Ah crap wrong u joint??

I think I have bought the wrong u joint.. what i have is a flaming river 3/4 dd to 3/4 dd. The end of the fr column is 3/4 dd hollow. Does a piece of 3/4 go into it or does a one inch u joint go over it.

What are you using for column?

If there is a hollow DD coming out of it, you need another piece to mate it up. The hollow DD should slip into another large DD hollow that has a rag joint on it. The other end of the rag joint will have a solid DD (3/4) which will slip into your 3/4 DD U joint.

The reason why you can't join the hollow to your U-joint is because the set screw will crush the hollow and you can't put a pin in it because it will rip it out over time. The inner and outer hollow DD's are meant to telescopic in case of an accident and not drive the steering column through your chest.

Contact Flaming River for more info, or go back to the junk yard and study a few more similar columns and you'll see what and how they work.

As mentioned, your DD hollow shaft is meant to have a DD solid shaft that telescopes inside of it. There is no U-joint to hook straight to the DD hollow shaft as it will collapse as has been noted.
