Exam 40: Drive Axles and Differentials

U-joints rotate at a constant velocity and are vibration free.

Axle shafts with CV joints at each end are found on the ______.

What is a slip yoke?

Which type of drive axle supports the weight of the vehicle?

The bearing cups of a conventional U-joint are retained by ______.

Constant velocity joints are used to transfer uniform torque at a constant speed, while operating through a wide range of angles.

Technician A says when the left-side axle shaft on an FWD vehicle is longer than the right side, torque steer is reduced. Technician B says the torsional damper on the axle shaft automatically balances the shaft. Who is correct?

The needle bearings in a conventional U-joint ride between the bearing cups and the ___________________ on the cross.

CV joints are typically used in front-wheel drive vehicles.

Technician A says side bearing preload limits the amount of lateral movement to the differential case in the axle housing. Technician B says adjusting backlash sets the pinion gear depth. Who is correct?

A FWD vehicle that makes a clunking noise when the automatic transmission is shifted into gear is being diagnosed. Technician A says the problem could be excessive play in an inner or outer CV joint. Technician B says the noise could be produced by excessive backlash in the differential gears and transmission. Who is correct?

Describe how to measure ring and pinion gearset backlash.

Ring and pinion gearset contact patterns are being discussed. Technician A says a gear tooth pattern can identify a backlash problem. Technician B says a gear tooth pattern can identify a problem with the pinion depth. Who is correct?

Front-engine RWD luxury-type vehicles often use a double U-joint arrangement called a ______.

An ___________________ is used to check the operating angle of the drive shaft.

Adjusting ___________________ sets the depth of the mesh between the ring and pinion gear teeth.

A ____________ axle does not drive a vehicle. It merely supports the vehicle load and provides a mounting place for the wheels.

Some FWD half-shaft axles are equipped with vibration damper weights.

Driveshafts are made of ______.

Some ring gear assemblies have an ____________ ring, used in antilock brake systems. This ring is normally pressed onto the ring gear hub and can be removed after the ring gear is removed.
