How to Replace a Drive Shaft Bearing

Materials Required:

New drive shaft bearing

Socket wrench set

Torque wrench

Safety glasses

Gloves

Steps:

Safety First: Park the vehicle on a level surface, engage the parking brake, and wear safety glasses and gloves.

Locate the Drive Shaft: Identify the drive shaft and locate the worn or damaged bearing.

Remove the Drive Shaft: Use a socket wrench to remove the bolts securing the drive shaft to the transmission and differential.
