I'm likely going to need new u-joints. The one's on my truck are very loose and with the new mill going in and harder shifting transmission I'm going to need to replace them.

I noticed that Durlast makes a sealed, maintenance free u-joint. Some things that Durlast makes have actually been decent quality in my book. Other things have been garbage. I was wondering what you all thought about these u-joints.

In addition, how do I measure the size of the u-joint. I measured the cap diameter (1.125) and the cap to cap length (3.626 IIRC) but that doesn't line up with any of the measurement I see here so I'm taking the wrong measurement but don't know what.
