Tools Required: Socket set, torque wrench, marker for alignment.
Use a marker to note the alignment of the driveshaft to the differential and transmission.
Remove the bolts securing the U-joint to the driveshaft using the socket set.
Carefully slide the driveshaft out from the U-joint connection.

4. Replace U-joint

Tools Required: U-joint removal tool or hammer and appropriate sockets.
Use the U-joint removal tool to press out the old U-joint from the yoke.
