Help!

Doing about 35-40 mph, I drove over a rough patch on the road and experienced terrible head shake/front end wobbling. I had to pull over to in order to regain control. Is this normal for a JK? Anyone have the same thing happen? Thanks.

It's "death wobble" have a wheel alignment & balance to start with also check underneath for anything loose. The trackbar may need new bushings or adjustment, I personally just had a gusset welded into my trackbar as it has quiet a large curve & was flexing. I didn't have a lot of wobble but it was not something I was comfortable with. If none of those things help, check ball joints as well.If you happen to have installed a lift then you need to have an alignment as soon as you do the lift. If it is new, take it straight back to the dealer & make them fix it. If not then it can be somewhat of a elimination proccess for you but it is fixable. Let us know how you go with it, good luck

Hah- that kind of behavior isn't normal in any vehicle, dude! If it were, who the HELL would buy it?!
Anyway, it sounds like, as JCF said, it may be death wobble. Bring it back to the dealership and have them check it out- Mark W.

could you post a pic of the weld that you did because I have heard of some weak spots with the JK suspension and when I do my lift I am going to add gussets where needed and finish out the factory welds, thanks

Sure, happy to. As you can see the bar has a large bend in it allowing it to flex. No problems now since the gusset

I had that exact same thing happen on my last 2 Cherokees. Driving down the road hit a pot hole a certain way and the steering wheel shakes like I have never felt one shake before. I just got a brand new Unlimited X was driving this weekend, hit a pot hole (not on purpose) and the wheel starts doing th exact same boogie shake on me. Honestly I just figured that's how jeeps are. You almost have to come to a complete stop to make it stop. I had my Cherokees checked out and they could never find anything wrong that would make it do it.

I had suggested that I just get a heavy duty track bar but the mechanic said it is fine that there is nothing wrong with it & the gusset was all it needed. Tried & true so I am a happy camper. He will be getting my business

Did you do the work yourself? What thinkness steel did use, it looks like 1/8" plate steel. I have a MIG welder and I can do this type of work but I would appreciate any details you may give me, thanks.

No sorry don't have the guage of steel, just happy to have someone else do it for me.I tried welding once when I owned a manufacturing business, was definately not something I was good at, so stuck to spray painting & office work
