Ok, so i had the wobble today after hitting a small bump in road @ 40mph. From what I've quickly looked up, it's probably a loose front track bar? Can i *hand* tighten that up myself or should i take it to the dealer? I'd hate to have them do it because you all know what that's like, but i guess it might be worth having a *front* wheel alignment done? So i was thinking about hand tightening up the front track bar and then taking it in for the alignment?

How do i tighten up the front track bar?

Do i need to look at anything else?

Thanks guys, appreciate any input.

Go through this link it tells you what to do, tightening is very easy requires a torque wrench.

Would recommend changing out the 14mm bolts and nuts Jeep uses with some 9/16"x3" grade 8 bolts to avoid wallowing of the mount holes and get some locking nuts or some Stover top locking nuts

All you need is a torque wrench and torque the trackbar down to 125ft lbs
As for an aligment, you can do it yourself rather than paying the dealer for it

Thanks guys, reading through all that now. Looks awesome and pretty easy stuff. Sweet!

So basically i'm going to change out the nuts and bolts on the track bar, torque to 125lbs and pray that's enough.

I bought the nuts and bolts and picked up a torque wrench on amazon which had a bunch of good reviews for $57.

Will update thread as i get this done hopefully next week, using wife's car in the mean time.

Neighbor has 4 door version and i'm alerting him to this problem.

Wish i'd done this before i had the death wobble. It lasted about 5 seconds and has only happened this one time.

If it keeps up i guess it goes to the dealership as a last resort.

There are other issues it could be just most likely is the trackbar, its not a bad thing to have a torque wrench or to change out those bolts anyway so you wont be hurting yourself for doing this.

There are other possible culprits but most likely I would say this. Did you have to pull over to stop the shaking? or slow down considerably?

I had to slow down considerably. Thanks for your interest. Really appreciate any thoughts about this problem. Just been using as a DD. There is this big sink hole at the end of our road that i like to ride through, funny as that sounds, wondering if that has slowly jolted things up a bit. And last year did a fair amount of riding around in the snow when it was deep to clear a path for the neighborhood but that's about it. Rotated the tires myself but never had a re-balance or alignment done and its up to 20K total mileage now.

I just did the same thing, changing out the 14 mm bolts on my 08. I took a good long ride and did not have any issues, hopefully it solves the wobble problem. I had no idea about this problem and how to address it until I saw it on this forum. Great cite! Good luck.

How easy was it? Just use a wrench to hold the nut and turn the bolt up to the 125lbs? Have to wait till i get time to do it. Did you take one side out first and then put the new bolt in and then do the other side, etc? Thanks for the encouragement. Kinda thinking its not going to be as easy as it looks. Also did you get the locking washers for the nut side, coz i forgot to get those but the nut locks as you thread it all the way in, also the thread isn't fine either and the thread doesn't run the whole length but i thought that might even be better. Did the stock ones seem loose before you swapped them out? I picked up the nuts and bolts from the local "do it best". Anyway, hope it fixes your wobble problem.

The frame side is easy enough, just a wrench to hold the nut and torque the bolt down to 125ft/lbs. The axle side is a bit tougher. You may have to remove the steering stabilizer (this is easy as anything as its just two bolts. The reason the axle side is more tough, is you will see that Jeep has welded on flags to the nuts, if you have a welder or could find a welder to weld some flags to match the Jeep ones on the new grade 8 stover nuts, then you would have a much easier time, otherwise it just will take some time as the space for the nut does not allow for a wrench to get in there. You will have to tighten by hand at first then tighten with a torque wrench after its down most of the way. If you have issues with the stover nut on the axle side, you can always swap it out for a regular grade 8 nut and locking washer, this is what I did, but requires re-torquing (I do it when I change my oil). I have had zero issues with it so up to you and what you find easiest. Im sure others will say they had no issues withe stover nuts at all, it is the recommended way to go.
