Hi, i am trying to replace the old original u joints, but i wanted to ask if greasable , or non greasable is better, or does it make any difference in at all, just wanted to ask if you prefer one over the other,,,thanks,,,,

 

Greaseable tend to last longer..... provided you remember to grease them.

 

The argument is that non greasable is stronger because they don't have the grease channel in them. Witch is true but as long as you aren't drag racing, extreme off roading or heavy trailer pulling you should be fine with greasables. And all ways buy Spicers!

 

...and you have the special narrow fitting to get in and grease them.
