Final answer:
Drive axles come in two housing types: rigid axle housing, which connects wheel hubs directly and is durable for heavy-duty use, and independent suspension housing, which allows independent wheel movement for smoother rides and better handling.
Step-by-step explanation:
The two housing types used for drive axles are rigid axle housing and independent suspension housing. A rigid axle housing, often encountered in trucks and traditional SUVs, joins the wheel hubs directly, making them move in unison.
This type of axle is known for its durability and strength, which is vital for vehicles that carry heavy loads or traverse rugged terrain. However, it can result in a rougher ride because the movement of one wheel directly affects the other.
On the other hand, independent suspension housing allows each wheel to move independently of the other. This results in improved handling and a smoother ride, especially over uneven surfaces because the movement of one wheel does not cause movement in the opposite wheel.
This type of housing is commonly found in modern passenger cars and is preferred for providing a more comfortable driving experience.
