Rears are the axles that are located on the back of a semi truck. These axles provide support for the entire weight of the truck and trailer, as well as any cargo that is loaded onto it. Without these axles, a semi truck would be unable to move or carry anything at all.
The rear axles of a semi truck come in various configurations and sizes, with four-, six-, and eight-axle trucks being the most common. The number of rear axles depends on the weight of the load being carried, as more axles are needed to support heavier loads. A four-axle truck can generally carry up to 80,000 lbs., while an eight-axle unit can hold up to 180,000 lbs. or more. In addition to carrying capacity, having more axles also helps improve traction on slippery surfaces by providing additional grip on the road.
Rear axles on a semi truck are typically mounted in one of two ways: single or tandem axle configurations. Single axle configurations feature one axle per side of the trailer, while tandem axle configurations feature two axles per side. Tandem axle setups offer increased load capacity and better stability than single axle setups, which is why they are preferred for heavier loads that require more support.
In addition to providing support for heavy loads, rear axles also play an important role in steering and braking systems on a semi truck. The drive wheels on a semi truck (usually located near the front) turn when steering inputs are made by turning the wheel left or right; this motion is then transmitted through the drive shaft and rear axles, causing them to turn in unison with the drive wheels and steering wheel inputs. In addition, when brakes are applied to slow or stop a semi truck, this motion is also transmitted through the rear axles so that all wheels receive equal braking force.
Conclusion:
Rears are an essential component of any semi truck setup as they provide support for heavy loads and help improve traction during operation. They come in various sizes and configurations depending on load capacity needs and can be mounted either in single or tandem axle setups for additional stability if needed. Additionally, rear axles play an important role in transmitting steering wheel inputs and braking force throughout the entire vehicle.

A drive line on a semi truck is an important component of the vehicle’s power train. It is the connection between the engine and the transmission, and it is responsible for transferring power from the engine to the axle and wheels. The drive line is composed of several components, including a driveshaft, universal joints, and yokes.
Rear-end collisions with semi-trucks can be dangerous and devastating. They can cause damage to your car, physical injury, and emotional trauma. It is important to know what you should do if you are rear-ended by a semi-truck.
A semi truck, also known as a tractor-trailer, is a large vehicle commonly used for commercial transportation of goods. It consists of a tractor unit, which is the cab of the vehicle, and one or more trailers that are connected to the tractor unit. Semi trucks are usually used to transport large volumes of goods over long distances.
The front part of a semi truck is known as the cab. The cab is an integral part of the vehicle and provides a safe, comfortable space for its driver while they are on the road. It also houses all of the controls, such as the steering wheel, brakes and accelerator, that are used to drive the vehicle.
Customizing a semi truck can be a daunting task, especially if you’re not familiar with the process.
