What is a rear axle assembly?
Table of Contents
A rear axle assembly is a very large and heavy piece of steel and iron that is used to propel the vehicle by converting rotational force into linear motion. The drive shaft sends rotational power from the engine and transmission to the rear axle assembly differential.
What is the assembly in axle?
Axle Assembly – This refers to the axle shafts that are found at the front of a FWD vehicle, and at the rear of an AWD car or SUV. They do not support any vehicle weight – they just transfer power from the engine to the wheel. CV Axle – CV stands for Constant Velocity.
What are the two types of rear axle assemblies?
Types of Rear Axle
- Semi-Floating Axle: This rear axle connects the wheel to the flange on the exterior of the axle shaft and holds it securely.
- Full-Floating Axle: True to its name, this axle type effectively floats in place and maintains its position, thanks to two bearings.
What are the components of the rear drive axles?

What is the rear assembly?
A rear axle assembly is a very large and heavy piece of steel and iron that is used to propel the vehicle by converting rotational force into linear motion. In most vehicles, the rear axle assembly is the second largest and heaviest component of the vehicle, second only to the engine block.
Where is an axle?
An axle or axletree is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle, with the wheels rotating around the axle. In the former case, bearings or bushings are provided at the mounting points where the axle is supported.
What are the different types of rear axle?
Depending upon the methods of supporting the rear axles and mounting the rear wheels, the three types of rear axles are as follows:
- Semi-floating axle.
- Full-floating axle.
- Three quarter floating axle.
Where are axles used?
All wheeled vehicles have axles. Axles are used for steering, driving, and braking, meaning they are important for basically every aspect of vehicle use. Essentially, the axles transfer power and torque from your engine to your wheels.
What is an axle made of?
Axles are typically made from SAE grade 41xx steel or SAE grade 10xx steel. SAE grade 41xx steel is commonly known as “chrome-molybdenum steel” (or “chrome-moly”) while SAE grade 10xx steel is known as “carbon steel”.
Where is the axle seal?
An axle shaft seal can be found in a few different places: On a vehicle with a semi-float live axle, the seal is at the outer end of the axle tube. On a truck or SUV with front CV axles, the axle seal is at the inboard end of the axle where it goes into the differential.
A typical rear axle assembly is shown in The rear axle assembly is used on rear-wheel drive Figure 16-1. vehicles. This assembly is the final leg of the drive train. It In a rear axle assembly, engine power enters the drive Bolt is often called the final drive or rear end.
What is the pinion on a rear axle called?
It In a rear axle assembly, engine power enters the drive Bolt is often called the final drive or rear end. The rear axle pinion gear from the drive shaft assembly and differential assembly is often mistakenly called the differential. The pinion yoke/flange.
How do you adjust the rear axle of a car?
This is generally done by using axle shims passes the vehicle weight through the axle shaft and out to the the vehicle weight from the rear axle housing to the wheel hub The axle retainer plate keeps the axle and bearing retained in or by turning an adjusting nut. Tapered roller bearings may wheel.
What are the forces on the rear axle?
Forces on rear axle Wt. of the body Driving trust Torque reaction Side thrust 4. Automakers have developed a number of common methods of locating a live axle First approach uses four trailing arms, two above the axle, two below it, angled inward so that they resist lateral motion of the axle.
