If you are battling the dreaded front-end shimmy, a Dynatrac Ball Joint Install is often considered the "Nuclear Option" for a reason. Unlike standard factory units, these ProSteer heavy-duty joints are built to handle the added leverage of larger tires and off-road abuse. The beauty of this system is that they are rebuildable on the vehicle. Once you press them in this time, you’ll never have to use a ball joint press on those knuckles again.

Why the Dynatrac Ball Joint Install is the Ultimate Jeep Death Wobble Fix
This cross-section of my factory 2022 Gladiator Rubicon joint reveals the "fatal flaw": a deformable plastic liner (polymer bushing). Under the stress of larger tires and off-road use, this plastic compresses, creating the microscopic "slop" that triggers a violent death wobble.
A Dynatrac Ball Joint Install replaces this weak point with a precision-machined, all-metal interface. By eliminating the plastic internals, you kill the root cause of steering play at the pivot point—making this the definitive "Nuclear Option" for a rock-solid front end.
Essential Tools: Why the Dynatrac Installation Kit is Mandatory
If you're renting a ball joint press kit from the local auto parts store, keep in mind that it's a "one-size-fits-many" kind of deal. This usually means it might not come with the right adapters to keep your fancy gear safe. If you're all set for a Dynatrac Ball Joint Install on your Jeep, it's worth spending a bit more to grab the dedicated install kit (DT JP44-1X3050-J). Trust me, it'll save you a headache down the road!
Check out the photo! These rings are designed to snugly fit right on the toughest part of the ball joint housing. This way, when the press does its thing, all that pressure hits the joint body directly, so you won't have to worry about squishing the rubber seals or messing up the delicate internals. Think of it as a little insurance to make sure your "Nuclear Option" upgrade goes in smoothly on the first try.
Safety First: Preparing Your Jeep for Service
A Jeep Gladiator can weigh nearly 6,000 lbs—having that fall on you will do more than just ruin your day. Back in the day, jack stands were often stamped sheet metal held by a single pin. For a job this heavy, I use modern versions featuring a double-locking ratchet mechanism and a secondary safety pin for total security.
When prepping for your Dynatrac Ball Joint Install, remember: the floor jack is for lifting, but the jack stands are for holding.
Pro Tip for Gear Lube: Since this job involves removing the axle shafts, elevate the side you are working on slightly higher than the rest of the rig. This simple tilt keeps the differential fluid (gear lube) inside the housing rather than draining out onto your garage floor when the shaft is pulled.
Muddy Ruttzz "Last Chance" Safety Tip: Old-school DIYers always slide the removed tires under the frame rails. If the unthinkable happens and a stand fails, those wheels might just provide enough clearance to keep you from being crushed. It’s a "last chance" safety factor that costs nothing but a few seconds of effort.
Step-by-Step: Removing the Factory Ball Joints and Unit Bearing
I'm going to give you a detailed breakdown of the procedure to change these ball joints out. This is going to be true (for the most part) for any ball joints. Check the manufacturers specs for details on whatever ball joints you are installing for torque and installation procedures. This is where my video can really help you out: Jeep Death Wobble Fix? Dynatrac Ball Joint Install Nuclear Option (Part 6)
Once The Jeep Is Secure The Teardown Begins
This is where most DIYers get nervous, but it’s just a matter of following the sequence.
Brakes Out of the Way: Remove the two 21mm bolts to pull the caliper. Pro Tip: Don't let the caliper hang by the rubber line! Use a zip tie or a heavy-duty hook to hang it from the frame.
The Unit Bearing: You’ll need a 13mm 12-point socket for the three bolts holding the unit bearing in. Once those are out, the axle assembly can slide out.
Protect the Seals: As you slide the axle out, support it with both hands. You don't want the splines dragging across the inner axle seals—if you nick those, you're looking at a full differential teardown to fix the leak.
Cleaning the Borehole and Prepping for the ProSteers
Before the new Dynatrac Ball Joint Install can happen, you have to prep the "borehole" in the C-gusset.
Inspect for Burrs: Use a fine file or sandpaper to clean up any nicks or rust. If the hole isn't smooth, the new joint won't press in straight.
Anti-Seize is Your Friend: Apply a thin coating of anti-seize to the new ball joint body. This prevents "galling" during the press and makes life easier if you ever (though unlikely with Dynatrac) have to service them again.
The Press: Installing the "Nuclear Option"
This is where that Dynatrac Installation Kit earns its keep.
Orientation Matters: Ensure your grease fittings are pointed toward the front of the axle.
The Sequence: Press the bottom joint in first. This allows you to use the threaded rod through the top borehole for better alignment.
The Snap Ring: The top ProSteer joint is finished off with a snap ring. Don't panic when you see there isn't one for the bottom—that's by design.
