This is the ultimate failure mode for a universal joint – literally breaking, and allowing the drive shaft to drop to the pavement, no longer transferring power.

Why does my transmission jerk when I shift gears?

Transmission fluid that has aged and lost some of its frictional properties can also lead to poor shift quality. When your vehicle’s computer tells the transmission to shift gears, hydraulic pressure (provided by the fluid) squeezes a series of plates together inside a clutch pack…

What causes the U-joint of a drive shaft to squeak?

Since the bearing portion of each universal joint twists a small amount with each rotation of the driveshaft (but always in the same location) the grease can evaporate, or be thrown out of the bearing cup. The bearing becomes dry, metal-to-metal contact is made, and the u-joint bearings will squeak as the drive shaft rotates.
