If you've never had this happen, don't laugh. It's called death wobble for a reason, you think you're going to die if it happens at highway speeds.

What would you do to stop the wobble in that situation?

Is there some sort of damper that can be added between the knuckle and the frame or steering rack to prevent that from ever happening? I thought I had read that this instability is inherent to having a solid front axle, so there must be some engineering solution to make it not a deathtrap.

Wait, is this something that just happens? Like, there's no component wear or failure here, it's just ---~~~===a jeep thing===~~~---?

It seems to happen when a variety of front-end parts are all pretty worn. I would imagine slapping lift kits and giant tires only aggravates the issue, too.

It's not present, then you add parts and suddenly it tries to kill you. Death wobble is fun. What's more fun is when everything is new and shiny, and it still happens.

I thought I had read that this instability is inherent to having a solid front axle, so there must be some engineering solution to make it not a deathtrap. Steering dampers only mask death wobble, they can't stop it. Death wobble is caused by something being worn out and allowing your front suspension to resonate. It's not just a jeep thing, but the combination of "old ratty jeep" and "lifted to make a trail rig" is the easiest way to get there. Just about any solid front axle setup can get it with the right worn out parts and a bit of a bump to start it. The best way to stop it is to brake vigorously, be careful to not cause a wreck.

It's normally wear and slop in the steering components, but lifting the suspension in a way that reduces the castor angle can make for some very odd behaviour too. Agree, if you've never driven with it at high speed, you don't know what you're missing out on...

A coworker's 19 year old son just crashed his Jeep Monday evening due to death wobble. Hit him when he went over a bump in a highway off ramp, he lost control and slammed into a tree at 40-some-odd MPH. Good times.

Seems like the solution to death wobble is once you bring the jeep to a halt, get rid of it immediately and buy something that can handle going over 40 mph without self destructing.

I thought I had read that this instability is inherent to having a solid front axle, so there must be some engineering solution to make it not a deathtrap. There is actually supposed to be a damper on there. There is one from the factory - just a shock absorber between the frame and drag link - but as noted, it helps but does not prevent if everything else is chooched. (Holy poo poo - Chrome spell-check recognizes "chooched".)

The factory damper is between the axle and the drag link. Edit: the dynamics are a bit strange on jeeps. Lifts gently caress up the geometry in several ways. Stomping the brakes causes the nose to dip and can change the toe enough to stop the resonance. Plus, it's way easier to cause a sharp acceleration with the brakes rather than the gas pedal in a jeep

In motorcycle world we get back on the throttle as hard as possible to get weight off the front end when it's slapping around. guess that's not a realistic option in a Jeep

You just pop a wheelie to get the front off the ground when it starts wobbling.

Collateral Damage posted:You just pop a wheelie to get the front off the ground when it starts wobbling. But it's a bump that triggers the death wobble. So, great, it goes away when your front end is in the air but as soon as gravity does its job you're right back in the same world of hurt.

Happened to my boss' brand new jeep with oversized tires right off the dealer lot. The thing had less than 1000 miles on it and he could reproduce the death wobble pretty regularly. Quite scary when it happens at 65mph right as you hit a joint of a bridge like this one

I've owned two 4x4 XJs with bigger (but not oversized) tires and never once got the death wobble, and I'm pretty sure they both need work on the front end. Simple cure is don't have a lifted Wrangler as your DD and don't drive it on the interstate if you don't have to.

I think my point is the mid/late 90's was not a good era for body styling. Though I suppose in 15 years everyone will be slobbering over those vintage molded curves like we all have a fetish for g-bodies now.

It's got a really good and low presence plus that 12-cyl. The 850s are already respected ala g-bodies too but pretty sure that's all in the ones with the 12.
