U Joints
Hello, I am fairly new to Excursions and I am planning to replace my U joints as the truck is 12 years old and I want new ones before taking off with my travel trailer this summer. Now, in looking at the Moog website, I see they offer a package deal, but one offering shows three U joints for the rear drive shaft and the other shows two. My Ex has only two, but I would like to know why some have three. As I said, I am new to Ex's. Thanks in advance.

I have the double cardan, and actually had failure. The research I did, trying to figure out what was wrong, led me to this assumption. The double joint is supposed to be stronger, that is where things change. It also has a centering ball and it is all built into the yolk. when the u-joints go the centering gets destroyed. The entire head must be replaced, this is a basic drive shaft rebuild, and then balance. My truck was not drive able, it felt like there were issues with the trans, or transfer case. I found the problem when I pulled the driveshaft to tow the ex home. Since the rebuild, it has been a dream to drive again. It would have been so much easier to have just changed 2 u-joints and then been on my merry way. The pinion angles are also different with the two different drive shafts.

after this winter I will be rebuilding my front shaft too, again 1350x joints and there is a driveline shop locally that stocks that Neapco ball socket, but I don't have the part number handy
edit: Neapco 7-0081NG i'm pretty sure is the ball joint

you can replace just the centering ball. Moog makes a crappy kit and Neapco makes a decent one. i used Spicer 1350x joints but they dont make the ball socket any more.

just look for the biggest, I cheated, my drive line place actually carries them and I got the whole thing for less than what I could find the parts alone for.
