Wobble from 45 to 55 mph
 
I have fought this wobble since I have had the Jeep and everything that I have tried (that has been suggested on other threads) has done nothing to fix this wobble. I have had my tires balanced twice, ball joints checked, track bar checked, and all bolts that I can put a wrench on are tight. I have a fairly new steering stabilizer (bought late last year).

Both times the tires have been balanced they said that I have a bent wheel. So I threw it on the back to see if it would help and it didn't. Keep in mind this is at two different shops. I don't know where to go at this point other than take two wheels off of my dad's Jeep and see if it fixes the problem.

Background info on the Jeep:
2004 Wrangler LJ with 4.25" RE Superflex lift, 1"BL, Currie tie rods/drag link/track bar, 35x12.5x15 Goodyear Wrangler MTR Kevlar, and 15x10 steel wheels.

Here is a picture of my setup:http://i1092.photobucket.com/albums/...ps22ab6281.jpg

Thank you in advance!

How many miles on the tires?

Maybe 15,000. Just did a tire rotation with a balance a day after. Last week

Gold Miner 03-26-2013 06:44 PM

Not likely the tires then.
How did you bend your wheel.... hit something with it, pothole? If the wobble symptoms occurred shortly after that incident it might be easier to narrow down.

I dont know how it was bent. They said that the very first time I went to get my other tires balanced. Ever since then I made sure that rim was on the back or the spare. I believe the PO did something to it. They never say anything about the others and always zero out.

So I know you've already done this but I had EXACTLY the same issue on my 06 LJ Rubicon..........I thought for sure it was "Death Wobble" and read all the threads, and was underneath the Jeep checking everything at least 5 times....there was nothing out of the ordinary.

I had the tires balanced, then Road Force balanced (per Jerry's suggestion) and still the shimmy between 48 and 53 and only on certain roads......I was stuck!!!

I read another thread last week and it said that if the wobble/shake/shimmy....whatever was always at the same speed then the issue was almost certainly wheel balance. so.........I took it back to the tire shop that did the RF balance and asked them to check it and sure enough the wheels that were balanced just a few weeks ago were off by an ounce and 1.25 OZ on 2 different wheels.............new balance and it rides like it's on glass......Smoooooth!!!

Not sure if this is your issue or not but after everything else this is what it was for me....good luck!!

Ok. Im going to take two rims and tires off of my jeep and put them on my dads jeep and vise versa and see if it affects either one. I know it is a little drastic but this will tell me right away what is wrong. Ill post what I find.

Marcwakefield22 03-26-2013 06:58 PM

Also, make sure the tires haven't worn weird. And check everything to see if all the components are ok. It happened to mine because the tie rod was just slightly bent.. Then I found out everything on the underside had to replaced because it was all wrong. But it looks like everything has been replaced so just make sure nothing is bent at all

Gold Miner 03-26-2013 07:32 PM

Another thing to consider concerning balance: Caked or dried mud/clay on the inside of the wheels. This can temporarily throw the balance off, sometimes pretty bad... especially if it's caked to one side.
Looking at your pic, the inside of the wheel pictured looks clean so you can probably rule that out if the rest are that clean. That's always the first thing I check if I have a shimmy or wobble out of nowhere.

Kota7x 03-26-2013 08:04 PM

I just got back from driving it after swapping tires. Both cars did not shake :banghead:. But i did see that my drag link on the LJ moves up and down (will get video) and the drag link on dads TJ does not move. Could this be the culprit?

Kota7x 03-26-2013 08:52 PM

Here is the Video:

I do think it is my Drag link. I can watch the tire move back and forth when I move the drag link.

IMO.... yes!!...... anything that is moving that shouldn't be is suspect!!

Death Wobble Cure | Jeep | Front End Shake. I have it on my 99 TJ, tires are fine so I'm doing the front track bar and stabilizer along with the track bar bushings. The web address talks about death wobble and he has worked to eliminate this problem by using his kit as it has better (stronger) bushings. This article goes on to really explain death wobble and what can be done to cure it. Look up Kevin's off road for the article about death wobble as he explains it better than anyone else.

lynn 03-27-2013 08:34 AM

I had the 47 - 53 shimmy.
It twice blossomed into DW under certain conditions.
The cure for mine was replacing the front LCAs with new arms, Currie with Johnny Joints.

