Oh brother.... This makes me appreciate the earlier Gen III trucks even more.
Makes me want to run out and buy a 1999 Dakota now. If I ever get a Gen III
its going to be a 99 or older - I don't like what they did to the thing in 2000
and up (mechanically).
I don't know what you would call that joint. I can't quite figure out how it
works - just from those pictures. It must have some kind of tripod-socket -
like a front drive axle. But I've never seen anything like that on a front
shaft. Reall weird. Yet another product of the Daimler Legacy (spits).
