I am going to be doing the 9/16 grade 8 bolt switch for the TB and LCA. However, I run the BDS Cam Bolt kit instead of adjustable LCA. Should I even bother switching only one of the Front LCA bolts since the other one is using the BDS Cam Bolt kit bolt?

Wow! Wish I had found this a year ago. At the time, I hadn't thought of calling it a Death Wobble, but I can attest to that being a very apt description.

For us, it was a repeatable thing. I knew the exact place on the road outside our house to make it replicate. It was a harmonic kind of thing, if you got the bounce just right, at the right speed (about 45 for us), then the front end felt like it wanted to take off into the weeds but couldn't figure out which side of the Jeep to leave from.

The Steering wheel was a handful. If it hadn't been for two hands on the wheel the first time we felt it... I don't know we'd have recovered. So here's where it gets weird.

We take it to a trusted local shop. They tell us to replace the tires, because they are badly worn on the outside edge. Their inspection of everything else doesn't find anything.

So I'm thinking to myself... tires don't wear "funny" just on their own; something causes it.

We order new tires and have to wait for them to come in. During the few days we wait, I take an ingenious keyfob video camera and tape it to the bottom of the axle and get some great video of the problem.

Yes, the track-bar was loose, but in addition, the passenger side lower control arm was found with really bad bushings. The video showed the passenger side was absolutely violent when compared to the driver's side.

The problem now... we replaced the tires and I replaced the bad bushings in the control arm. The DW is now gone, but we can still pick up some shakes in about the same part of the road. This tells me I don't have it completely solved, in that the original DW has probably caused a lot more parts to get out of whack.

And the tires are already starting to wear funny, which is my second indicator that something still isn't right. Having read the first few posts in this thread, I'm now sure of what I need to go back and inspect, and I feel a lot more confident it's something we can fix.

I'll probably also print out the first few posts and take it to my trusted shop. They are good old boys, but that may be part of the problem too... good and old... and technology challenged. Probably haven't seen it quite this way before.

PS. This same thing happened to my Dad's 1993 Dodge pickup truck, with me driving. The Dodge dealership he takes it to found the problem right away and fixed it. No problem since.

So glad I found this thread. I have a 2011 stock Wrangler and went around the corner on PCH the other day and all of sudden the Death Wobble. I didn't know what was happening.

I have a full 100k warranty bumper to bumper. How should I proceed?

Read posts 1 and 2 of this thread: http://www.jeepforum.com/forum/f96/d...bbles-1052221/

Then, watch my 2 YouTube videos that I posted in the following thread:
http://www.jeepforum.com/forum/f96/d...ideos-1376201/

You will know and understand more about DW and your front end than your dealer techs.

It is rare that a dealer tech will know what to do. So, your warranty doesn't hold much value to fix the problem(s). You can try, but don't get your hopes up.

Last night as I was driving home, my jeep had an episode of death wobble. I can't recall if I hit a bump or it just went nuts on its own. I had to pull over to the side and completely stop the jeep to end the dw. This is the first time it's happened to me in my jk. Have had dw in my yj and tj.

I want to replace the bolts that planman mentioned. Where can I get them? Home Depot / lowes or do I need to order them from somewhere?

Also, what is the length of the bolt that is needed for the replacement?

This set replaces all 4 lower control arms and the front and rear trackbar bolts. If you make it part of a $100 order, shipping is free:

The second video is effective at illustrating various problems. Good job.

How much rotational play should be in the drag link. Mine rotates about 45 degrees about its axis. Is this normal or are the ends shot?

Rotational is required for the suspension to be able to cycle.

There should be virtually no up-and-down or side-to-side play/clunk.

Have you watched the 1st of the 2 Diagnosis Videos?

I have an 2009, 19,000 miles, that is going to my mechanic next week for the DW fix. I told him to follow your complete list, word for word. I ordered the bolts as you suggested, and would like to get a heavy duty steering stablizer. Can you recommend a source and description for this item? Also, are there any other parts I should order before the inspection/fix?

Your instructions for the DW fix are most appreciated!!!!!!! I experienced the DW about a week ago and was ready to sell my Jeep until I found this forum. Thanks again.

Make sure it's fixed before you put a new stabilizer on, otherwise it is going to mask the real issue.

Yes, it will have gone ALL the way through the check list before anything is replaced. Thanks for the comment.

I don't really have a specific recommendation on a replacement steering stabilizer.

The only exception would be that if you run Toyo Open Country MT tires that result in a hard drift to the right even with an alignment, you can offset this by running a gas charged steering stabilizer that pushes towards the driver side.

Otherwise, you could do a combination relocation bracket and new steering stabilizer from any number of manufacturers.
