I have a silent lurch/bump in the drive train as I come to a stop and then when I first move out. Shifts are fine, no noise, no clunks. I serviced the tranny, replaced the filter, etc. torqued the valve body bolts. Looking at the slip joint on the front end of the drive shaft, I see a rubber boot with "clamps" on each end of the boot and no grease fitting. So............how do I grease the slip joint? 1999 Ranger 3.0V6, 4X4, automatic. This vehicle only has 91K miles on it, but it is 20 years old, and it has sat a lot in recent years, in a dry climate.

 

You need to slide back the rubber boot and reclamp it when done, read here: https://www.ranger-forums.com/drivet...-sticky-73528/

If u-joints are original then dropping the drive shaft and changing them at the same time you lube slip joint is not a bad idea
