half... I slowed down and it stopped when I got down to about 25 mph or so... I thought about it and wrote it off to maybe the TSB freaked out b/c of the short series of bumps and whatever...

well today on the way home i'm going about 45-50 mph and around a slight turn ran over a few bumps and again.. felt like I was going to lose control... WTF... anyone else having a problem like this? love this jeep but what the heck man... I had the recall for the TSB thing done months ago... It is weird how all of the sudden this has happened twice in a week. I've had the jeep for about a year, 13k miles and nothing until now.

HELP

I've posted before with this problem also... happened to me last summer, took it to the dealer & they asked me to re-create the problem, which of course, I couldn't. Scenario was about 40mph around a slight corner 7 hit a small pothole which sent the front end into a wobble, had to brake about 10mph to stop the shuddering...not sure what the answer is yet.

"Deathwobble" is not well documented by Chrysler though, most of the previous posts on it occur on lifted jeeps, not on stock suspension.

"Death Wobble" is really only a term used by us...and maybe some other enthusiast groups.

Basically, your alignment is out pretty bad and needs to be corrected. Once corrected, you are good to go.

Easy fix.

could be the ESP coming on over the bumps, but I would put money on death wobble.

It has nothing to do with the alignment loose bots, etc..., had mine checked & was straight as an arrow, ESP would & should not come on over minor potholes, there was no tire slippage to set it off.

From what I could tell, the bump is enought to set the coils resonating

Check trackbar tightness. Get tires rebalanced. Those are the 2 major reasons for death wobble.

Agree! Mine was trackbar related!

This seems odd for a stock JK though!?!?! You would think that it would have come off of the line good to go. However, I found loose bolts here and there when mine delivered...

feels tight in the front.. I did notice if you grab the track bar (the one with the steering stabilizer on it). It will rotate up and down a bit. I believe this is normal b/c of the ball joints on the ends. Then again, could be very wrong to have any play at all in it. Can anyone else confirm their front bar does the same thing... I don't see how that could have already developed a problem. I don't take it off road nearly as much as I would like to.

Thanks to anyone that can check theirs for me

That's not your track bar that's your tie rod and yes it moves due to the ball joints.

Definitely sounds like you were experiencing death wobble. Things to check:

alignment
wheel balance
front track bar bolts for tightness


Best thing to do is have a friend sit in the driver seat and turn the wheel rapidly from side to side. While he/she does this get on the ground and watch all of the bolts in your steering components to see if there is any play (ie. bolts or the bushings that surround them moving from side to side).

If you do notice any play then tighten 'em up.

Use the search feature and you will find about a gazillion threads documenting the cause and effects of death wobble and how to get rid of it.

Any Jeep with loose steering components and or a bad alignment or wheel balance is susceptible to death wobble. It's just the nature of the beast.
