Drive Axles and Differentials (final)
Both
Tech A says that a gear tooth pattern can identify excessive ring gear runout. Tech B says that gear patterns are not accurate if there is excessive ring gear runout. Who is correct?
Tech B
Tech A says that a hunting gearset is one in which one drive pinion gear tooth contacts only certain ring gear teeth. Tech B says that a partial nonhunting gearset is one in which one pinion tooth contacts only six ring gear teeth. Who is correct?
Both
Tech A says that limited slip differential clutch packs are designed to slip when the vehicle turns a corner. Tech B says that a special additive is place in the hypoid gear lubricant to promote clutch pack slippage on corners. Who is correct?
Both
Tech A says that side-bearing preload limits the amount the differential case is able to move laterally in the axle housing. Tech B says that adjusting backlash sets the depth of the mesh between the ring and pinion gears' teeth. Who is correct?
cross grove
Which type of joint has a flatter design than any other?
Both
While reviewing the procedure for setting backlash: Tech A says that backlash is adjusted along with side-bearing preload by loosening or tightening side=bearing adjusting nuts. Tech B says that normally, to decrease the amount of backlash, a thin shim is installed on one side of the gear and a thick one on the other side. Who is correct?
a leak or noise
how are problems normally first noticed with the differential and drive axles?
inboard and plunging
in front-wheel drivetrains, the CV joint nearer the transaxle is what type?
double-cardan u joint
large cars with long drive shafts often use a double u joint arrangement called a what?
position; function; design
name the 3 ways in which CV joints are classified
higher and greater
the double-offset CV joint is typically used in applications that require __________________ operating angles and __________________ plunge depth
yoke
the drive shaft component that provides a means of connecting two or more shafts together is the what?
cross joint or four-point joint
the single cardan/spicer universal joint is also known as the what?
removable type
what type of axle housing resembles a banjo?
dead axle
what type of axle merely supports the vehicle load and provides a mounting place for the wheels?
three-quarter floating axle shaft
what type of floating axle has one wheel bearing per wheel on the outside of the axle housing?
double cardan universal joint
what type of u joint does these describe? - the speed fluctuations of the two-u-joints cancel each other out - it is classified as a constant velocity u-joint - a centering ball socket is inside the coupling yoke between the two universal joints
semifloating
which type of driving axle supports the weight of the vehicle?
Both
Tech A says that some axle shafts are retained in the housing by a plate and bolts. Tech B says that a C washer clip retains some axle shafts in the housing. Who is correct?
Both
Tech A says that when a car is moving straight ahead, all differential gears rotate as a unit. Tech B says that when a car is turning a corner, the inside differential side gears rotates slowly on the pinion, causing the outside side gear to rotate faster. Who is correct?
ball-type or tripod
specific classification for the design of a CV joint
fixed or plunged
specific classification for the function of a CV joint
inboard or outboard
specific classification for the position of a CV joint
road test
that type of test is the best way to determine which CV joint is faulty?
plunge and inboard
A CV joint that is capable of in-and-out movement is what type?
Tech B
While diagnosing the cause of a clicking noise that is heard only when the car is turning: Tech A says that the most probable cause is a worn wheel bearing. Tech B says that the most probable cause is a worn outboard CV joint. Who is correct?
Both
While discussing different types of ring and pinion gearsets: Tech A says that with a nonhunting gearset, each tooth of the pinion will return to the same tooth space on the ring gear each time the pinion rotates. Tech B says that when a hunting gearset rotates, any pinion gear tooth is likely to contact each and every tooth on the ring gear. Who is correct?
Neither
While discussing the possible causes for a clunking noise during acceleration: Tech A says that an outer CV joint could be the cause. Tech B says that runout in the drive axle may be the cause of the problem. Who is correct?
