Little wobble problem!!!

Hey everyone!!
I have a little bit of a wobble issue.. When ever I hit a fairly good sized bump or pothole my steering wheel shakes a little like the front wheels are trying to get back on track.. What would this be? The only thing I could think of was to check the alignment b/c it slightly pulls to the left anyways so I am in need of an alignment already just to be right on track.. Or ball joints but I haven't had it that long and my mechanic went over it top to bottom before I got it and everything checked out fine... Is there anything else it could be?

Thanks!

Do you have a lift and tires or are you stock?

It's called Death Wobble or DW. Search the forum as this is a huge topic. Many, many posts on DW.

Lifted Jeeps with 35s wear out the ball joints, track bar bushings, and control arm bushings faster than stock. When each is a little worn, the combined effect is overall looseness in a system that needs to be tight to function properly.

Repair or replace those items first. Then add geometry correction brackets, probably a new steering stabilizer, and you will be ready to roll smoothly again.

Eh, it sounds more like bump steer to me. If it was DW, then it wouldn't be a little bit of shaking. There's a reason it's called Death Wobble. It feels like the whole thing is gonna fall apart.

I'd say, little wobble may evolve into death wobble eventually. There is a difference in bump steer and floppiness after going through a bump. Bump steer is kind-of normal and usually at the moment the bump or any irregularity is hit as the trackbar and a drag link move along their planes. But, I've also experienced that "little" wobble in which after going over the bump the steering is still "wobbling" (leftright) not hard, but slightly, for like a second and a half. It's a different feeling to that of bump steer. Though I no longer have it as I've upgrade most of my front end as per the regular wallet-killing cycle.

Do the whole planman death wobble diagnosis.

Thanks everyone! Yea I know it's not DW because my buddy has a crew cab long bed duramax on 40's that has that between 45-55. But like GSN said it's only like for a second an very small left to right after going over a bump. But I will definatly start looking into the front end. First things first an alignment just because I can do that for a small amount of $20! WINNING!

True, could be bump steer. Or (from the sound of Jsouth90's description) a little bit of both. Full blown Death Wobble is usually preceded by minor wobble. Bump Steer is also very common with lifted Jeeps (many forum threads focused on solutions). Bump steer followed by a short period of "wobbling" and or vibration, will definitely wear out everything and eventually lead to true DW issues.

I recommend Jsouth90 try your best to fix whatever the issue is asap, before it gets worse.

With a 3" lift, I added correction brackets and eliminated bump steer altogether. Pretty cheap fix.

A simple way to recognize DW is the wobbling is violent, usually (not always) triggered by a disturbance above 40 MPH and almost always requires coming to a complete stop to eliminate. Everything is else is just considered a simple wobble or shimmy but as stated a wobble can lead to DW over time because they are both caused by big wheels (often out of balance) and a loose or faulty joint.

Always start by checking your tire pressure and balance (preferably dynamic balance) to eliminate/reduce the trigger and then methodically search for the root cause.

I bought and installed the AEV brackets before I learned of the Rancho brackets. Would have went for the Rancho brackets if I had a do over because they appear way more beefy.

I had this same issue at low speeds, between 25 and 40 mph. Turned out my steering stabilizer was blown out. Swapped it out with a $35 RE stabilizer and problem was gone. Took it to the shop to check out everything else just incase and everything was fine.

Just me experience with a similar problem.

This sounds like tires out of balance. Not a terrible problem and easy to fix. If it continues or gets worse and is not fixed, it could contribute to wear on the very parts which need to stay rigid.

A few simple checks that you can do with yourself and another person:

Jack up one side (at the axle), enough to get the tire off the ground. have person #2 wiggle the steering wheel while you're under it. look for play in the drag link and tie rod. have #2 try to turn the wheel (vehicle off) and look for excessive play in the same areas. also look at the panhard bar at the axle and frame for the same play.. all play should be very minimal. While this wheel is off the ground, grab the top and bottom of the wheel and do the same for the ball joints. this will require a little bit of rear end muscle. do the same for both sides.

It's a start, and easy to do.

The easiest way to properly diagnose proper Death Wobble is by checking your seat afterwards. If its clean, chances are it was not a death wobble.

Other common symptoms include but are not limited to,

Having to pry your fingers off the steering wheel afterwards.
Fear of freeways.
Empty wallet.
Learning much more about JK suspension that ever thought possible.
Sudden urges to pray to god.
Reevaluating your decision to buy a JK to begin with.

And anyone who has been through it will say the above is a mild evaluation!

This is accurate. September of last year, I was barely changing my oil. Since DW, a couple times I've caught myself explaining suspension geometry to professional mechanics. Had to burn that seat.
