True or False question
6. Torque reaction is when the axle housing tries to rotate in a direction opposite to wheel rotation
☐ True or ☐ False
7. What is torque steer?
Torque steer is the influence from the engine torque which is not intentional. This is mainly in the front wheel of the
drive vehicles. This is caused by various number of things such as variance of traction between the two drive
wheels. This effect is more evident in the case where high torques are applied to the driving wheels. This is
because of the overall reduction ratio between the engine and the wheels along with the combination of high engine
torque. The most common cause of for having a torque steer is front wheel of the driving cars which is transversely
mounted on the engine.

D. All answers are correct.
10. What is a slip yoke?
Slip yoke is the component of a drive shaft. It is very important in assembling the drive shaft. This assembly allows

the drive shafts to flex and slip in their given application. It is an important component which allows the U- joints to
rotate in a proper manner along with the drive shaft. It transfers power from transfer case to the drive shaft while
sliding in and out of the transfer case. It is the part of drive shaft which connects the drive shafts to the output shaft
for the purpose of transmission.

☐ True or ☐ False
True or False question
17. The U-joint is basically a double-hinged joint consisting of two Y-shaped yokes, one on the driving or input
shaft and the other on the driven or output shaft, plus a cross-shaped unit called the cross.
☐ True or ☐ False
18. Name the three (3) common designs of U-joints:
1 Hooke - This is also known as joint which consists of two rods. These rods are connected by the four
pin attachment. The two rods are slender on the outer side while thicker on the inner side.
2 Ring and turnnion - This universal joint is designed consisting of the male and female rods which are
present on the ends of the center cross points. The center cross is a type of open circle which includes
four points which are coming out of the holes present on the male and female rods. In the center part of
the ring and trunnion of the U- joint a bushing and lock ring is present which helps in maintaining the
center cross between the two rods. This design of U- joint is mostly seen in the drive shaft of a vehicle.
3 Bendix- Weiss - This U- joint has a hollow center which includes some small metal balls. Two of the
rods are formed as a hook together present in the cross section while the metal balls are placed in the
corner of the socket. The smaller ball is present in center of the cross point and helps in stabilizing the
entire device at the time of rotations. This design is useful in carrying exact amount of torque and forms
equal balance and is therefore, applicable for heavy and complex vehicles.

AURLTQ012 Diagnose and repair light vehicle drive shafts
True or False question
21. U-joint operating angle is determined by taking the difference between the transmission installation angle and
the drive shaft installation angle.
☐ True or ☐ False
22. What does the term “constant velocity” mean?
The term constant velocity is related to the object moving in motion and having a constant speed. It helps in
depicting the direction where the object is moving.
Constant velocity in terms of drive shafts are a different type of drive shafts which will allow having a continual
rotational velocity from the variable angle without having any significant increase in the amount of friction.
The constant velocity are used to connect the transmission of the vehicle to the wheels. It is a part of drive shaft.
These joints are used in front wheel of the drive vehicle as well as in the rear and four wheel drive vehicle,
This term is associated with the joint because it has the ability to move the suspension of the vehicle in any
direction while making it move at constant velocity.
True or False question
23. In a two-piece driveshaft, when the yokes are in the same plane, the joints are said to be in phase.
☐ True or ☐ False
24. What is meant by U-joint phasing?
Phasing is the process which consists of aligning. This alignment is done between the yokes of universal joint
present on both the ends of the drive shaft in a parallel manner.
When these joints are not places in a proper phase, it will lead to operate at the variation in speeds throughout
every revolution. This causes second order vibrations.
These vibration results in increasing the wear and causing the damage to the assembly leading to failure in
application. Phasing ensures the correct alignment between the yokes present at each end of the drive shaft.

25. Examine the illustration below and note that the operating angle at the front of the drive shaft is offset by the
one at the rear of the drive shaft. Why?
The operating angle for universal joint angle ion each end of the drive shaft is supposed to be equal and within the
limits of one degree with each other.
This is important for having a vibration free performance of the shaft. Vibrations will lead to increase the wear and
tear of the machine which ultimately will lead to failure of the application.
Negative driveline angle means that the slope is pointing in the downward direction. The operating angle of the U-
joint is relation between two slopes such as transmission slope and also the tube slope.
26. Name the five [5] external components of the drive axle below.
1 Boots
2 Outboard CV joint

33. Identify three (3) symptoms of a failed U-joint.
Unusual sounds - It is the most commonly seen symptom which are notice when the U- joint failure. A sound of
clunk and ring is heard at the time when the vehicle is shifted from drive to reverse. This is caused by the joint
bearings having the worn thin and not proper lubrication. These sounds can be heard at low speeds and
replacements must be taken immediately.
Vibrations - This happens at middling speeds and is caused by the U- joint failure. This is because the driveshaft is
moving in side to side manner slightly with each rotation. These are higher frequency vibrations that will imbalance
the wheels which are accompanied by side to side movement while driving. It indicates the imminent failure of the
U- joints where immediate replacement is recommended.
Fluid leaks - The fluid from the transmission leaks from the side of couplings. This indicates that the joint is
separated from the transmission or even from the differential. This problem must be fixed with immediate concerns.
True or False question

spraying on chassis parts
It leads to contamination and
incompatible grease. It causes
vibrations and centrifugal forces.
Use of grease gun and couple of
aerosol can for the lubrication.
Clicking or popping noise heard
when turning curves and corners
It causes clicking ad popping sound
from the side of wheels which
indicates a broken C V joint.
Use of grease.
A clunk during accelerating,
decelerating, or putting an automatic
transaxle into drive
It is caused by the bad pinion
bearings and loose bearings in
preload.
