I have a '87 4.0 auto 2wd. It hasn't really been out of town for several months, and on the last road trip, aside from the cruise, it was fine.
It now has a vibration above 60mph.
Naturally, I checked the u-joints.... they were fine, however the slip yolk moved a lot. Also, when I wiggled it there was a slight metallic clunk from the driveshaft.
then I noticed this....
( I noticed this after loosening the bolts :yes: )
While I did paint across the yolks, I did not put the arrow there.
It kind of looks like the driveshaft is maybe starting to separate, to me.
Has anyone had or noticed anything like this?
At first I was thinking just a new slip yolk, but now .... :dunno:
