Precision U" joints

[mudjunkie 82]

I've heard a lot of folks say these U"joints are junk but after yesterday I can say that they are not junk. I was hitting it hard in a creek bed that is shale and deep mud. I broke both ears off a 35 spline 4340 stub shaft and one off the inner shaft of my Dana 60 and no damage to the U" joint.........

The D60 shaft joint?

Pics please. A true cromo ear should break even an 806 body.

I hadn't heard that they were junk, and I've been running them on my D44 with 44's with very few problems, usually the axle breaks first. Gonna have to upgrade soon though, I'm about out of stock spares. Of course keep in mind that I sell them where I work ...

These ujoints were all I could get my hands on locally. So I put 2 brand new ones in. I had not had a single issue with breaking the 30 year old stock spicer ones. Just thought that it would be a good idea to get new ones in there.
Day one.

Day two.

So needless to say, they didnt even last a single trip. I replaced the first one with a old unit I had. It held up over the new one. I will never run one of these in my wheeling rig again. The 60 is getting spicers.
