Housing Attaching Parts Group
Cummins®

The Housing Attaching Parts Group includes a variety of components that are essential to the proper function of a truck's suspension and drivetrain system. The U-bolt is a type of bolt that is shaped like the letter "U" and is used to secure the leaf spring to the axle housing. The leaf spring itself is a long, flat piece of metal that provides support for the vehicle's weight and helps absorb bumps in the road. The shock absorber works in conjunction with the leaf spring to further dampen any shocks or vibrations from rough terrain.

The axle shaft is responsible for transferring power from the engine to the wheels, while the drive shaft transmits torque from the transmission to the rear differential. The carrier bearing, also known as a center bearing, supports and aligns these two shafts where they meet in the middle of their span. Finally, there's also a component called a center support bearing (part number: 3871602), which serves a similar function but is located at one end of an extra-long drive shaft.

All of these parts work together harmoniously to ensure that your truck can handle heavy loads, rough terrain, and all kinds of driving conditions without breaking down or suffering damage.
