What Causes Death Wobble?


Are you the proud owner of a Jeep, truck, or 4X4? There are a lot of perks that come with owning such off-road vehicles, but there are also certain dangers that drivers should be aware of. 

One common and potentially quite dangerous issue that truck, Jeep, and 4X4 drivers should know about is the dreaded death wobble, which is as scary as it sounds.

Read on to find out what death wobble is, what causes it, and what you should do if you encounter this problem while driving. 

What Is Death Wobble? 

First and foremost, what is this death wobble that everyone’s talking about?

Basically, the death wobble is the term used for a sudden and violent vibration or shaking motion going through a large, off-road vehicle such as a truck or a jeep (see also ‘How To Take The Doors Off A Jeep‘). 

While vibrations and shaking can be caused by issues with alignment or even rocky terrain depending on your suspension, the death wobble is an entirely different thing.

Instead of being restricted to the steering wheel, it will go through the entire vehicle. Your steering wheel will also be jerking from side to side. 

As you can imagine if you haven’t already experienced death wobble for yourself, this is a pretty scary situation, and it means that controlling and steering your vehicle will be difficult. 

Is Death Wobble Dangerous?

Death wobble is called death wobble for a reason.

If you don’t react quickly and safely when it happens, your life and the lives of others could be in danger because your vehicle will be hard to control, meaning it could veer off the road or into another vehicle, person, or object. 

Therefore, death wobble isn’t something to take lightly – not that you’re likely to if it ever happens to you. 

What Factors Cause Death Wobble? 

Most of the time, death wobble is caused by improper suspension or components in the steering system that have become damaged or faulty. 

This is one reason why it’s so important to take care and follow instructions when installing new suspension parts in your Jeep or truck.

Modifying the suspension of your Jeep makes death wobble more likely, although it can also happen with stock Jeeps. 

One of the most common situations in which we see death wobble is when a vehicle with a modified or poorly installed suspension travels over a pothole or bump in the road at a speed exceeding 45 mph.

The combination of the speed, the weak suspension and the uneven terrain starts a violent shaking in the vehicle. 

Preventing Death Wobble 

Nobody wants death wobble to happen to their vehicle, so before we talk about what to do if it happens, we should first discuss what you can do to stop it happening in the first place. 

Preventing Death Wobble 

To make sure your vehicle doesn’t experience death wobble, you should make sure that your suspension system is always in good working order. 

That means regularly checking on the drag link, ball joints, and front track bar as well as other components related to the suspension system (see also ‘How Long Can You Drive With A Bad U Joint?‘).

A thorough inspection every few months is a good idea, and any noticeable damage, no matter how minor, should warrant an immediate replacement. 

You should also be aware of your tire pressure (see also ‘How To Check Tire Pressure Without Gauge‘) and wheel alignment.

Check the pressure of your tires on a regular basis and either inflate them or deflate them if it’s not in the optimal range. 

Even though misalignment of your wheels probably won’t be the main cause of death wobble if it happens, your truck will be more difficult to control in this situation if the wheels aren’t aligned correctly, so pay attention to this, too. 

How To Fix Death Wobble 

If you ever are unlucky enough to experience death wobble, the most important thing in the moment is not to panic.

You’ll need to focus and react quickly and calmly to get yourself out of this dangerous situation. 

Grip your steering wheel lightly and take your foot off the accelerator and lightly engage the brakes as you pull the car over so that it slows down and comes to a natural stop. 

Your first instinct may be to jerk the steering wheel and slam on the brakes, but this could make your vehicle flip due to the fact that it’s already shaking.

Gentle but firm movements are the key to getting yourself and your vehicle to safety. 

Once you have pulled over, you may wish to examine your vehicle yourself if you have mechanical expertise. Checking the suspension, tires, and wheels might lead you to the problem. 

However, if none of these seem to be the issue, or if you don’t have a lot of mechanical knowledge, it’s best to simply call a professional and schedule a check-up.

You’ll also need to call a car towing company to get your vehicle to the mechanic because it would be very unsafe to try and drive the vehicle yourself after experiencing death wobble. 

A mechanic will be able to do a thorough inspection of the ball joints (see also ‘What Is A CV Joint?‘), relocation brackets, and other components that would be too difficult (and even dangerous) for you to try and access and fix yourself without the right tools. 

Regardless of whether you think you’ve identified and can fix the problem, you should still get a professional opinion because some of the parts listed above might be damaged without your knowledge since you can’t access all of them without professional tools. 

Final Thoughts 

Death wobble is a very scary situation where a vehicle starts to shake and vibrate violently all over. This leads to a loss of control and can result in serious accidents. 

Death wobble is usually caused by a problem with the suspension, although it can also be triggered or made worse by high or low tire pressure and wheel misalignment. 

If you experience death wobble, you should calmly pull over and call both a towing company and a mechanic so that your vehicle can be moved and thoroughly inspected by a professional before any fixes are implemented.
