Step 8
- Remove the coupler from the upper main pipe.
- Just the upper main pipe assembly, with the upper driveshaft, should remain.
- Your new upper driveshaft should come with a black socket on one end. If this isn’t the case, install a new inner socket and outer socket on the new driveshaft.
- Your new upper driveshaft may not come already installed in the new upper main pipe. If so, apply grease to the outside of the upper driveshaft, then slide it into the upper main pipe, with the black socket facing toward the open end of the upper main pipe.
