What is Axle Wrap on a Truck?

What is Axle Wrap on a Truck?

Sometimes the axle wrap occurs in Toyota Tundra when you drag a heavyweight greater than the vehicle’s towing capacity. The axle is the part of every Truck that connects all wheels and runs it.

What is Axle Wrap on a Truck? The axle connects to the hub of the wheel and rotates it accordingly. Sometimes it wraps when you put the heavy load on Toyota Tundra, and the spring will become weak and soft. It will break during hard acceleration. You will hear the clunk and feel vibration when you start or stop the truck. You can fix it by adding a traction bar, greasing the axle, single bar setup, and double bar setup.

Sometimes the rear of the truck lifts when you stand on the brake pedal and slowly give the vehicle. The failure to keep the rear axle in place is called axle wrap.

The steering holds it, but it may lose the ability to control when you drive with fast speed for a long time.

How do I know if I have an axle wrap?

You can identify the wrapping of the axle by the following points and symptoms. 

Clunk sound

Sometimes it creates a clunk sound during braking and accelerating. Mainly the sounds occur when you start the Toyota Tundra and put your foot on the brake pads.

The sound will become violent when you drive with a wrapped axle for a long time. Sometimes there is no sound, and it silently damages the parts.

Slipping and grabbing of rear tires

Many people complain about the slipping rear tires, especially in the rainy season. The slipping and grabbing of the rear wheel also occur due to the wrapping of the axle.

The tires will lose traction with the roads when you drive the truck through the water.

Faulty Brakes

You cannot stop the vehicle properly when there is an issue with the axle. The steering system and brake pads link with the tires, so it will not stop the truck when wrapping the axle occurs.

Therefore, it is not safe for the driver during driving and especially when you park it at the side.


The axle will sag when you put heavy weight on the vehicle and touch the ground.

In addition, the bend in the parts will allow the wrapping, and it can also damage the undercarriage if you do not cover the lower part with a skid plate.

Broken Leaf spring

Leaf spring is the essential part of the heavy truck that minimizes vertical vibration. The Toyota Tundra has a heavyweight, and sometimes it damps the axle.

Leaf spring causes the shaft to fold when there is something wrong with it. The broken leaf spring will move the shaft between the frame and sag of the rear axle-spring loss ability to keep the rear axle centered.

Jumping of Truck

Many people do not prefer trucks for off-road and uneven surfaces. These are the best choice for racing and for smooth driving, but sometimes it jumps from the rear side and the risk of accidents increases. The truck will jump when you suddenly reverse it, and you will hear the sound.

Will bad shocks cause axle wrap in Toyota Tundra?

The bad shocks cause the axle wrapping because it is present in the bottom of the truck. So the company made the Toyota Tundra and added the superior quality axle to hold the heavyweight.

Sometimes the shock will cause wrapping of the shaft when you go through the bumps and heaps of dirt and stones. However, it has a shock absorber that will sense and protect the structure and body of the Tundra.

The vehicles can absorb minor shock, but sometimes the bad shock damage the vehicles. So the manufacturer does modifications and uses high-quality material for axle preparation.

What causes axle wrap in Toyota Tundra?

It happens due to the following reasons and creates disturbances during the long journey. 

High torque load

Every vehicle has its own specific towing capacity. For example, you can tow about 10100 pounds weight with the Toyota Tundra, but when you put heavy weight on the cargo bed or drag, it will cause load on torque.

It will burden the engine, and the torque produced will not divide equally on wheels.

However, the leaf spring becomes stiff due to many reasons such as dryness, installation of low-quality spring, lower flexibility, and high tension.

Hard acceleration

Axle wrap happens due to high torque loads and continuous fast speed. Many riders buy the Toyota Tacoma for racing in the desert because the big size wheel has firm traction with the ground; either it is mud, dirt, gravel, and sand.

When you start, stop, foot on and off the brake, driveline thumps, thuds, clunks, and bumps occur when you try for acceleration.

How do you stop an axle wrap?

You should try the following method to stop it when you hear an unusual sound, inability to cover a few miles and lift of rear side.

Add Traction bar

The most trending and famous method to reduce the wrapping of the axle is the installation of a traction bar. The length of the traction bar varies according to the length of the truck.

The traction bar is a solid bar that connects the frame and bears the heavyweight, and divides equally to all wheels. It also applies the torque on the wheel, and you go straight without slipping.


The dryness of the parts also produces unusual sounds when you start or stop the vehicles. Apply grease or oil for normal and continuous rotation.

It will rotate the axle in a suitable direction and provide smooth driving even in hilly areas and rough paths.

Reduce it with Stiffer Spring

You should replace the worn-out leaf spring with the new one when it causes the wrapping of the axle.

Sometimes the spring becomes soft and even break in harsh condition. Instead, use the flexible spring, which can compress or extend easily during driving.

Single bar setup

The single bar setup includes two ways such as fixed-length above the spring and variable-length above the spring.

The bar below the spring-fixed length

Fixed length single bar insertion is an option to stop the wrapping of the axle. Place the fixed-length bar above the spring, and it will handle the pinion angle at its place.

The articulation will stop, and the pinion angle will be steady, but the spring can go for more compression.

The first half of the spring shows higher compression in S shape, and sometimes it can increase the folding of the shaft.

Above the spring-variable length

You should insert the variable-length bar below the spring to reduce the wrapping of the axle.

The length of the bar changes several inches as the spring compressor relaxes. It will lower the chances of folding and provide an area for rotation and articulation.

The single bar below the spring

The insertion of a single bar below the spring will control the higher compression of springs and does not allow it to go S shape.

The professional fix the first half of the bar under the tension and straighten the spring when it tries to wrap the axle.

It is the best method for people who do not want more clearance from the ground but willing to minimize the chances of wrapping.

Double bar setup

The double bar includes the ladder and 4 link setups, which are more effective and durable than the single bar setup.

4 link setup

This setup is complicated but more reliable than any other method such as ladder bar. It controls the pinion angle and does not depend on the spring for articulation.

Instead, it forms a wishbone that maintains the distance between the wheels and allows them to rotate as the axle moves when torque applies.

Ladder bar

The ladder is triangle shape and consists of two rods that lift the axle.

The triangulation of the ladder bar does not depend on the spring. You should add this beneath the truck to prevent folding; otherwise, it will cost more when you change the damaged part.
