what occurs in a differential during cornering?
a. the inside axle side gear turns faster than the outer axle side gear
b the case turns at the same speed as the drive shaft
c the crown gear will slow down slightly
d the pinion/spider gears rotate on the pinion shaft

Tech B says that if the bearings on the input shaft, countershaft, or main shaft are worn, either front or rear, a growling noise will result when stopped in gear. Who is correct?arrow_forward

It can be more pronounced on one of these than on the others.Drive noise is most pronounced when ________________, as the gear teeth are under load. The bearings are also under loadso that any lack of preload will allow the ________________ teeth to change their area of contact.Noise on overdrive occurs as the ________________ decelerates from medium speeds, while float ________________occurs under light cruising conditions.arrow_forwardA clicking noise during transrnission/transaxle operation may be an indication of ________. a. worn mainshaft (input shaft) bearings b. faulty synchronizer operation c. failed oil seals d. worn, broken, or chipped gear teetharrow_forward
