Death Wobble in STOCK Wrangler...?

Okay, so I go and get my tires balanced and when I get it back, it rides great until 55mph. At 55mph to 60mph, I get an oscillation that will erupt into full blown death wobble when I hit a bump.

Scary as chit. I had a similiar thing happen when I got my first balance job done at a different place. I took it back and they said that there wasn't anything wrong, so I drove on it for a month and it went away. Now its back in force and its been a month. Its not going away.

So what would cause the death wobble? My TJ is stock, no lift, stock tires on stock aluminum mags.

Thank!
Fritz

No experience with TJs so take this for what it's worth. [img]images/graemlins/tongue.gif[/img]

I'd be checking things like steering bushings and shocks. Worn out bushings in the wrong places can cause some scary stuff. When was the last time you had a thorough alignment job?

I don't have much faith in a Saginaw's ability to stay tight. It might well need to be adjusted. Have a buddy rock the steering wheel while you check every connection from column to wheels. Any slack will let a wobble start, and once it starts it gets worse.

The track bars like to wear out and cause all kinds of issues. I know i had some track bar issues and would have bad death wobble with the tj.

bad steering dampener, worn out u- joints up front (the ones on your front axle) or your sreering box. - just my 2 cents-

Re: Death Wobble in STOCK Wrangler...?

You got a bad tire balance. Vibration in the speed range you are talking about is almost always bad tire balance. You might try loosening all the lug nuts and retighten them to see if they got a wheel cocked by a few thousandths.

When did it start? Immediately after the balance or a few miles later? You could have thrown a wheel weight. If you have alloy wheels, don't let them use clip-on weights, mine won't hold them anyway.

Re: Death Wobble in STOCK Wrangler...?

I'll try loosening the lugs tonight.

It happened right after the balance job on the way home.

I should hope that with only 40,000 miles on the odo, it wouldn't have any worn out parts. I don't wheel this Jeep yet, so abuse isn't a concern.

I'll run through the whole thing tonight and if I don't see any change by Monday, I'll take it back and ask for the shop to rebalance.

What should they use instead of clip on wheel weights? Adhesive?

Thanks, Fritz

Mine was a bad newish tire and a loose shock.

[/ QUOTE ]Yep. Make sure they put them on the inside, not on the outer rim edge. They'll tell you that they won't hold, but they will. Take a spray bottle of wheel cleaner (I use Eagle 1) and clean where they are going to put the weight. I've had some that when they took them off, the weight came off and the adhesive strip stayed on the wheel.

Since you asked the question about what to use, I assume you have alloy wheels and they used clip on weights. I'd bet and give odds that you lost one on the way home. It could be that they just didn't balance them right to begin with though. If you stand there and watch them, make sure they recheck the balance after they install the weights as a double check.
