The correct answer is that the weakness of a front-engine rear-wheel drive car is that the differential is far from the engine, requiring a propeller shaft to connect them. This means that there is an additional component that can potentially fail or require maintenance, and it also adds weight and complexity to the drivetrain system.

A dial test indicator is used to measure the runout or eccentricity of a differential. It is a precision instrument that has a dial face with a needle that moves as the differential rotates. The needle indicates any deviation from the true center, allowing for accurate measurement of runout. Vernier calipers and micrometers are commonly used for measuring dimensions, while a fuller gauge is used for measuring the depth of holes. Therefore, the most appropriate instrument for measuring runout in this context is a dial test indicator.

The final gear and differential gear function to reduce the number of rotations from the transmission in order to increase torque.

The differential case is the component that functions as the support for the ring gear. It holds the ring gear in place and allows it to rotate smoothly. The drive pinion shaft is responsible for transmitting power from the engine to the differential. The side gear is connected to the axle shafts and allows for power distribution to the wheels. The wheel is the component that makes contact with the road surface and allows the vehicle to move.

The correct answer is 90 degrees because a Front Engine Rear Drive system means that the engine is located in the front of the vehicle and the power is transmitted to the rear wheels. This configuration allows for better weight distribution and traction, especially during acceleration. When the vehicle changes direction, the front wheels will turn while the rear wheels maintain their position. Therefore, the angle of change in the direction of motion will be 90 degrees.

When removing the ring gear and differential case, it is important to mark the bearing cap to prevent it from being mixed up or swapped with another one. This is crucial because each bearing cap is specifically designed and fitted for a particular position in the differential case. Swapping or mixing them up could lead to improper installation and potential damage to the differential system. Therefore, marking the bearing cap helps ensure that it is reinstalled in its original position during reassembly.

The correct answer is Type Helical gear. Helical gears are commonly used in vehicles with front-wheel drive. They have angled teeth that gradually engage, resulting in smoother and quieter operation compared to other gear types. The helical gear design also allows for a higher load-carrying capacity, making it suitable for the final drive unit in front-wheel drive vehicles.

The correct answer is "Mesin Belakang Penggerak Depan (Mid Ship Engine Front Drive)". This option states that the engine is located at the rear of the vehicle and drives the front wheels. However, this configuration is not commonly used in vehicles. Most vehicles either have a front engine rear-wheel drive, front engine front-wheel drive, or four-wheel drive.

The given correct answer suggests that the first step in dismantling the differential case is to remove the straight pin (batang pin). This implies that the straight pin is holding some components together and needs to be removed before further disassembly can take place.

Backlash refers to the excessive clearance or play between two mating components, in this case, the ring gear and drive pinion in a differential. This abnormal friction can lead to wear and tear, causing an increase in the distance between the ring gear and drive pinion. Therefore, the correct term for this phenomenon is "backlash."
