DW and track bars

OK, so I'm going to start my quest to solve my DW issue. After reading many posts here I am thinking that replacing the track bar may be my first project if I determine that mine has issues. (Probably do tires, high speed balance and alignment before anything mechanical begins)

Should I go that route, what do folks recommend as a replacement? My Jeep is stock with 17" tires and is a DD and the most off-roading will be an occasional logging road.

So, I don't need (IMHO) the biggest baddest track bar that is out there and merely looking to see if there is something above OEM or parts store replacements that I might want to consider.

At this point, I'm not even sure if mine is an issue but want to gain some knowledge before I get too deep into this.

Thanks.......

How many miles? My the rod ends and drag link ends were shot at 60k. I didn't have DW but sometimes the steering would feel like it could start at certain times (hard to explain). Also, it would push if I hit a bump in a sharp enough curve.

Replaced with the Fusion4x4 steering set up and 100% fixed the issue. And Jeep truly drives better than at stock and 30k.

If you want to keep it budget friendly look at teraflex or rubicon express for some stronger trackbars.

When inspecting your track bar also inspect the bolt holes on both track bar and the mounting brackets to make sure that they haven't been ovaled out from loose bolts.

If you decide to have your tires rebablanced do what's called a "road force" balance on them.

Track bar is a good place to start, but keep in mind that TRE's and other items can cause DW. Check the mounting holes very closely to make sure they haven't taken damage. Also, increasing caster really helps.

I prefer the Core 4X4 track bar. It has a flex poly bushing on one end and a premium Johnny Joint on the other. This is like the "biggest baddest", without the price. It also comes with a "you break it, we replace it" warranty.

I would check tires first for balancing. That is a must do and the track bar may just cover up the Out of balance tires. I went with the JKS Adj. Trackbar. I have 2" lift so front end needed adjusted. Between that and new tires my wobble was gone.

Also, did you do a ball joint check? Lift the front end and check to make sure there is no movement in the tires by pulling and pressing on the wheels.

So much to check, many updates you cannot go wrong with just a matter of checking the basics first before you start adding parts to it. That is usually my mode of tackling these sorts of things.

I have something like 43,000 on my 2010 currently. Tires don't look terrible but they are dated 0811 so are from around the end of February 2011. As much as I hate to spend close to $1,000 on 4 new slippers, alignment and high speed balance, I would probably feel better knowing that my tires were new, balanced and in proper alignment before attacking the front end parts.

Thank you Sir. Yes the Core units are the cat's meow. The warranty is beyond reproach.

Namaste,

Allen

I will be getting this Core 4x4 TB when the time comes for my 16. I love the core 4x4 line-up. I wish they made Tie Rod and Drag Links... Why don't they Allen?

It is already a saturarted market. Plus they want to keep it a simple business model and in house. This way they can focus on quality product production. Spence had big dreams of a completely bolt on TJ longarm kit right until the launch of the JL.

Thank you for the question. Have a blessed and prosperous evening.

Well new slippers, a wheel alignment and high speed balance and after two attempts to exceed 50 mph I don't have any DW.

I haven't taken it out on the highway yet to get up into the 70's but so far so good. I am a happy camper that I don't have to start replacing front end parts yet!!

DW is as likely if not more so to appear at slower speeds as well. It is not triggered by speed but by a bump that upsets the balance of the front suspension. If the parts are worn or loose to the point that they allow the front to move from side to side it sets up the harmonic with the front axle moving back and forth.

One tech used a section of broom handle to run over and set if it set of DW on a vehicle. Hopefully, in your research you went through Planman's thread on DW and watched the video of a JK triggering DW just by running over a pavement bump. He was probably not doing much over 30 MPH.

My violent wobble was triggered at about 50 or 55 mph. A bump was not necessary, merely the approach of those speeds. The shaking was so violent that I thought that the front end would fall off.

As I said, I have run it up to about 60 so far and no wobble. A couple of weeks ago I had to pass a guy who was doing about 30 on a two lane road where the limit is 50. He sped up a little as I passed and as I picked up speed to pass the wobble began. It was very embarrassing to have the Jeep front end bucking around as I tried to pass. I finally got by him and pulled back in front and then had to slow down under 50 to get the shaking to stop.

Several local trips had to happen in friends vehicles because I was afraid that I couldn't drive highway speeds in the Jeep. Hopefully now I will be able to share in the road trips.

One of our local news channels did a story about Jeeps wobbling and supposedly there may be federal action coming against the manufacturer.

I did get before and after alignment numbers and I will post those FWIW as part of the story once I find the report.

If your vibration was triggered at about 50 to 55 consistently and once it started you were able to stop it by slowing down below 50, the it was definitely NOT DW. The reason it is called Death Wobble is that the only way to stop it is to come to a complete stop or nearly so. It is NEVER triggered just by a specific speed, but can occur at slower speeds as well as higher speeds. The video of a JK with DW on the Planman thread was at city street speeds.

The wobble (sometimes also referred to as a shimmy) that is triggered by just speed is almost always triggered by either tires or wheel issues. This vibration can be slight or even significant. A bit over a year ago I hit a deep pothole. On the way home on the Interstate when I hit a little over 50, I encountered a significant vibration that was decidedly uncomfortable. I simply slowed down below 50 and the vibration went away.

The next morning I drove down to my tire dealer and had the tires rebalanced. They offer free balancing and rotations on tires they sold. The issue did not come up again. I had apparently lost some of the stick on weights.

If you had a video of the vibration, you would most likly find that a tire/wheel balance issue is noted by the wheel moving up and down while the video of the DW in the referenced Planman thread shows the front axle moving from side to side.

I’m in the market for a TB. I have a shake I’ve had for over two years that is felt at higher speeds. But the shake is in the frame. I feel it in my seat and console when I’m driving. I’ve been thru several sets of wheels and tires and still have wobble. Finally called my local Jeep accessory and lift store and they were 99% sure it was a bad track bar. I don’t get any wobble in the steering wheel and it breaks smooth without any wobble in the steering wheel. Either going with the JKS or Core. Both are the same price.

Well not sure if it was true DW or imitation DW but the front end shook so violently that I thought I was in an earthquake. Regardless of what it was it appears to be gone as I got her up to 70 and the only issue that I now have is a huge noise coming from m light bar. Its loud but at least it doesn't force my Jeep off the road.

Reading this post as DW=dear wife and DD=dear daughter was pretty confusing. Then the pictures set me straight.
