How to Disassemble a Driveline

The driveline is the main component that enables the rear end differential to turn the rear wheels. A driveline connects to the yolk on the back of the transmission. The other end of the driveline connects to the yolk on the rear differential. When the transmission is engaged, the transmission yolk turns the driveline which in turn turns the yolk on the rear differential. The gears inside of the differential then turn the rear axles which then turn both rear wheels. Over time the u-joints inside of the driveline will wear down and need to be replaced.

Instructions

1

Park the vehicle on a level surface and engage the parking brake.

2

Wait about an hour for the driveline to cool down. Slide under the middle side of the vehicle and locate the yolk on the back of the transmission. The front of the driveshaft is attached to the transmission yolk. Loosen and remove the four u-joint strap bolts that connect the driveline to the transmission yolk with a ratchet and a socket. Remove the bolts and the straps and place them in a safe area.

3

Put on the safety glasses to keep any metal shavings out of your eyes. Tap the top center of the driveline yolk with a hand held sledge hammer until the end of the driveline is slid back enough to remove it from the transmission yolk. The driveline is adjustable, It will slide backwards or forwards. Lower the front of the driveline to the surface.

4

Move to where the end of the driveline connects to the yolk on the rear end. Loosen and remove the four u-joint strap bolts with a ratchet and a socket. Remove the bolts and the straps and place them in a safe area. Pull the end of the driveline off of the rear end yolk and lower it to the surface. Push the driveline out from under the vehicle.

5

Place each end of the driveline onto a block of wood. Remove the front u-joint from the drive line by turning the drive line so that one of the u-joint caps is facing upward. Locate a deep-well socket that will fit into the driveline yolk hole and onto the u-joint cap. Tap the deep-well socket with the hand held sledge hammer until the bottom u-joint cap comes off of the u-joint. Pull the bottom cap off of the u-joint.

6

Rotate the driveline 90-degrees so that the u-joint with the missing cap is facing upward. Remove the other c-clip with the c-clip pliers. Tap the bare u-joint with the hammer until the other cap comes out of the bottom of the yolk. Pull the cap off and wiggle the u-joint out of the driveline yolk with your hands. Move to the other end of the driveline and repeat the same process as explained in the steps above to remove the u-joint from the driveline yolk.
