Fill in the Gaps47.Complete the following statement about crown wheel and pinion diagnosis using the following words.Words: Accelerating, Float, Gear, Noise, Tooth, VehicleCrown wheel and pinion noise originates from poorToothcontact and may be noticed on drive, overdrive orFloat. It can be more pronounced on one of these than on the others.Drive noise is most pronounced whenAccelerating, as the gear teeth are under load. The bearings are alsounder load so that any lack of preload will allow theGearteeth to change their area of contact.Noise on overdrive occurs as theVehicledecelerates from medium speeds, while floatNoiseoccurs underlight cruising conditions.True or False question48.Rough pinion bearings will produce a continuous whine, which will persist when coasting in neutral, right downto low speed.☒Trueor☐False
True or False question49.Faulty rear-axle bearings produce a growling noise, which is hard to distinguish from a differential noise.
