The 'Frame Angle' refers to the angle of the engine mounts relative to the transmission.
The 'Frame Angle' refers to the angle between the front and rear wheels.
What does the 'Trans Angle' refer to in the context of driveline angularity?
The 'Trans Angle' refers to the angle of the transmission relative to level, as shown in the diagram.
The 'Trans Angle' refers to the angle of the driveshaft relative to the rear axle.
The 'Trans Angle' refers to the angle of the differential housing relative to the ground.

Constant velocity joints are not commonly found on heavy-duty truck systems. Is this statement True or False?
True
False
Constant velocity joints have 2 universal / Cardian joints in the same housing.
True
False
In constant velocity joints, what is true about the angle of each of the U-joints?
The angles are always different
The angle of each U-joint is equal
The angles change randomly
The angle of each U-joint is zero
Rzeppa joints create true constant velocity, as the operating angle of the joint always bisects the drive balls.
True
False
Which type of joint is capable of operating at much greater angles and higher speeds than traditional Cardan U-joints?
Rzeppa joint
Cardan U-joint
Ball bearing joint
Universal joint
What is the function of the bisecting plane in a Rzeppa joint?
The bisecting plane ensures that the operating angle of the joint always bisects the drive balls, creating true constant velocity.
It supports the outer race to prevent misalignment.
It acts as a lubricant channel for the drive balls.
It limits the maximum angle of articulation of the joint.
