Shakes 55-60mph

My 2004 Sport has been shaking around 55-60 mph when i got above 60 its fine and below 55 its fine. i can mostly feel it in the steering wheel. I installed a new steering stabilizer thinking that may help, no difference. Nothing feels loose in the steering so i don't think its tie-rod ends or the steering box. You guys have any ideas?

Tire balance? I had the same problem, only it was between 45-50 mph it would shake like no-body's business. Then i bought new tires, the installation guy told me the wheels were really messed up and needed a lot of weight. Now it rolls like a dream.

probably tire balance. check to make sure your track bar is tight though. Search "death wobble"

Check tire pressure weekly, balance and rotate religiously every 3K. GSA tires are prone to this issue. Mine always came back shaking when I reached 2500 miles after balancing.

There's something causing this across Jeep Wranglers -- just tooo many Jeepers experience this.

I've moved onto MT/Rs and have less of this issue, but very very slight shakes occur at 70mph. When I balance & rotate it will go away, only to return in about 3K.

I was having death wobble between 40-50mph -- until I got an alignment. Might want to look into that.

Good advice! Keep them rotated correctly. Make sure they are balanced 0 to 0. Meaning PERFECTLY BALANCED. Almost is not good enough. Tires sometimes sling weights off. Make sure your frame side track bar is tightened to 55ft pounds too. If that doesn't take care of the shimmy check your alignment specs and make sure it it between 1/8 to 1/16 toe in. Unless you have badly worn tires or have broken a band this should fix your shimmy. Good luck!

My 99 sahara would always do it whenever I'd breach 80mph or hirer. I always assumed it was a wind resistent thing.

Alignment doesn't cause shaking so I'm still thinking tires. Not all tire shops give a crap about getting tires balanced as perfectly as they need to be on a Wrangler. There have been some balancing jobs I've had done where it took three attempts to get it right so I had no more shimmy/vibration. That was with Discount Tires. The third time, they put it on a different balancing machine which I seem to recall it being called a "Ride Match" balancing machine which finally did the trick.

It's certainly not specific to any particular tire, it even happened to my MT/Rs. It's more just what can happen to any tire... wear unevenly through lack of rotation, weights getting knocked off & the tire wearing unevenly afterwards, road damage, trail damage, not rotating the tires as often as needed, etc.

I have 30" GS-As and had this same problem at ~55MPH. The whole front end shook horribly. This immediately followed me rotating my tires myself (and I obviously did not balance them). Since some tires that were on the rear moved to the front...BINGO, the problem surfaced. To the original poster...did this behavior occur right after a tire rotation? If so, I'd say that even though you got them "balanced", they didn't do a proper job. In my situation, a balance at Discount Tire immediately fixed the problem.

I had this for so long!! it happend to be my steering stabalizer. wasnt beefy enough once i replaced that the wobble went away. i used to have the wobble at 38-40 once i hit 41-41 it went away but then later it did it passed 60mph then i didnt drive untill i figured it out. took it in to get tires rotated and balanced also got an alignment but replacing the steering stabalizer fixed it 100%.

Unbalanced tire tread can do it too. I had to use my spare up front for a while (it had significantly less tread) and I'd get a rough shake in the 50's for a small stretch. Went away as soon as I got my new tire.

You have only masked your root problem by installing your steering stabilizer. As stated above, you need to have your wheels PERFECTLY balanced