Critical Step: Reinstalling the Steering Knuckle and Torque Specs
With your heavy-duty Dynatrac Ball Joint Install now pressed into the axle Cs, it is time to slide the steering knuckle back into place.
It cannot be stated strongly enough: You must follow the manufacturer’s instructions for the specific ball joints you are installing. Torque values and procedures are engineered specifically for the materials and design of that joint. Do not guess and do not assume factory specs are the same as aftermarket HD specs.
For the Dynatrac ProSteer heavy-duty joints used in this build, we followed their precise sequence to ensure there is no binding and that the joints seat perfectly in the taper:
Component | Tool Size | Torque Spec | Notes |
Axle Nut (36mm) | 36mm Socket | 100 ft-lbs | Prevents unit bearing play |
Unit Bearing Bolts | 13mm (12-pt) | 75 ft-lbs | Use Blue Loctite |
Caliper Bracket | 21mm Socket | 125 ft-lbs | Mounting bracket to knuckle |
Caliper Slide Pins | 13mm Socket | 30 ft-lbs | Check for smooth sliding |
FAD Housing Bolts | 10mm Socket | 15 ft-lbs | Caution: Aluminum housing |
Wheel Lug Nuts | 22mm Socket | 130 ft-lbs | Torque in a star pattern |
As shown in the image, a quality, calibrated torque wrench is not optional for this step—it is mandatory. If you do not have one, most auto parts stores (where you rented the press) will have one you can borrow. Getting these specs right ensures the steering remains precise and prevents catastrophic hardware failure on the road or trail.
Reinstalling the Axle, U-Joints, and Unit Bearing
The reinstallation of the complete axle assembly is one of the final major hurdles of this Jeep Death Wobble fix. On the driver's side, this process is relatively straightforward. The entire unit—including the axle shaft, U-joint, and unit bearing hub—slides back in as a single component.
However, don't just shove it in. As I demonstrate on the workbench in the photo, taking five minutes to prep the components properly is "cheap insurance" for your axle:
Coat the Axle Splines: Use fresh gear lube (I'm using Amsoil Severe Gear here) to coat the axle splines before insertion. This lubrication helps the sharp edges of the splines pass smoothly through the inner axle seal inside the tube without nicking it.
Apply Anti-Seize: Paint a layer of anti-seize onto the main body of the unit bearing that contacts the steering knuckle. This prevents the steel bearing from rusting or seizing into the iron knuckle—a simple step your future self will thank you for when it comes time for maintenance.
Slide the Axle In (Gently): When you are ready to slide the assembly in, use two hands to fully support the weight. Do not let the splines drag. Your goal is to aim precisely for the center opening of the inner seal. Getting this technique right prevents the seal from tearing, which can lead to frustrating differential fluid (diff fluid) leaks later.
The Passenger Side Challenge: Mastering the FAD (Front Axle Disconnect)
While the driver’s side is straightforward, the passenger side of a late-model Jeep Gladiator or Wrangler JL has a "hidden" hurdle: the Front Axle Disconnect (FAD). Once you pull that passenger-side axle shaft for your Dynatrac Ball Joint Install, there is a high probability that the internal shift collar will slide out of place.
If you try to force the axle back in while that collar is misaligned, you will hit a "wall," and you risk tearing the expensive inner axle seal. To do this right, you have to open the FAD housing and manually reset the system.
The FAD Reset Procedure:
Access the Housing: Remove the four 10mm bolts holding the FAD skid plate and disconnect the electrical connector from the FAD motor.
Remove the Motor: Pull the four bolts holding the motor to the axle. Warning: Have a drain pan ready, as some gear lube will leak out here.
Reset the Collar: As shown in my photo, you need to manually place the shift collar back onto the inner axle shaft. This ensures the splines are perfectly aligned to receive the outer axle shaft.
Install the Outer Axle: Carefully slide your prepped outer axle into the tube, aiming for the center of the shift collar. Once it seats, you'll know it's locked in correctly.
Reassemble the Actuator: Line up the shift fork tines into the groove of the collar. Tighten the housing bolts in a crisscross pattern to 15 ft-lbs. This housing is aluminum, so precision is key to avoid stripping threads.

Conclusion: Is the Death Wobble Dead?
The Dynatrac Ball Joint Install is a massive piece of the puzzle, but it's called a "series" for a reason. By swapping out those plastic-lined factory joints for rebuildable, all-metal ProSteers, we’ve eliminated the primary source of "slop" in the steering axis.
We are one step closer to a rock-solid ride. In Part 7, we're staying in the front end to tackle a clicking U-joint that I discovered during this install—another "while you're in there" moment that every Jeep owner knows too well.
