Jeep shakes @ 55mph

This has been going on for some time but basically my Jeep ends up shaking violently once I reach 53-55mph. Anything after or before than, it's perfectly normal.

It's definitely coming from the front suspension.

Any explanations or help would be REALLY appreciated.

I'd definitely like to fix it myself rather than bring it to a mechanic.

Lose a wheel weight? Happened to me.

First thing to check is your tires

Ahh I didn't want to hear those words haha

I just went out and checked to make sure the track bolts or the control arms weren't lose and everything looks to be really tight.

How ever I did notice, but I don't think its the cause, the linage between the Pitman Arm and the Drag link looked a little funny. Correct me if I'm wrong but I noticed that the Pitman Arm would rise and set slightly from the drag link as I turned the steering wheel.

Thanks!!

I found about a month after I bought mine, that the pitman arm bolt was loose. I don't think this was the case when I got it. It did have a drop pitman arm when I got it, so I'm assuming it wasn't torqued to spec.

I put a stock arm on, and I still check that bolt every week. Not something I want to be without at speed. I think it's a 34 mm nut. I'd check that if it looks like the arm is moving up and down when steering.

My death wobble was cured by balancing my tires.

Had similar problem. Proper tire balance fixed it. Have that done before you start replacing parts.

Don't know if it applies to yours but if it's an auto you could be getting a torque convertor shudder. Ours did it more at 35 or so as it's mostly in town driving, but I could get it to do it on the highway too. Romp on the gas to get up to speed, and then back off to hold speed, and the TCC would go to lock up and shudder like nobody's business.

Felt like the whole front of the jeep was coming apart, yet not a wiggle in the steering wheel.

Read up and found it's a common problem with Chrysler trannys. And found an additive to add to the fluid to cure it. Works like a charm now. Otherwise Mopar's fix is replace the torque convertor, which in a lot of cases doesn't fix the problem.

I ended up going to my mechanic and he said the tires probably need to be balanced My friend who has a lifted XJ and the same problem, balanced his tires but the shaking continues.

I guess I'll do a little more research until next week when I can run it over to my mechanic.

Thanks everyone for all your help and suggestions!!

Your jeep looks stock, if that is it in your profile. Go have your tires balanced. Also how worn are your tires? You do not have DW.

It is stock and the tires are in really good shape. It's an 04 and there are only about 30,000 miles on it.

Do you really think its just the balance of the tires?

Yes I do. Mine did the same thing before I lifted it. My tires were also a worn to the point that I had about 10 to 15 K miles before needing new ones. Mine would do it around 47 to 52 or so mph.

Thanks Melissa, I really appreciate your insight! Did you have a mechanic balance it or did you do it yourself?

I'd do it myself but I'm not sure how heavy of weights to put on and all that stuff. I understand how to do it but I'm not a genius at it haha

Curky,looks like someone did the photo in PAINT. Easy to do.
Copy the photo, open with PAINT, and have at it. Fun program.

WOW - I have a 2004 Jeep Wrangler Columbia edition with exactly the same 55 mph "death wobble" with 46000 miles on the original Wrangler goodyear tires - last weekend had all 4 tires replaced, new alignment (the right passenger front was way off) and the wobble is GONE--for now!!! But other posters have commented that the new tires, rebalanced new alignment only is a temp fix that makes it SEEM like the wobble is gone, when actually there is something more sinister with a tracking bar -- but the mechanic assures me its all ok.. I think the whole thing is weird because its like at exactly 55 mph - when you slow down it goes away when you go FASTER than 55mph to 60 mph it also goes away and only returns if you travel at exactly 55mph. I do not understand why going faster would make the wobble stop, but it did. Now with the new tires, it is wonderfully refreshing to travel at 55 mph with no vibrating at all..Thanks to all you jeep peeps out there -- you are the best!!

Trust me if you ever have DW you will know it. It will not go away until you slow down, and you will need to clean the inside of your jeep.

if your tires are cupped then consider investing in new ones. balance them and add weight to any if needed. if your old tires are fine then balance them and put best two in front.

Bwahaha! I agree, def not DW. If anyone was to ever experience DW they would never get it confused with anything else. Its scary as hell...

Get your tires checked because it sounds like an unbalanced tires or maybe a shifted belt..

Mine did this too, right after having the tires balanced and rotated. The shop told me the tires were wearing unevenly and they balanced the best they could. On the way home, started shaking really bad. I looked at the weights on the front tires, and there's quite a bit on them. I'm going to get new tires and an alignment Monday. I'm hoping this fixes the shake. I miss driving it. Been about 3 weeks, however there was some vaca. in there where I couldn't drive it anyway.

Look up "resonance".

Mine has a shimmy between 50 and 55 like many others have posted. It has gotten worse in the 15,000 miles I've owned it and if my ears don't deceive me, my tires have gotten louder too (stock Goodyears). May be time for a forced upgrade (tires have plenty of tread, I just hate them ).

when mine did that a good spin balance did the trick. made sure i told him the problem so maybe he'd take a little extra time and do a good job-musta helped-shake gone
