How To Use the Jeep Rubicon Axle Lock Button

Open Differential vs. Locked Differential: What Jeep Owners Need to Know

One of the biggest advantages of owning a Jeep—especially a Rubicon—is having the ability to lock your differentials for extra traction. But what does that really mean? And when should you use them?

In this post, I’ll explain the difference between open vs. locked differentials, share when to use lockers on the trail, and link to a video walkthrough of the Rubicon’s axle lock button.

(Educational info only; not mechanical advice—always consult your Jeep manual or a trusted mechanic.)

What is an Open Differential?

An  open differential is the standard system in most vehicles. It allows your wheels to spin at different speeds. For example:

• When turning, the outside wheel has to spin faster than the inside wheel.

• An open diff makes this possible by sending torque to the wheel with the least resistance.

The downside: on uneven terrain, power goes to the wheel with the least traction—often the one spinning in the air. That’s why open diffs can leave you stuck on rocks, mud, or snow.

---

What is a Locked Differential?

A Locking Differential  (lockers) forces both wheels on the same axle to rotate at the exact same speed, no matter what. This means:

• Power is applied evenly to both tires.

• If one tire is in the air, the other still has full traction.

• It’s much harder to get stuck on obstacles.

The trade-off: lockers reduce turning ability and can strain drivetrain parts if used on flat, high-traction surfaces (like pavement). That’s why you only use them off-road when traction is needed.

---

🛠 When to Use Axle Locks (Jeep Rubicon Example)

You’d want to engage lockers in situations such as:

• Climbing rocks or ledges 🪨

• Steep inclines or declines ⛰

• Muddy, rutted trails 🌧

• Snowy conditions ❄️

• Loose sand or gravel 🏜

On a Jeep Rubicon, you can press the Axle Lock button to activate front/rear lockers. Here’s my video tutorial:👉 How to Use the Rubicon's Axle Lock Button

 Pro Tip: Only engage lockers at low speeds in 4-Low. Avoid using them on hard-packed trails or pavement where wheels need to rotate at different speeds.

Open vs. Locked Differential (Quick Comparison)

Feature	Open Differential	Locked Differential
Wheel Speed	Different per wheel	Same on both wheels
Everyday Driving	Smooth, efficient	Not recommended
Off-Road Traction	Limited	Maximum
Best Use	Street, light trails	Rocks, mud, steep climbs

FAQ: Jeep Differentials

Q: Do I need lockers if I only do mild trails?
A: Probably not. Open diffs + good tires work fine for dirt roads, gravel, and mild trails. Lockers shine on technical terrain.

Q: Are lockers bad for my Jeep?
A: No, if used properly. Only use them in low-speed, off-road situations. Using lockers on pavement can damage drivetrain components.

Q: What’s the difference between a limited-slip differential and a locker?
A: Limited-slip diffs transfer some power to the wheel with traction, but not 100%. Lockers provide full 50/50 power split.

Q: Which Jeep models come with lockers?
A: Rubicon models come with electronic locking differentials from the factory. Other trims may need aftermarket lockers installed.

Understanding the difference between open vs. locked differentials can be the difference between getting stuck and conquering a trail.

For me, learning to use the Rubicon’s lockers was a game-changer. It gave me the confidence to tackle rocky climbs and muddy trails I never would’ve tried before.
