I need to replace my u joints, and am just curious which brand to go with? Greaseable or non-greaseable? Where is the best place to buy? Thanks!

Nongreasable because there not hollow inside. dave

I went with greasable ones, not worried about load as I never get into anything to rough(sad but true)

Most of the techs on here seem to recommend Spicer non greasable.

I'm pretty sure those are what's stock on are trucks
