I'm going to WNC and in a hurry to replace rear U joints prior to trip.

Looking online is making me batty - are there only two variations of u joints for the rear DS? Or More?

I thought dbl cardan vs one piece was enough info (I have a one piece) but wanted to make sure.

Here's the Dana decal... TIA!

 

Rock auto (for example) - I assume I need to measure the yoke span?

Buying U-joints online (especially ones sold as genuine spicer) is a mixed bag because there are A LOT of counterfeits out there. Pretty much anything on Amazon or eBay has like an 80% chance of being a fake. Venture truck parts (see link above) is good, RockAuto is usually good, but because they often ship to you directly from third parties, some of those third parties will "accidentally" let a counterfeit sneak in sometimes. So I stick with Venture truck parts for anything where I want an actual genuine spicer part (sometimes it doesn't matter , like some of the trail spares I carry in the Jeep are RockAuto "spicer" stuff).
