Any thoughts on which manufacturer makes the best U joints? Not lookin to slam anyone or get into a chevy/Ford argument, just needing to replace mine soon and lookin' for ideas. 
Thanks!

Thanks!
Well, in my experience with my 2nd gen truck, I would have to say whatever came on it. At 216K, I have yet to replace a U-joint anywhere on the truck.

cold forged spicers, non greaseable. hands down the strongest, longest lasting. Triple seals to boot.
And those would be non-greasable spicer's?
