I have always replaced my worn U-joints with Toyota OEM U-joints
they have the grease zerk right on them
better than just the cheap replacment ones avaiable from Autozone
I wish some of the HD U-joint manufacturers made them for us
Tom Woods Drivelines makes a new u joint for our trucks. It is offset 10 degrees to allow a greater droop without binding the u-joint. Price at time of publication was about $60 and they are said to be much stronger than stock.
