You may have seen the slip yoke lubrication 'how to' nestled in the rear pinion seal replacement 'how to'. https://www.ford-trucks.com/forums/1...l#post10449902.

It's also very well covered here.

My local parts store didn't carry this, but spicer makes a universal one that works fine. Your local driveline shop will likely have it. I paid $15.40.

1. Block all the tires, when you remove the driveshaft, the Ex will want to roll away.

2. Mark your tcase/driveshaft sections with a silver sharpie.

3. Get out your 12mm hex wrench and remove the 4 bolts that hold the front of the driveshaft to the transfer case.

4. It's heavy, so support it. Loosen the smaller end of the boot to remove the front stub-shaft from the longer drive shaft (still attached to the differential) to expose the splines.

5. Remove the old boot completely, attach the new boot to the stub-shaft. If you have the band tightener tool, use it, otherwise use pliers, needle nose or MacGyver zip ties.

6. Re-grease the slip joint. Inspect u-joints as needed. If your rear pinion is leaky, chop, chop, get on it!

7. Re-attach the stub-shaft to the long driveshaft on the truck, not forgetting to put on the smaller diameter steel band first. Make sure your sharpie marks line-up.

8. Re-attach the driveshaft to the Tcase flange using 4 12mm hex bolts. You may need to turn the flange a few degrees to match up the holes. Tighten per specs or 'nice 'n tight'.

9. Un block the vehicle before driving away.

 

its the little things that make the difference

 

Thank you for the write up. It helped, especially the part number for the boot.
