why do you think land Rover used a double cardon joint to begin with? do you think they got some type of 2 for 1 sale and figure what the hell lets try these for a change. I vote you use the defender shaft.

Honestly I don't know why lr used a double cardan. It can be anything...

Maybe it is for comfort rather than reliability? Who knows

IMHO, Too much theories instead of hands-on experience...

Put the single cardan shaft on and go wheeling. Check back periodically with your experiences. Let's put the theories to bed. No data like real world conditions data

Why not just order the three u-joints and centering ball and have your prop shaft rebuilt in Brazil?

You do understand that there is more to a driveshaft than a simple rotating assembly to help propel your truck down the road? Are you familiar with angular velocity? Check it out:

CV (or Constant Velocity) joints are a class of joint which are designed to eliminate the variation in angular velocity that plagues u-joints

The simplest CV joint is simply two u-joints connected end to end, usually the center section is called an H-yoke because of its shape. In this manner, the angular velocity variations of one joint are canceled by the joint on the other end. Since there are two joints on DC the operating angle capacity of the double cardan joint is twice that of a single cardan joint.

Listen, I'm not hear to challenge you. I'm simply trying to help out a fellow enthusiast by passig on knowledge I obtained over my years.

Excellent Read:

Thanks for your explanation coors!

I understand that a dc has twice angle capacity, but that doesn't mean a single joint angle capacity isnt enough for the d2. Is it what you're saying?

You're welcome!

My suggestion.
Give that article a good read. Then make the decision to add the Defender shaft.

Definitely keep us updated. That's really not that extreme of an angle I don't think. Look forward to seeing how it lasts.
