In today’s modern vehicles especially Toyota 4Runner, there are upgraded features to make your driving smooth and risk-free. A locker is an essential mechanical component to gear up your driving performance. A better-locking diff will provide significant torque and power to keep the wheels rotating at the same speed. This allows the car to move even if one wheel suffers from traction and power.
However, if you have limited time but want the best budget-friendly differential, you can go with the ARB Air locker. The design, built quality, and performance are well appreciated. But if you don’t find it in your budget, go for details and make one yours.
What Is A Differential Locker And How Does It Work
As we’ll cover most of the matters related to differential lockers, first, we want to know what differential lockers are. Many newbie car owners don’t know the basic info about differential lockers. This is why they don’t know where to put it, how it works, and why it is crucial.
However, in the mechanical components category, the differential lockers play a significant role in making entire wheels spin at the same pace. It comes in handy, especially when you get stuck in rough terrain and suffer from better traction. Diff lockers then allow the car to run fine without involving all the wheels to the ground.
They are designed to lock up both axles and provide 100% torque with greater traction. These lockers are widely used in heavy-duty equipment, towing trucks, forklifts, and tractors to maintain or achieve the best traction possible in mud, sludge, and uneven surfaces.
Now let’s know how a differential locker works. During turning or cornering, the differential comes in handy. When turning or sticking the wheels on a curb or hole, this mechanical unit works like an open differential. It locks both side wheels together on an axle to maintain traveling at the same pace.
In the meantime, when it is locked, the wheels can rotate at the same speed and unbalance the torque. The locked diff insists wheels in order to rotate at an equal pace. Meanwhile, the wheels that are in the air don’t receive torque at all. But the opposite wheel receives 100% torque with traction and allows the vehicle to move. This is how a locking differential works.
Why Do You Need A Differential Locker For Your Toyota 4runner
Likewise, other vehicles need a differential, there is no exception for your Toyota 4Runner. First, enjoying off-roading without a differential locker is like a daydream. Unlike limited slip lockers, differential lockers send the required power to the wheels evenly. The following are some other reasons to choose a different locker for your Toyota Runner.
Proper power distribution
The power distribution of a diff lock is a masterclass, especially when it comes to the Toyota 4Runner. Toyota 4 Runner features an electronically regulated back differential that distributes equal power to both wheels. It ensures the wheels move perfectly while one wheel leaves the ground.
Better off-roading experience
The locking differential helps the car move gently by providing the optimal torque and power to the wheels accurately. When one wheel gets caught by the hole or loses its traction, this unit provides power to the opposite wheel. As a result, the other wheel rotates at the same speed and keeps the car moving. In addition, this locker locked the wheel to get you out of trouble. Ultimately, it delivers 100% torque with the best possible traction to regain speed and proper wheel rotation.
Better traction in Difficult Terrain
Another significant benefit of having a diff lock is better traction while accelerating. This is done without allowing the wheels to rotate differently. It then helps the single wheel to hop or drag during turns or take cornering even when speed is low. It can operate both open and locking differentials when required.
When you are at a sluggish speed and take turns, it works like an open unit. That is, it quickly switches between open and lock to ensure better engagement and power.
Super Easy Activation
The great thing about the diff lock is it has an activation button for easy and quick activation. In other words, you can easily activate it when required. You can easily activate the locking function. It is located in the dashboard. In addition, with this button, you can easily lock both wheels on a similar axle. So when a single wheel slips in mud or sand, it delivers equal power to both wheels to get out of the sticky surface.
How To Install A Differential Locker In Your Toyota 4runner
No matter which locking differential you are going to buy, you need to install it right. Without knowing the installation process, you can’t go with it. Here is a simple step-by-step guide to installing a differential locker in your Toyota 4runner.
Step 1: Make Sure you Have the right parts and tools
First, you need to check out the package that arrived to you and ensure there are all parts available. Also, make sure you have the following tools to get the project done hassle-free.
- Dial indicators;
- Bearing puller and adaptor;
- Dial calipers;
- Cross-pin bolt removal;
- B-14 multi-tool, 10mm, 12mm tool,14mm wrench;
- New gaskets and gasket maker;
- Gear oil;
- Race driver sets;
- Housing cutters;
- Exact bolt shim drivers;
- Calipers;
- Foot-pound torque wrenches;
- Brass Punches;
- Beam type or dial type inch-pound torque wrenches, etc.
Step 2: Remove the Driveshaft
The very next step is to remove the drive shaft. But before that, you need to lift the car with a jack and drain the differential fluid. Use a punch tool or hammer to punch and a 14mm wrench to remove the nuts. You can use a breaker bar as well. Then, disconnect the vacuum lines and electrical connector if needed.
Step 3: Remove the CV Axle
Now, get the CV axle off. To do this, take off the wheel first. Then, remove the cotter pin from the axle nut. Here you can spray some PB Blaster to make removal easier. Afterward, take off the axle nut. Here you can use an air gun with around a 32mm socket at the head. Remove the outer tie rod by hitting it with a hammer. This way, you can remove the CV joint.
Step 4: Remove the old differential
Once the CV joint, now, the existing differential. It’s pretty straightforward. You need to remove both wheels and get access to the axle. After removing the wheels successfully, unbolt the bots inside each axle. This way you can remove the existing differential.
Step 5: Install the New Diff
Here you go. You are in the final steps to complete the installation of a differential on your 4Runner. Now reassemble the parts the same way you disassembled them. Make sure you put the nuts and bolts in the same place they had before.
