A vehicle with a lot of driveline vibration could have:
The two methods of drive line alignment are the parallel method and:
Before beginning any service or repair to a drive system:
The prime function of a drive line is to:
The main drawback of using a single cross universal joint applied to a driveshaft system is that:
Propeller shafts must be as short as possible and as large in diameter as possible to:
The two most significant factors in reducing driveline failure is:
To check a two-joint assembly for alignment, you must perform dial indicator tests at three different locations on:
What should a technician do when replacing a support bearing assembly?
A transfer case with an air actuator will not shift from the low gear ratio up to 1:1. The most likely first check is:
A truck has non-functional speedometer while the odometer operates correctly. The LEAST likely cause of the problem would be:
A technician finds dirt contamination when removing the 4X4 axle end-locking hub. What should the technician do?
The following are all acceptable steps to prepare the vehicle for a driveline angle measurement EXCEPT:
The recommended maximum run out on a driveshaft measured at the shaft centre is:
You can usually tell if a driveshaft is twisted by placing it on a level floor and making sure the flat surfaces on the yokes are both fully contacting the floor.
For good cancellation, working angles should be no more than ___________deg. difference on a drive shaft.
One of the first signs of drive line trouble is usually:
If a slip yoke is seized-up on interaxle driveshaft damage to the ________________________may occur.
A driver reports a relatively sudden onset of drive line noise. After a visual examination of the undercarriage, one of the first things to check would be:
Which of the following will not affect the drive shaft balance?
U-joints should be lubricated more frequently in excessive road spray conditions.
What is a good way to separate transmission noise from drive axle or wheel bearing noise?
A drivershaft without a slip yoke is usually found:
With parallel driveline alignment if the transmission is at -3 deg. the front differential should be at:
Before sliding a slip yoke off a stub shaft you should:
A constant velocity joint eliminates the:
Phasing of a drive shaft refers to:
During a routine drive axle oil change, a technician notices a few metal particles on the magnetic plug of the drive axle. What should the technician do first?
The purpose of a slip yoke and stub shaft (tube shaft) in a drive line is to:
When greasing a U-joint one should:
The most common cause of U-joint failure is:
When replacing driveshaft center support bearings, a technician should always:
What should a technician check for when replacing U-joints?
In a full time four wheel drive vehicle, or a tandem drive axle truck what is required in the transfer case/power divider?
A driveshaft should be able to:
The maximum recommended length for a drive shaft without a steady bearing is:
Brinelling of a U-joint is usually caused by:
A non-constant velocity driveshaft with a working angle speeds up and slows down twice per revolution.
Ideally the minimum U-joint working angle on heavy duty truck applications should be no more than:
Steady bearings are adjustable to correct drive line angles.
