Core Functions and Structure
Driveshaft Body: Constructed from high-strength seamless steel tubing, it transmits power from the forward transmission to the rear.
Hanger Assembly (Center Support Bearing): The driveshaft features a metal hanger (center bearing mount) equipped with a rubber cushion in its midsection. This hanger is bolted directly to a crossmember of the truck's chassis frame.
Primary Function: It suspends and supports the high-speed rotating driveshaft, preventing bending or violent oscillation caused by excessive length; simultaneously, the rubber bushing within the hanger significantly absorbs driveline vibrations and reduces chassis noise.

Common Fault Symptoms
1. Abnormal noise from under the vehicle during start-up or acceleration: Usually caused by the aging, cracking, or breakage of the rubber within the support hanger, leading to violent oscillation and impact of the driveshaft against the hanger.
2. High-frequency vibration or a numbing sensation in the chassis while driving: Often caused by wear, lack of lubrication, or eccentric rotation of the center support bearing (intermediate bearing).
3. Abnormal noise during high-speed driving: Wear of the internal bearing balls.

Precise Mounting Points
1. Front End (Input End): Connects to the output shaft flange of the truck's transmission via a cross-type universal joint flange.
2. Middle Section (Hanger Bearing Mount): The intermediate bearing hanger (center support bearing) is rigidly secured-using two high-strength bolts-directly beneath the vehicle's chassis frame (crossmember).
3. Rear End (Output End): Connects to the next driveshaft section (or directly to the intermediate axle's differential housing) to continue transmitting power toward the rear.
