Exam 40: Drive Axles and Differentials

A vehicle with a leaking extension housing seal is being diagnosed. Technician A says check for nicks and burrs on the driveshaft yoke. Technician B says a worn extension housing bushing could have caused the seal to fail. Who is correct?

A car has a cyclic vibration that comes and goes between 45 and 60 mph (72 to 97 kph). Technician A says the problem may be caused by an out-of-balance tire and wheel. Technician B says the Rzeppa CV joint may be bad. Who is correct?

C-shaped washers (C-locks)are used to retain the axle shaft used with _____ bearings.

The torsional damper that is sometimes attached to an axle shaft serves to balance the shaft.

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

What are the first two symptoms noticed when a differential or drive axle shaft problem occurs?

If a drive axle shows signs of rubbing against the chassis, the vehicle should be checked for ______.

Name the three ways in which CV joints can be classified.

Describe the action of differential side gears when the vehicle is cornering.

Which type of joint is NOT a constant velocity type joint?

Full floating axle shafts are found on ______.

A(n)____________________ CV joint is capable of providing an in-and-out movement to allow for changes in the suspension.

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?

Technician A says the differential allows torque to be transmitted to the driving axles at different speeds when the vehicle is turning a corner. Technician B says the gear ratio of the drive axle's ring and pinion gears provide a gear reduction and torque multiplication. Who is correct ?

Which type of CV joint has a flat design?

A collapsible pinion spacer is used to set the ______.

A humming or growling noise in the front of the vehicle that changes with road speed could be caused by ______.

In RWD applications with IRS, the inboard and outboard CV joint is a(n)_________ type.

Identify three main components of an FWD half shaft assembly.

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