Sounds a lot like my issue on my 99 TJ w/ 4" Teraflex lift and 35" MTZ's. It's not "Death Wobble", but a "shimmy" that occurs in the 45-50 mph range. Going over bumps does not create any increased effects (like death wobble would) and the shimmy is sporadic in nature (doesn''t happen all the time). You can speed up or slow down and it goes away.

All of my control arms, ball joints, etc. do not show any issue, but there is some movement to my drag link. I tried swapping tires front to back, didn't make any real difference, so replacing the drag link is next. I just haven't gotten around to it since it's not a constant issue and there very little movement.

Tire balance is a likely cause, but you've already done that so I would look at the drag link.

Another thing to check is tire inflation pressure. Make sure they are all equal, and you may want to try raising or lowering pressures to see if that makes any difference. One of the well-respected local Jeep shop owners mentioned to me that he once had a Jeep with a similar problem and by slightly raising the pressures reduced the issue.

subscribed for same issue

Kota7x 03-27-2013 09:58 AM

Thanks for all the help guys. My dad is going to go to Currie Ent today and pick up all new tierod ends and draglink joints that need to be replaced. Im really glad I am getting this fixed so that I dont have to put up with it more. Ill post my results after I get them installed.

This is exactly what is happening. But for mine bumps can start the shimmy (it does go away after speeding up though). Im going to rule out tire pressure until I get my steering tight again. I run 28lbs of air in the tires.

I would love to do this and get rid of the terrible RE joints but I cant for awhile. :(

What am I missing?
2 different tire shops stated you have a bent rim and the shakes when away when you put your dads rims on your Jeep? Why not replace the wheel ?

Because none of the other 4 are bent and I don't want to buy a new rim. This rim has been on the back ever since I got the MTRs (tire shops have always put it on the back, I wish thy had put it on the spare) and I put it up front after a rotation (forgot it was back there). After, it really started shaking I moved that bent rim to the spare and put the good spare on the ground. My wobble got better and never went away. I thought the spare might have been out of balance so that is when I swapped rims and tires on both cars. Mine didnt shake on dads and his didnt shake on mine (like I said above though, it is a sporadic shake, it does it sometimes and other times it doesn't). I got back to the house and started messing around with other things under there: trying to tighten bolts, moving bars and control arms around trying to see anything out of the ordinary. I kept coming back to that drag link and sure enough the drag link moves up and down when it isnt supposed to. When it moves up and down I can watch the tire go back and forth just like the wobble. This explains why I can also feel the wobble directly in the steering. Im going to change the ends on the tie rods and drag link and see what happens.

Kota7x 03-27-2013 12:50 PM

Can anyone confirm that the drag link is supposed to move as much as it does in the video above?

Looks like the ends are worn out, there is metal contact where there should not be, should be grease cover and ends tight...probably good idea to replace that stuff.

No it's not supposed to move like that. My drag link system was worn similarly. I replaced the whole thing (i.e, tie rod, drag link and steering stabilizer) and it fixed the problem.

Kota7x 03-27-2013 03:01 PM

Thats what I thought, Dad went to Currie today and by what he has told me over texts they said it is supposed to move, but this seems more than just a little bit of movement. Ill keep you guys posted. I might just have to drive up to Currie tomorrow to show them the movement.

The bushing allows the end to move but not freely like you show in your video. If everything is torqued down to spec and you are able to move it freely with little effort, something is wrong.

Exactly what I was thinking. I know it isnt supposed to be tight but it doesnt take much force to move that drag link up and down. Im going to bet it is the ends that need to be replaced.

Kota7x 03-28-2013 04:51 PM

Update: went this morning to Currie to pick up new ends and a drag link. I havent even tightened the bolts on the drag links and it doesnt even move. I think I have found my problem.

Hopefully this corrects the issue. Just a reminder to grease your Currie ends. You can over-grease so be careful. Rotate/cycle the rod end when you are greasing so that it flows through. If you don't feel it taking don't try to force the grease in.

Just drove it and it feels pretty dam good. Going to drive it to dinner tonight and see if it does it.

We called Currie and they said that their ends come greased out of the box. Ill check them though.
