i guess i lucked out in my 2000 XJ (4.0/4x4)--i have 12-year-old tires on it with great tread because i hardly ever drive it. but the front ones were apparently f'ed and caused a serious wobble between about 30 and 60mph.

I rotated front to back and voila! (or "wala"--see OT thread from a few weeks ago). sounds like most death wobbles are more serious though.

my current issue is a vibration when idling/going slowly. replaced the usual sensor suspects. trying spark plugs next.

Had it in my XJ. Was a tire that caused the problem. It was bad from the get go. No matter how many wheel weights were added, it would throw them off in a short time. The dealer made the tire good and all well after that unless I get a shite load of mud stuck on the inside of a tire. That happens all the time.

The root problem is not the mud or the tire. It is the suspension/steering's inability to control that motion that starts the actual death wobble. I can drive with an egg in my tire with nothing but a vibration, but add in worn suspension/steering components and bad angles, and that becomes a problem

It's not just a vibration. It'll shake the steering wheel out of your hands and the pucker factor goes to 11 the first time it happens

I watched a YouTube vid of an F250 with death wobble, scary.

Bent wheels and tires way out of balance can cause the suspension deterioration and cause the initial start of the DW when driving.

OP, as stated by others, the bad parts can be several different areas on your front suspension, even the bolts/bolt holes. You really have to look at every component.

Mine did it a few times, I just took it in and had the tire rotated and re-balanced. Seems to fix it for a year or so each time.

I bet I had 10 pounds of lead on my tires by the time they wore out.

I'll just say it was not fun or funny. Shook bad enough for change to fly out of my cup holders, and they were as tall as half a 44oz fountain drink. I suspect a lot of guys here are talking about something much less. Braking made it worse. Coasting just prolonged it. Flooring it was the only way to stop it, and even then, going 100 with a tiny amount of death wobble isn't fun.

Part of it was due to ford's bad design, but most of it was because of worn parts

This is EXACTLY how mine was. I had to pull over on the interstate shoulder multiple times and really just collect my thoughts.

It was worse than this. Pretty freaky. I look back and think a lot of serious situations are funny. This is not one of those times

Check out the video I posted on the first page. I'd say that was mild.

It would've been neat to see the tires when it was going on, but I think a go pro would've fallen off

It got to be pretty ridiculous, and at the time I was commuting daily from Baton Rouge to Hammond for school.

I've always wanted a Jeep, but read this board for a few days will change your mind quickly.

Just watched the Jeep Death Wobble on youtube.

Thanks for all the input, guys.

I watched the videos; it's definitely the death wobble.

The term/description "death wobble" is absolutely perfect and kinda funny. The experience, however, is not.

It can be fairly easy to predict. it usually happens around the same speed and or scenario for you particular vehicle. Until you get it fixed just keep an eye out for how to get past it or prevent it while driving.

For instance, my old jeep prior to fixing the issue, DW happened in the 35-40 mph range, when hovering at that speed or slowly accelerating through it. So I either didnt drive in that range or sped through it.

Why? Go read any forum for any make of vehicle and you will very quickly learn not to ever buy that said vehicle. They all have issues of various sorts. The death wobble is a common issue on any vehicle with a solid front axle. Jeeps are just more popular and are often modified to the point that it accelerates the issue.
