AN INTRODUCTION TO THE AUDIOLEARN MANUAL TRAIN DRIVE AND

AXLES TEST A3

This AudioLearn study guide that you are listening to has been developed in such a way that it provides you with all the requisite information needed to successfully sit for the Manual Train Drive and Axles test. And the structure used here consists of twelve important chapters which cover all the task specifications and task lists you are required to know.

The chapters in the AudioLearn study guide are also complemented with images or pictures which you can only view by referring to the PDF file attached to the audio book. It is important to note that each image will be referenced while you are listening to the guide and you are expected to view the image to better understand the AudioLearn guide. These images will also provide you with a great avenue to visualize everything you are expected to learn throughout your study of the Manual Train Drive and Axles test.

At the end of each of the twelve chapters in the AudioLearn study guide, the key information which you have listened to throughout the course of the chapter will also be outlined. These key takeaways will serve as reference points to help you easily recall all you have learnt from a chapter. Note that the Key takeaways are not the only mindrefreshing tools you have been provided with. This is due to the fact that at the end of each chapter, ten multiple choice questions written according to the question format of the Automotive Service excellence testing procedures will be asked. And the answers to these questions can be found in the accompanying AudioLearn PDF file.

Finally, at the end of the AudioLearn study guide, hundred questions that were generated from all the test specifications contained in the Manual Train Drive and Axles certification program will round-off the AudioLearn study guide. These questions will also closely follow the testing format of the Automotive Service Excellence certification program thereby providing you with adequate materials to prepare for the examination day. The answer to these questions and why they were chosen will also be included in the AudioLearn PDF study guide. Therefore, it is recommended that you first answer the

questions while timing yourself before proceeding to ascertain your performance using the provided answers.

MANUAL DRIVE TRAIN AND AXLES TEST A-THREE (A3)

The Manual Drive Train and Axles test was developed with the aim of testing your understanding of manual drive train components as well as how they operate in optimal conditions. The test was also developed to check your ability to diagnose the common and not so common problems that relate to modern drive trains and axles. The test will also take into consideration the different equipment and tools needed to diagnose issues with a manual drive train.

The task of servicing a manual drive train not functioning at its best is also covered in details in the third test under the Automobiles and Light Truck test series. Now, in order for a candidate such as you to be successful in taking the test, it is important that you have an understanding of the testing procedure used by the Automotive Service Excellence organization. This is due to the fact that having some understanding of the type of questions to expect will get you better prepared for taking the test. Therefore, the next paragraphs will introduce the question formats used by the Automotive Service Excellence program in conducting its series of tests.

Every certification test in the Automotive Service Excellence makes use of the same testing and question format. And the format the Automotive Service Excellence organization makes use of the multiple choice question formats. Multiple choice questions are those questions that are asked or stated and are accompanied by objective answer choices which you are expected to select the correct answer from. Therefore, the Automotive Service Excellence multiple choice question formats includes a question statement and four objective answers titled as A, B, C, and D.

LEAST-LIKELY QUESTION FORMAT

Finally, we have the LEAST likely format to explore. The Automotive Service Excellence organization makes use of LEAST likely questions as a counterbalance to the most likely question format. And with questions in this format, you are expected to choose the least likely cause of a specific problem from the answer options provided in the exam booklet. It is also worth noting that the task of identifying questions in this format has been simplified by the Automotive Service Excellence organization. This process is simplified due to the fact that the word ‘LEAST’ will be written in capital letters to highlight the fact that you are about to provide an answer to a LEAST-likely question. A good example of a LEAST likely question is the following:

A faulty vehicle is brought into the shop for repairs. What is the LEAST likely diagnostic procedure to start with?

a. Listening to the customer’s complaint

b. Checking the battery for damage

c. Uninstalling the crankshaft

d. Listening to the sounds coming from the vehicle.

The answer is C. Removing the engine and uninstalling the crankshaft or any other component is the LEAST likely first step to take when inspecting a car for damage. Here, you can see that LEAST likely questions are a bit easier than some of the other question formats and the word LEAST has been capitalized to help you know the type of question you are tackling.

UNDERSTANDING THE CONTENT STRUCTURE OF THE MANUAL DRIVE

TRAIN AND AXLES TEST

The Manual Drive Train and Axles test was developed with the aim of assessing your knowledge of diagnosing and repairing damages to an automatic transmission system.

• Driveshaft: the driveshaft also known as the propeller shaft is a mechanical component that transmits torque or rotational force from the engine to the drive train. A driveshaft is also a connecting device that connects other components of a drive train.

• Transaxle: A transaxle is a component that combines the functionality of other components such as the transmission, axle and differential into an integrated assembly.

• Gearbox: The Gearbox or transmission is a part of the transaxle and it consist of gears and gear trains which provide speed and torque conversions from a rotating power source to other components.

• Differential: A differential is basically a gear train that consists of three shafts. The differential functions in such a way that at any given time, the rotational speed of one of the three shafts can be equal to the average speed of the other shafts. The rotational speed can also be a fixed multiple of the average speed of

The rear-wheel drive train assembly is generally found in older cars and it has some advantages. The advantages include; superior breaking and it splits the job of steering and driving in the vehicle.

The rear-wheel drive train consists of the following:

• A driveshaft

• Differentials

• Transmission.

The Front-Wheel Drive train – most modern vehicles are powered by a front-wheel drive train arrangement. In this arrangement, torque is transferred to the front wheels to move the vehicle. To view the front-wheel drive train, refer to your AudioLearn Study guide PDF. The front-wheel assembly and its components are highlighted in figure
