I'm doing a rebuild of my front CV joint. The vehicle is a 72 K5 blazer and the centering yoke, h-member, weld yoke, and ujoints all say spicer. The ujoints measure out to be 1310s. The CV ujoints do not have grease zerks but the front differential does. So here is my question. What spicer part numbers should I order? I need 3 new ujoints and a new centering yoke (whole assembly with ball, spring, dust shield, & needle bearings). These are the part numbers I found but I don't know if they're right. Ujoint 5-153x (quanity 3) Ball Centering Kit 211355x (quanity 1) The pin diameter of the spicer weld yoke is 0.485. I assume it is OK to put greasable ujoints in the CV unit.
