What is Jeep’s Death Wobble?

What Causes The Death Wobble?
As stated in the introductory section of this post, a Jeep death wobble is mainly common in customized Jeeps because of the alteration of the front suspension systems.
The main reason for Jeep death wobble is cheap aftermarket suspension systems that include a low control arm that is fixed and during installation of the front suspension system you have to re-use the upper control arm, this causes your transfer angle to limit adjustment of the suspension system.
The track bar can also cause your Jeep to have a death wobble, during the installation of the aftermarket suspension system some suspension kits don’t include a trackbar and for this reason, you will have to use your existing factory track bar impacting your suspension angles. A loose track bar bolt is also a common cause of Jeep’s death wobble and it’s the number one cause of Jeep death wobble reported by our readers.
Another cause of the death wobble is the toe angle of your front suspension system, this is when your Jeep wheels are pointing to the right or the left side at an asymmetric angle. To is one of the major alignment configuration parameters of your Jeep suspension.
Your Jeep’s caster angle is also a common cause of death wobble, installation of an aftermarket front suspension system is a candidate for throwing off your caster angle and this might result in the shaking of your steering and front suspension system when speeding.
Another cause of death wobble in Jeeps is loose or worn-out tie rod ends, this will cause your front suspension to shake and get worse when your turn around the corners, your steering will also tend to play a lot because the tie rods control the steering angles of your Jeep. The clamps connecting the inner and outer tie rods are used to adjust the steering angles of your Jeep. This is why after the installation of suspension systems you will need a wheel alignment to make sure the steering and suspension are back to their factory specifications.
Jeep Death Wobble Fix
Diagnosing and fixing a Jep death wobble is a puzzle since its mainly caused by loose or worn-out parts of your steering and front suspension system, there are several large and small parts of the front steering and suspension system and each one of them might be the cause of the death wobble you are experiencing, this means that there are a lot of parts you will need to check in the steering and front suspension system.
However, experts recommend first checking the bolt that holds the trackbar and axle together and tightening it as much as possible, this is the number one cause and causes almost 99% of death wobbles in Jeeps.
You should also check for toe angles, caster angles, and transfer angles. Other steering parts to inspect for looseness or inappropriate movement include the following:
- Rope Tie Ends (all four, plus the upper track bar end)
We recommend replacing your Jeep’s track bar & track bar ends if you have to turn your steering wheel further in order to turn your Jeep if your Jeep is hard to turn, and also if it has been previously pulled to one side before the heavy shaking (Jeep Death Wobble) began. You can also inspect your track bar for signs of wear and damage, or looseness which can happen slowly over time, some of the things to look for include cracks, bends, or worn-out ends.
Premium Heavy Duty Track Bar
We recommend heavy-duty track bars, over standard or adjustable track bars because they provide additional support to key areas where stress is likely to break the part apart, and also reduce the rolling resistance, and improve shock absorption s for better handling.
Durable Jeep Ball Joints
- Bolts for track bar mounting bracket
Recommended Track Bar Bolts & Mounting Brackets
- Steering Box Brace
Jeep CJ Power Steering Box Brace
- Steering Stabilizer (tighten up the entire steering system)
