I have a 1999 Jeep Wrangler (4 cyl) that has been infected by the infamous "Death Wobble". If this term is too slang then here is an article that can explain it better than I could hope to. I would like to fix this myself but I know very little about vehicles so I think I'm going to quickly get in over my head. Armed with my Hayne's Manual, Google, and a local You-Fix-It garage I hope I can make due.

The biggest problem I face is that this can be caused by a number factors and if I hope to do this myself I'll need to narrow it down to something specific.

  • Is it possible to determine the specific cause by behavior alone?
    • The problem started a few years ago and disappeared for a few months after I got all new tires and an alignment. I don't know why it came back though, I don't off-road.
    • It will usually start between 45-60MPH but will always stop if I change speed to >35 or <70. Most people with this problem report that it's anything over a certain speed.
  • Am I fool for attempting this alone with my current skill-set?
  • In the meantime, I can't always change my speed to stop the wobble and have to drive through it for a minute or two. I can control the vehicle fine so I am in no danger of wrecking, but am I causing excess damage to my Jeep by doing so?

Talking a look at the article some of the items you can check yourself, for example the ball joints. Other balancing and alignment actions require special equipment. I would suggesting taking that list and checking everything you are able to on your own first. Your Hayne's Manual should walk you through steps to check the suspension parts.

I own a 1987 Land Cruiser, the death wobble on these machine can come from a bad aligment, tie-rod ends that need replacement or the steering stabilizer. Basically something is now worn-out and loose.

But be aware, changing the stabilizer may just mask any underlying issue, so check everything else before replacing the stabilizer.

Found a recent Land Cruiser thread talking about this: forum.ih8mud.com/60-series-wagons/… –  Gabriel Mongeon Jul 5 '11 at 20:20
