Question 3

A _____ consists of two individual U-joints connected by a centering socket yoke and a center yoke that functions like a ball and socket.

Accepted Answer

A double Cardan Universal joint consists of two individual U-joints connected by a centering socket yoke and a center yoke that functions like a ball and socket. This design helps to reduce vibrations and improve torque transmission in certain applications, such as driveshafts for vehicles.

Question 4

Technician A says the mechanic's style U- joint bearing cups are held in place by metal lock rings. Technician B says some U- joints are held in place by injected nylon locks. Who is correct?

Accepted Answer

Both statements are correct. U-joint bearing cups can indeed be held in place by metal lock rings as mentioned by Technician A, and some U-joints use injected nylon locks to secure the bearing cups, as stated by Technician B.

Question 6

Technician A says the Universal joint has a center cross with machined arms. Technician B says it has bearing cups that contain a set of ball bearings. Who is correct?

Accepted Answer

Technician A is correct because a universal joint typically has a center cross with machined arms, which is a key component of its design. Technician B is incorrect because universal joints do not use ball bearings in their bearing cups; instead, they use needle bearings.
